Running a friend's batch file with this line
for /F "tokens=1 delims=ΒΆ" %%i in ('which synplify_pro.exe') do set synplify_path=%%~dpi
the var synplify_path is getting set with c:\cygdrive pre-pended.
I just want the windows part.
Is there a way to prevent the pre-pend or get back just the windows part?
Well, you could simply remove that part from the result.
If it is always there after the loop, you could simply cut it off like this:
SET synplify_path=%synplify_path:~11%
where 11 is the length of the string c:\cygdrive. If there's a \ just after the offending string and it needs to be dropped too, make it 12.
Alternatively you could do like this:
SET synplify_path=%synplify_path:c:\cygdrive=%
This will replace all the entries of c:\cygdrive in %synplify_path% with an empty string, i.e. it will simply remove that substring. This method may be better in case there's a chance that c:\cygdrive could be absent from the result for some reason: the method will leave the string unchanged if the string doesn't contain c:\cygdrive.
I'm not sure if you shouldn't actually try to resolve the issue with the command that doesn't like c:\cygdrive in the path, though...

I have a variable from a text file.
set /p namz=<"playersname.txt"
Right now if I echoed this, it would echo the entire contents of the file.
The Contents of playersname.txt include the following,
theplayernameis:Player One
I need a code that I can use in .bat to help me to extract everything after the ":" from the .txt file while ignoring everything else before it, "Player One" then it needs to store it in another variable which I can call upon anytime I want it.
I've been racking my brain on this, trying to come up with a solution, been forum hopping for a long time, haven't quite found what I needed yet. Please help..
You have a single-line textfile, you need the second token after a delimiter that might be : or /:
for /f "tokens=2 delims=:/" %%a in (playersname.txt) do set namz=%%a
add every possible delimter to delims=
SOLVED!
Update: It figures moments after posting for help which is something I never do I'd figure it out...I tend to over think things, and that was the case here, it was just so simple! >.<
Solution:
(This worked under Windows 7 Ultimate 64 Bit)
Set var=
Set var=SomeText %var1% %var2% %var3%
Echo %var% > output.txt
See an explanation in my answer below.
I've been searching and trying several posts here similar to my question for hours with no success. I'm not new to Programming in BATCH but I have memory problems and thus can't always remember things. It also doesn't help that I program in other languages on other platforms which usually means I'm trying to use *nix shell commands in my Windows Batch scripts >.<
I've gotten quite close with some examples but nothing that works as needed.
Ideally, I'd like this work to work on Windows 7, 8, 8.1, Vista and 10 as that is the intended target.
This is what I need to accomplish:
The user will answer a series of questions, each question is stored into a .txt file (or variable if you prefer. I just used text files because of a past project where I ran into issues with variables that couldn't be solved and text files worked). The lines in each text file will need to be output into a single text file, on a single line which will then be read back in as a variable and run. Again, you could just use and combine the variables in your example if that's easier for you or both of us ;P
This is a snippet example of how I was doing it
SET file1=
SET /P file1=file1:%=%
ECHO %file1% > file1.txt
Then
copy /b file1.txt + file2.txt + file3.txt + file4.txt output.txt
Here is how I'd like the result to look
toolkit /S "C:\ToolKit Bravo\Data\etc" "D:\ToolKit Bravo\Data\Ops"
The "" quotation marks are necessary. The output MUST be EXACTLY as shown above for the example I've given. The "/S" & paths are variable NOT fixed!
Here is the best I've been able to come up with using variables..
"toolkit /S "C:\ToolKit Bravo\Data\etc" "D:\ToolKit Bravo\Data\Ops""
Update 2 - An explanation as requested:
The paths in the above example directly above this are not fixed! This was an Example Only. "toolkit" is fixed, this doesn't change. "/S" is an option selected by the user to pass on to the "toolkit". Both the source and destination paths are again input by the user in "quotation" marks. They're not fixed paths.
As you can see the result is surrounded by quotations which is NOT acceptable. And Please remember, I NEED the quotations around the paths in the end result, so removing them all is NOT an option!
Any help is greatly appreciated! Thank you for your time.
Just take all of the characters between the quotes.
