How to make Commands with Switches in CMD - windows

Okay so basically I have created a suite of tools to use with the command line (cmd), and I want to add switches to them the same way you would for a command like ipconfig. You have IpConfig and IpConfig /all. My command will be called nettools. Currently it is a batch file inside of the C:\windows\system32 folder that uses the type command to display a text files contents. In this file are the names of the tools and their descriptions. This command does not pause or ask for user input it only displays the info inside of the txt file. How can I add switches such as nettools /? or nettools /snif....
Please watch the following video as the answers provided have also failed to work.

#echo off
SET "parameter=%~1"
if /i "%parameter%" equ "" goto :help
for %%p in (putty tcpview fiddler ) do (
if /i "%parameter:~1%" equ "%%~p" goto :%%~p
rem if /i "%parameter%" equ "%%~p" goto :%%~p
)
goto :wrong_parameter
:putty
start putty (or call putty.bat)
goto :eof
:tcpview
start wget (or call the bat)
goto :eof
and so on. (will not work with "?wget" ) you can use directly START to call the tools if they are in the %PATH% or in the same directory.

Get the last name of a directory path in batch

I've been tasked with writing installation scripts for my company that will be able to install printer drivers on a users computer.
What I have done so far is I've made the script accept a parameter (the printer type brother, xerox, etc..) from there it will gather the relative path to the drivers, and run a forfiles command on the path outputting all the drivers, after that it will ask the user for the correct driver copy it from the network drive to the users desktop, and run it.
What I need to do is the running part, I need to copy the driver to the desktop and somehow get the last directory part (example: user\desktop\test.exe I need to gather the last part test.exe) how can I go about doing this in a functional way?
Basically I would need to split the path by \ and grab the last entry of that list, is this possible in batch?
#echo off
type banner.txt
if [%1]==[] goto usage
:verify_argv
IF '%1'=='canon' GOTO get_canon_path
IF '%1'=='xerox' GOTO get_xerox_path
IF '%1'=='hp' GOTO get_hp_path
IF '%1'=='dell' GOTO get_dell_path
IF '%1'=='brother' GOTO get_brother_path
goto :eof
:get_canon_path
set dir_path=\\mgtutils01\windows7apps\PRINTERS\Canon
goto :install_drivers
:get_xerox_path
set dir_path=\\mgtutils01\windows7apps\PRINTERS\Xerox
goto :install_drivers
:get_hp_path
set dir_path=\\mgtutils01\windows7apps\PRINTERS\HP
goto :install_drivers
:get_dell_path
set dir_path=\\mgtutils01\windows7apps\PRINTERS\Dell
goto :install_drivers
:get_brother_path
set dir_path=\\mgtutils01\windows7apps\Brother\Drivers
goto :install_drivers
:usage
#echo Usage: .\driver [PRINTER_TYPE]
exit /B 1
:install_drivers
#echo Finding drivers...
pushd "%dir_path%"
forfiles /s /m *.exe /c "cmd /c echo #relpath"
set /p to_install="Copy the path of the correct driver and paste here: "
#echo Copying file to %USERPROFILE%, please wait..
xcopy %to_install% "%USERPROFILE%\Desktop"
#echo Installing driver..
pushd "%USERPROFILE%\Desktop"
To get the last element of a file or directory path, you can:
either use a for loop and its ~ modifiers:
set "ITEM=user\desktop\test.exe"
for %%I in ("%ITEM%") do set "NAME=%%~nxI"
echo %NAME%
or call a sub-routine by the call command, pass the path as an argument and again use ~ modifiers:
set "ITEM=user\desktop\test.exe"
call :SUB "%ITEM%"
goto :EOF
:SUB
set "NAME=%~nx1"
goto :EOF
For both variants, the ~nx part extracts the base name (n) and the extension (x) from the last element of the path stored in the reference (%%I or %1). Type for /? and call /? into a command prompt window and read the help texts; you will find all the possible ~ modifiers of for variable references and argument references, respectively.

%errorlevel% returning 0 in loop command

Ok, I've installed Dropbox but it didn't corresponded to what I was looking for so I uninstalled it with Revo Pro.
But, when i open the taskmanager there are still processes related to it running in my computer so I decided to make a batch to look out and delete all files that are related to it.
#echo off
cd c:\
:a
set /p a=Phrase that might be realted to it
for /r %%d IN (*.*) DO (
(
findstr /i /m /c:%a% "%%d"
if "%errorlevel%"=="0" del "%%d"
echo %errorlevel%
)
)
pause
The problem is: when I run findstr using loop even when there is no match for my variable "%a%" in an analized file %errorlevel% returns as 0. But when I use findstr alone and there isn't a match %ERRORLEVEL% returns as 1 and 0 for a match.
If I use it, I'll delete all my PC files haha. What's wrong with the code?
Within a parenthesised series of statements, any %var% is replaced by the value of that variable at the time the verb controlling that statement-sequence (or block) is encountered.
Here, the block is the entire sequence of statements controlled by the for. %errorlevel% is replaced by the status of errorlevel at the time the for is encountered, so probably 0.
If you use
findstr /i /m /c:%a% "%%d"
if not errorlevel 1 del "%%d"
echo %errorlevel%
then the run-time value of errorlevel is used (ie. as it changes through the operation of the loop) and the command means "if errorlevel is not (1 or greater than 1) do this..."
The findstr will set errorlevel to 0 on found, 1 on not found and 2 for file not found(IIRC) so NOT (1 or greater than 1) selects 0 only. Note that in certain esoteric circumstances, errorlevel may become negative, but after a findstr I believe 0..2 is the allowed range.
Not sure what's wrong with the code, but you can probably skip it using the && operand.
findstr /i /m /c:%a% "%%d" && del "%%d" echo %errorlevel%
Thanks to Stephan for correcting the example.
Whenever Windows command interpreter encounters ( being interpreted as begin of a command block, it parses the entire command block up to matching ) marking end of the command block and replaces all %variable% by current value of the variable.
This means in this case that before command FOR is the first time executed, everything from ( after DO up to last ) is processed already with replacing all %variable% references by current value of the appropriate variable. Then the already preprocessed block is executed one (on command IF) or more times (on command FOR).
This behavior can be seen by debugging the batch file. For debugging a batch file first #echo off must be removed or commented out with command REM or changed to #echo on. Then a command prompt window must be opened and the batch file is executed from within this command prompt window by typing its name with full path enclosed in double quotes if path or name contains a space character. The Windows command interpreter shows now all command lines and command blocks after preprocessing before executing and of course the standard messages and the error messages output by the commands or by Windows command interpreter itself in case of a syntax error in batch file.
Opening a command prompt window means running cmd.exe with option /K to Keep window open after execution of a command or a batch script. Double clicking on a batch file starts also cmd.exe for processing the batch file, but with parameter /C to Close the window automatically after batch processing terminated independent on cause - successful finished or an error occurred.
The command prompt window opened before running the batch file remains open after batch processing finished successfully or with an error except the batch file contains command EXIT without parameter /B. So experts in batch code writing test batch files always by running them from within a command prompt window instead of double clicking on them.
Delayed variable expansion is needed for variables set or modified and referenced within same command block as explained by help of command SET output on running in a command prompt window set /?.
#echo off
setlocal EnableDelayedExpansion
cd /D C:\
:a
set /P "a=Phrase that might be realted to it: "
for /r %%d in (*) do (
%SystemRoot%\System32\findstr.exe /i /m /c:"%a%" "%%d"
if "!errorlevel!" == "0" del "%%d" >nul
)
endlocal
But for checking the exit code of a previous command there is also if errorlevel syntax as explained by Microsoft in support article Testing for a Specific Error Level in Batch Files.
#echo off
setlocal EnableDelayedExpansion
cd /D C:\
:a
set /P "a=Phrase that might be realted to it: "
for /r %%d in (*) do (
%SystemRoot%\System32\findstr.exe /i /m /c:"%a%" "%%d" >nul
if not errorlevel 1 del "%%d" >nul
)
endlocal
if errorlevel X tests if exit code of previous command or application when it modifies the errorlevel variable at all is greater or equal X. By using if not errorlevel X the check is if last exit code is lower than X which is here a test if exit code is 0.
For understanding the used commands and how they work, open a command prompt window, execute there the following commands, and read entirely all help pages displayed for each command very carefully.