SET X="toolkit /S "C:\ToolKit Bravo\Data\etc" "D:\ToolKit Bravo\Data\Ops""
ECHO %X%
SET Y=%x:~1,-1%
ECHO %Y%
Solution:
This solved my problem under Windows 7 Ultimate 64 Bit
Set var=
Set var=SomeText %var1% %var2% %var3%
Echo %var% > textfile.txt
Using the SET command I first made sure the variable or var for short was empty. Using this command:
Set var=
I then proceeded to create my variable using all of the other variables I had created and wanted to combine using this line of code:
Set var=SomeText %var1% %var2% %var3%
Note that I have preceded the variables with "SomeText". This is where I'll place the name of the .exe I'm passing the arguments to, but it can be anything you want included. I also need spaces between each variable so I've left spaces between them in the example code. If you don't want the spaces simply remove them, and you'll have 1234, instead of 1 2 3 4.
Finally I send the combined variable out to a .txt file.
Echo %var% > textfile.txt
However, you could also simply call the new variable now like this:
%var%
The thing is that I want to do this JUST by using Windows bash utils (so it can be easily used without other applications like Cygwin/grep on other workstations).
Also this command will be in a larger script that uses the extracted string as a part of a filename.
ex: this is the line in the searched file
" <DataVersion>A0C2</DataVersion>"
A0C2 is the string that I need but it can have a different value like X1Z4 but is always 4 alfanumeric characters long.
<DataVersion> and </DataVersion> are always present.
Also the line may occur more than once but I only need the first to be considered.
I found out in the mean time the answer to my own question.
set ROW=
set VERSION=
for /f %%i in ( 'findstr "<DataVersion>" file.txt' ) do #set ROW=%%i
set VERSION=%ROW:~x,y%
where:
x is the number of characters you want to skip in ROW and
y is the number of characters you want to save in VERSION
so in case
findstr "<DataVersion>" file.txt
returns and sets ROW to this value:
<DataVersion>AX23</DataVersion>
then:
set VERSION=%ROW:~14,4%
will set VERSION to AX23
I have the following command in a windows batch script
echo =%%k-16,INDIRECT.EXT^("'C:\Users\...\Analysis\[ObsStreamflow.xlsx]Sheet1'^!A%%k"^),INDIRECT.EXT^("'C:\Users\...\Analysis\[sim%%j.xlsx]Sheet1'^!B!val!"^),^=C%%k/1000,^=D%%k-B%%k,^=ABS^(E%%k^),^=(E%%k^)^^2,=^(B%%k-B10^),=Sqrt^(B%%k^),=SQRT^(D%%k^),=^(J%%k - B13^)^^2 >>t%%j.csv
where the omitted file path is 38 characters long (I don't think I'm hitting the line limits, but just in case this is the problem). This is a single line in my .bat file, shown here as multiple lines just to make things more readable.
The output is mostly correct, except that where I have ^^2, it just becomes 2 (so I have =(E1)2 and =(J1-B13)2. If I omit the Indirect.Ext text, and just have
echo =%%k-16,a1,b1,^=C%%k/1000,^=D%%k-B%%k,^=ABS^(E%%k^),^=(E%%k^)^^2,=^(B%%k-B10^),=Sqrt^(B%%k^),=SQRT^(D%%k^),=^(J%%k - B13^)^^2 >>t%%j.csv
it prints correctly, so the relevant comments show as =(E1)^2 and =(J1-B13)^2, which is what I am after.
I've not had any luck finding an answer, everything I have found just points to using ^^ to get echo to return ^. I cannot break this command into multiple lines, I need it to be a single row in csv format.
Any suggestions for a fix much appreciated, I only really need to use this for a week or so, don't need an elegant solution, just one that works. - I'm very new to bat scripts (and indeed programming in general), will keep trying different ideas in the mean time.
It's only the exclamation mark that creates the problems for you.
If at least one ! is in your line (and delayed expansion is enabled), then a second caret escape phase will be started.
In this phase quotes aren't regarded, only carets.
A small test
setlocal EnableDelayedExpansion
echo one^1
echo two^^2
echo two^^2 With exclam!
echo five^^^^^& With exclam!
Output
one1
two^2
two2 With exclam
four^& With exclam
So in your sample, you need five carets.
Four to create one caret and the last one to escape the ), as the escape of the special character is only once required.
Not sure what your specific problem is but you can use a trick in Windows to emulate echo -n (echo without a newline).