Windows: start a file using a (non-default) shell verb like "edit" from .bat or command-line

How can I start a file with an associated non-default command (shell verb) like "edit", "print", ... from command-line or from a .bat script by using standard Windows means.
(Those extra actions which you get offered on top upon right-click on a file in the Windows Explorer.)
Thus getting the effect of
python -c "import os;os.startfile('somepic.png', 'edit')"
(ShellExecuteEx), but without using extra tools like python, powershell, or so.
The START command does not seem to offer that.
As learned from the comments and after further searching: there seems to be no direct command for that task in standard Windows indeed.
However using a VBScript snippet should be highly compatible and have lowest system requirements. (Works on all machines here directly - from XP - unlike JScript)
VBScript has been installed by default in every desktop release of
Microsoft Windows since Windows 98;1 in Windows Server since Windows
NT 4.0 Option Pack;[2] and optionally with Windows CE (depending on
the device it is installed on).
Example script shellexec.vbs :
' shellexec.vbs : starts a file using a (non-default) shell verb like "EDIT"
' Usage: shellexec.vbs FILE VERB
' Example: shellexec.vbs demo.png EDIT
fn = WScript.Arguments(0)
cmd = WScript.Arguments(1)
Wscript.Echo "ShellExecute """ + cmd + """ on " + fn
CreateObject("shell.application").ShellExecute fn, "", "", cmd, 1
Use from command-line or batch-file:
shellexec.vbs demo.png EDIT
or:
cscript.exe //Nologo shellexec.vbs demo.png EDIT
An example to show how to do it with an one-liner:
mshta vbscript:Execute("CreateObject(""shell.application"").ShellExecute""%SystemDrive%\autoexec.bat"","""","""",""edit"",1:close")
It will open the dummy autoexec.bat file with the application defined to edit .bat files (by default, Notepad).
It is possible to do with batch code what is done by command START for default action of opening a file with associated application.
In the commented batch code below the shell verb must be specified in third line being assigned to environment variable ActionCommand.
The name of the file to edit, printto, ... must be specified as first parameter of the batch file.

Batch file without error dialog

I need to create a batch file that run this command
start chrome
The problem is that I'm not sure that on the machine there is Google Chrome installed. I can't rely on the registry because I will not have admin permissions.
If I run this command on a machine where Chrome is not installed I get this error dialog
(you see "chromex". I used this name to simulate the absence of the software).
Is there a way to avoid to show this dialog?
Next code snippet could help:
#ECHO OFF >NUL
SETLOCAL enableextensions
SET "_chromePath="
If DEFINED programfiles(x86) (
For /F "tokens=*" %%G in (
'where /R "%programfiles(x86)%" chrome.exe 2^>NUL'
) do SET "_chromePath=%%G"
)
If NOT DEFINED _chromePath (
For /F "tokens=*" %%G in (
'where /R "%programfiles%" chrome.exe 2^>NUL'
) do SET "_chromePath=%%G"
)
If DEFINED _chromePath (
echo start "" "%_chromePath%"
) else (
echo chrome.exe not found
)
Note start "" "%_chromePath%" is echoed merely for debugging purposes only.
Resources (required reading):
An A-Z Index of the Windows CMD command line
Windows CMD Shell Command Line Syntax
#echo off
echo Enter 1 to start up Chrome
set /p input=Type here:
if %input%==1 goto chrome
:chrome
echo Starting chrome...
start chrome.exe
pause
The dialog comes from using Start. Execute files directly to see the command prompt's equivlent.
'cat.exe' is not recognized as an internal or external command,
operable program or batch file.
Normally one would open the web site and windows will use the user's choice of browser.
Start "" www.microsoft.com
start "" "c:\windows\help\mmc\htm\mmc_1.htm"
I can't rely on the registry because I will not have admin permissions.
You have read access to most of the registry as a user and you can override most settings and file associations on a per user basis.

How can I make an "are you sure" prompt in a Windows batch file?

I have a batch file that automates copying a bunch of files from one place to the other and back for me. Only thing is as much as it helps me I keep accidentally selecting that command off my command buffer and mass overwriting uncommitted changes.
What code would I need for my .bat file to make it output "Are you sure?", and make me type Y before it ran the rest of the file?
If anything other than Y is typed, it should exit execution on that line.
When I call exit, it closes cmd.exe which is not what I want.
You want something like:
#echo off
setlocal
:PROMPT
SET /P AREYOUSURE=Are you sure (Y/[N])?
IF /I "%AREYOUSURE%" NEQ "Y" GOTO END
echo ... rest of file ...
:END
endlocal
try the CHOICE command, e.g.
CHOICE /C YNC /M "Press Y for Yes, N for No or C for Cancel."
There are two commands available for user prompts on Windows command line:
set with option /P available on all Windows NT versions with enabled command extensions and
choice.exe available by default on Windows Vista and later Windows versions for PC users and on Windows Server 2003 and later server versions of Windows.
set is an internal command of Windows command processor cmd.exe. The option /P to prompt a user for a string is available only with enabled command extensions which are enabled by default as otherwise nearly no batch file would work anymore nowadays.
choice.exe is a separate console application (external command) located in %SystemRoot%\System32. File choice.exe of Windows Server 2003 can be copied into directory %SystemRoot%\System32 on a Windows XP machine for usage on Windows XP like many other commands not available by default on Windows XP, but available by default on Windows Server 2003.
It is best practice to favor usage of CHOICE over usage of SET /P because of the following reasons:
CHOICE accepts only keys (respectively characters read from STDIN) specified after option /C (and Ctrl+C and Ctrl+Break) and outputs an error beep if the user presses a wrong key.
CHOICE does not require pressing any other key than one of the acceptable ones. CHOICE exits immediately once an acceptable key is pressed while SET /P requires that the user finishes input with RETURN or ENTER.
It is possible with CHOICE to define a default option and a timeout to automatically continue with default option after some seconds without waiting for the user.
The output is better on answering the prompt automatically from another batch file which calls the batch file with the prompt using something like echo Y | call PromptExample.bat on using CHOICE.
The evaluation of the user's choice is much easier with CHOICE because of CHOICE exits with a value according to pressed key (character) which is assigned to ERRORLEVEL which can be easily evaluated next.
The environment variable used on SET /P is not defined if the user hits just key RETURN or ENTER and it was not defined before prompting the user. The used environment variable on SET /P command line keeps its current value if defined before and user presses just RETURN or ENTER.
The user has the freedom to enter anything on being prompted with SET /P including a string which results later in an exit of batch file execution by cmd because of a syntax error, or in execution of commands not included at all in the batch file on not good coded batch file. It needs some efforts to get SET /P secure against by mistake or intentionally wrong user input.
Here is a prompt example using preferred CHOICE and alternatively SET /P on choice.exe not available on used computer running Windows.
#echo off
setlocal EnableExtensions DisableDelayedExpansion
echo This is an example for prompting a user.
echo/
if exist "%SystemRoot%\System32\choice.exe" goto UseChoice
setlocal EnableExtensions EnableDelayedExpansion
:UseSetPrompt
set "UserChoice="
set /P "UserChoice=Are you sure [Y/N]? "
set "UserChoice=!UserChoice: =!"
if /I "!UserChoice!" == "N" endlocal & goto :EOF
if /I not "!UserChoice!" == "Y" goto UseSetPrompt
endlocal
goto Continue
:UseChoice
%SystemRoot%\System32\choice.exe /C YN /N /M "Are you sure [Y/N]?"
if not errorlevel 1 goto UseChoice
if errorlevel 2 goto :EOF
:Continue
echo So you are sure. Okay, let's go ...
rem More commands can be added here.
endlocal
Note: This batch file uses command extensions which are not available on Windows 95/98/ME using command.com instead of cmd.exe as command interpreter.