The commands:
<nul: >file.csv set /p junk=first field
<nul: >>file.csv set /p junk=,second field
>>file.csv echo ,third field
will result in a single line:
first field,second field,third field
That may make it easier for you to avoid the specific problem and, as a bonus, clean up your script so it's a little more readable (such as one field per script line).
It works because set /p var=prompt is the input command. It first outputs prompt without a newline then waits for the user to enter something, assigning it to the var environment variable.
By getting input from nul:, you basically give it an empty string so it doesn't wait. The prompt is output to file.csv without the newline.
In any case, for something this complex, I'd be bypassing cmd.exe for something a little more powerful such as the UNIX text processing tools under CygWin or MinGW (which require installation but are well worth it), or even VBScript scripts (which should be on Windows by default), where you can more easily control the output.
I'm working on a Windows batch file that will bcp three text files into SQL Server. If something goes wrong in production, I want to be able to override the file names. So I'm thinking of doing something like this.
bcp.exe MyDB..MyTable1 in %1 -SMyServer -T -c -m0
bcp.exe MyDB..MyTable2 in %2 -SMyServer -T -c -m0
bcp.exe MyDB..MyTable3 in %3 -SMyServer -T -c -m0
I would like to be able to enter default names for all three files, to be used if the positional parameters are not supplied. The idea would be either to execute
myjob.bat
with no parameters, and have it use the defaults, or execute
myjob.bat "c:\myfile1" "c:\myfile2" "c:\myfile3"
and have it use those files. I haven't been able to figure out how to tell if %1, %2 and %3 exist and/or are null. I also don't know how to set those values conditionally. Is this possible? Any suggestions would be appreciated.
To test for the existence of a command line paramater, use empty brackets:
IF [%1]==[] echo Value Missing
or
IF [%1] EQU [] echo Value Missing
The SS64 page on IF will help you here. Under "Does %1 exist?".
You can't set a positional parameter, so what you should do is do something like
SET MYVAR=%1
You can then re-set MYVAR based on its contents.
The right thing would be to use a "if defined" statement, which is used to test for the existence of a variable. For example:
IF DEFINED somevariable echo Value exists
In this particular case, the negative form should be used:
IF NOT DEFINED somevariable echo Value missing
PS: the variable name should be used without "%" caracters.
Both answers given are correct, but I do mine a little different. You might want to consider a couple things...
Start the batch with:
SetLocal
and end it with
EndLocal
This will keep all your 'SETs" to be only valid during the current session, and will not leave vars left around named like "FileName1" or any other variables you set during the run, that could interfere with the next run of the batch file. So, you can do something like:
IF "%1"=="" SET FileName1=c:\file1.txt
The other trick is if you only provide 1, or 2 parameters, use the SHIFT command to move them, so the one you are looking for is ALWAYS at %1...
For example, process the first parameter, shift them, and then do it again. This way, you are not hard-coding %1, %2, %3, etc...
The Windows batch processor is much more powerful than people give it credit for.. I've done some crazy stuff with it, including calculating yesterday's date, even across month and year boundaries including Leap Year, and localization, etc.
If you really want to get creative, you can call functions in the batch processor... But that's really for a different discussion... :)
Oh, and don't name your batch files .bat either.. They are .cmd's now.. heh..
Hope this helps.
rem set defaults:
set filename1="c:\file1.txt"
set filename2="c:\file2.txt"
set filename3="c:\file3.txt"
rem set parameters:
IF NOT "a%1"=="a" (set filename1="%1")
IF NOT "a%2"=="a" (set filename2="%2")
IF NOT "a%3"=="a" (set filename1="%3")
echo %filename1%, %filename2%, %filename3%
Be careful with quotation characters though, you may or may not need them in your variables.
Late answer, but currently the accepted one is at least suboptimal.
Using quotes is ALWAYS better than using any other characters to enclose %1.
Because when %1 contains spaces or special characters like &, the IF [%1] == simply stops with a syntax error.
But for the case that %1 contains quotes, like in myBatch.bat "my file.txt", a simple IF "%1" == "" would fail.
But as you can't know if quotes are used or not, there is the syntax %~1, this removes enclosing quotes when necessary.
Therefore, the code should look like
set "file1=%~1"
IF "%~1"=="" set "file1=default file"
type "%file1%" --- always enclose your variables in quotes
If you have to handle stranger and nastier arguments like myBatch.bat "This & will "^&crash
Then take a look at SO:How to receive even the strangest command line parameters?