The command line set "UserChoice=!UserChoice: =!" is added to make it possible to call this batch file with echo Y | call PromptExample.bat on Windows NT4/2000/XP and do not require the usage of echo Y| call PromptExample.bat. It deletes all spaces from string read from STDIN before running the two string comparisons.
echo Y | call PromptExample.bat results in YSPACE getting assigned to environment variable UserChoice. That would result on processing the prompt twice because of "Y " is neither case-insensitive equal "N" nor "Y" without deleting first all spaces. So UserChoice with YSPACE as value would result in running the prompt a second time with option N as defined as default in the batch file on second prompt execution which next results in an unexpected exit of batch file processing. Yes, secure usage of SET /P is really tricky, isn't it?
choice.exe exits with 0 in case of the user presses Ctrl+C or Ctrl+Break and answers next the question output by cmd.exe to terminate the batch job with N for NO. For that reason the condition if not errorlevel 1 goto UserChoice is added to prompt the user once again for a definite answer on the prompt by batch file code with Y or N. Thanks to dialer for the information about this possible special use case.
The first line below the batch label :UseSetPrompt could be written also as:
set "UserChoice=N"
In this case the user choice input is predefined with N which means the user can hit just RETURN or ENTER (or Ctrl+C or Ctrl+Break and next N) to use the default choice.
The prompt text is output by command SET as written in the batch file. So the prompt text should end usually with a space character. The command CHOICE removes from prompt text all trailing normal spaces and horizontal tabs and then adds itself a space to the prompt text. Therefore the prompt text of command CHOICE can be written without or with a space at end. That does not make a difference on displayed prompt text on execution.
The order of user prompt evaluation could be also changed completely as suggested by dialer.
#echo off
setlocal EnableExtensions DisableDelayedExpansion
echo This is an example for prompting a user.
echo/
if exist "%SystemRoot%\System32\choice.exe" goto UseChoice
setlocal EnableExtensions EnableDelayedExpansion
:UseSetPrompt
set "UserChoice="
set /P "UserChoice=Are you sure [Y/N]? "
set "UserChoice=!UserChoice: =!"
if /I not "!UserChoice!" == "Y" endlocal & goto :EOF
endlocal
goto Continue
:UseChoice
%SystemRoot%\System32\choice.exe /C YN /N /M "Are you sure [Y/N]?"
if not errorlevel 2 if errorlevel 1 goto Continue
goto :EOF
:Continue
echo So you are sure. Okay, let's go ...
endlocal
This code results in continuation of batch file processing below the batch label :Continue if the user pressed definitely key Y. In all other cases the code for N is executed resulting in an exit of batch file processing with this code independent on user pressed really that key, or entered something different intentionally or by mistake, or pressed Ctrl+C or Ctrl+Break and decided next on prompt output by cmd not terminating the batch job.
For even more details on usage of SET /P and CHOICE for prompting user for a choice from a list of options see answer on How to stop Windows command interpreter from quitting batch file execution on an incorrect user input?
Some more hints:
IF compares the two strings left and right of the comparison operator with including the double quotes. So case-insensitive compared is not the value of UserChoice with N and Y, but the value of UserChoice surrounded by " with "N" and "Y".
The IF comparison operators EQU and NEQ are designed primary for comparing two integers in range -2147483648 to 2147483647 and not for comparing two strings. EQU and NEQ work also for string comparisons, but result on comparing strings in double quotes after a useless attempt to convert left string to an integer. EQU and NEQ can be used only with enabled command extensions. The comparison operators for string comparisons are == and not ... == which work even with disabled command extensions as even command.com of MS-DOS and Windows 95/98/ME supported them. For more details on IF comparison operators see Symbol equivalent to NEQ, LSS, GTR, etc. in Windows batch files.
The command goto :EOF requires enabled command extensions to really exit batch file processing. For more details see Where does GOTO :EOF return to?

Here's my go-to method for a yes/no answer.
It's case-insensitive also.
This just checks for the errors given by the input and sets the choice variable to whatever you require so it can be used below in the code.
#echo off
choice /M "[Opt 1] Do you want to continue [Yes/No]"
if errorlevel 255 (
echo Error
) else if errorlevel 2 (
set "YourChoice=will not"
) else if errorlevel 1 (
set "YourChoice=will"
) else if errorlevel 0 (
goto :EOF
)
echo %YourChoice%
pause
You can also use 'Choice' command
#echo off
echo Sure?
CHOICE /C YN
IF %ERRORLEVEL% EQU 1 goto CONTINUE
IF %ERRORLEVEL% EQU 2 goto END

If you want to the batch program to exit back to the prompt and not close the prompt (A.K.A cmd.exe) you can use "exit /b".
This may help.
set /p _sure="Are you sure?"
::The underscore is used to ensure that "sure" is not an enviroment
::varible
if /I NOT "_sure"=="y" (
::the /I makes it so you can
exit /b
) else (
::Any other modifications...
)
Or if you don't want to use as many lines...
Set /p _sure="Are you sure?"
if /I NOT "_sure"=="y" exit /b
::Any other modifications and commands.
Hope this helps...

for /f "tokens=* delims=" %%# in ('yesnopopup.bat') do (
set "result=%%#"
)
if /i result==no (
echo user rejected the script
exit /b 1
)
echo continue
rem --- other commands --
the user will see the following and depending on the choice the script will continue:
with absolutely the same script you can use also iexpYNbutton.bat which will produce similar popup.
With buttons.bat you can try the following script:
#echo off
for /f "tokens=* delims=" %%# in ('buttons.bat "Yep!" "Nope!" ') do (
set "result=%%#"
)
if /i result==2 (
echo user rejected the script
exit /b 1
)
echo continue
rem --- other commands --
and the user will see:
I would do it in the following way to make sure the testing and variables are correct during looping etc..
:: rem at the top of the script
setlocal enabledelayedexpansion
:: choice example
CHOICE /C YNC /M "Continue? Press Y for Yes, N for No or C for Cancel."
If /I "[!errorlevel!]" NEQ "[1]" ( GOTO START_OVER )
There are so many answers, but none of them seems to be simple and straight forward. This is the code I am using:
choice /M "Do you want to continue?"
if %errorlevel% EQU 1 (
... run your code lines here
)
First, open the terminal.
Then, type
cd ~
touch .sure
chmod 700 .sure
Next, open .sure and paste this inside.
#!/bin/bash --init-file
PS1='> '
alias y='
$1
exit
'
alias n='Taskkill /IM %Terminal% /f'
echo ''
echo 'Are you sure? Answer y or n.'
echo ''
After that, close the file.
~/.sure ; ENTER COMMAND HERE
This will give you a prompt of are you sure before continuing the command.
Open terminal. Type the following
echo>sure.sh
chmod 700 sure.sh
Paste this inside sure.sh
#!\bin\bash
echo -n 'Are you sure? [Y/n] '
read yn
if [ "$yn" = "n" ]; then
exit 1
fi
exit 0
Close sure.sh and type this in terminal.
alias sure='~/sure&&'
Now, if you type sure before typing the command it will give you an are you sure prompt before continuing the command.
Hope this is helpful!
