the title might be slightly confusing but what I need is a method to hand over pre-configured parameters to a batchfile on windows commandline.
The batchflie executes several progams (openssl) that need interactive input. To avoid this, I wrote all necessary input parameters to a textflie and now try to do something like:
type parameters.txt | mybatchfile.bat
Unfortunately this doesn't work.
Is there a way to do this?
Passing text into stdin of interactive prompts of console programs sometimes works, but needs to be done on single line of specific program. Tested way for SSH communication in batch file:
some batch code
echo n| plink.exe -pw "somepassword" root#somehost someremotecommand
some batch code

The windows API provides GetCommandLine() which returns the cooked command line used to start a process.
For instance, if a console application is started with the command:
MyProg.exe > OutputHere
The command line seen by MyProg.exe will not include the portion
> OutputHere
I'd like to somehow get the command line exactly as it was. Is this possible ? and if yes, how ?
Suggestions in C and/or plain (no objects) Delphi greatly appreciated. Creative solutions welcome (hopefully, not requiring ring 0 code.)
Thank you very much for your help.
NOTE: I can tell if the input/output, etc has been redirected but, that is not what I'm looking for. I need the original/uncooked command line.
The redirection or piping of stdin, stdout and stderr is handled the command interpreter, typically cmd.exe. The interpreter parses the command and creates the necessary files and pipes, and then creates the one or more processes needed to implement your command.
The processes that are created have no knowledge of the original command, they only get that part of the command that is not related to piping and redirection.
So what you are trying to do is not possible, at least within your process. The only thing that knows the original command is the command interpreter.
Whether or not you can retrieve the full command line including the pipe commands depends on whether your start the program in a command window or for example using the "Run" command from the Start menu. If you use the "Run" command from the Start menu GetCommandLine actually retrieves the full command line including the redirection commands, but redirection does not work as it seems to be a feature of CMD.EXE.
As others have pointed out, what are you trying to achieve here / why do you need to capture the redirection commands?
I have a program that I work with, that has an onboard lua compiler to allow for custom written actions.
Since the tool itself is very limited, especially if it goes for complex reactions over networks, I want to use Powershell over lua.
Methods like os.execute() or io.popen() use the standard command line from windows and not Powershell.
Is there a way to use Powershell with lua?
I tried to write a command line script with the Powershell editor and run this script with os.execute, but it opens it as a textfile, it would be better to write the commands directly in lua but if there is no other way, executing a Powershell script directly would also be fine. (In Windows itself you can execute the script with right mouse "click/Execute with Powershell")
-- You can generate PowerShell script at run-time
local script = [[
Write-Host "Hello, World!"
]]
-- Now create powershell process and feed your script to its stdin
local pipe = io.popen("powershell -command -", "w")
pipe:write(script)
pipe:close()
Your description of the problem makes it sound like you're using a command such as os.execute("powershellscript.ps1"), and that call invokes cmd.exe with your string as the proposed command line. Normally, Windows will open a .PS1 file for editing; this was a deliberate decision for safety. Instead, try altering the os.execute() command to explicitly call PS: os.execute("powershell.exe -file powershellscript.ps1"). If you need to pass parameters to your script, enclose them in {}. See https://msdn.microsoft.com/en-us/powershell/scripting/core-powershell/console/powershell.exe-command-line-help for more info on invoking PowerShell from the command line.
ftp ipaddress
bin
hash
cd path
get filename
quit
i want these line to be executed in a shell script only first line is executing after entering username and password the rest line are not executing and the control is stuck at ftp> prompt
Once your script invokes the program ftp, the shell loses control until the ftp program finishes. So you need to use some new technique. One way is with the program expect, which you can get a hint about here: https://stackoverflow.com/a/12598169/4323 . Another way is to use a more "scriptable" FTP client, such as lftp on Linux, which has specific features to enable the sort of scripted use you're going for.
You need to use a non-interactive FTP client if you want to do this in a script rather than an interactive shell. ncftp is one you could check out.
Or you can use a shell "here" document:
#!/bin/bash
ftp -in <<EOS
user pswd
bin
hash
cd path
get filename
quit
EOS
The here document sends everything via the open program's stdin, just as if you typed it in at the command line. Note that ftp clients can be finicky and each one seems to have it's own set of gotchas, so some experimentation and use of man ftp will likely be required.
Looks like this has come up before on Stackoverflow, you might want to read through

What is the best WinAPI function to use when you only want to run a simple shell command like hg > test.txt?
To simply run a file, then ShellExecute() and CreateProcess() are the best options.
As you want to redirect output to a file/run a shell command, it complicates things...
Output redirection is a feature of the command prompt, and as such, the command you want to run needs to be passed to cmd.exe (on NT/XP+) passing /c and your command as the parameters (either ShellExecute or CreateProcess will do).
cmd /c "ipconfig >c:\debug\blah.txt"
The best way however is to use CreateProcess() and create your own pipes to talk to the stdin and stdout of the program (This is all cmd does internally)
You could use ShellExecute(), but why not try system() first? I am not so sure that ShellExecute() can actually do piping or redirection. There is also CreateProcess(), but that requires a bit more work. CreateProcess() gives you the best control, though.
There are two ways of issuing commands: the Windows Shell way, and the command line way.
Windows Shell issues commands by executing verbs on files. Verbs are associated with file types in the registry. Examples of common verbs are Open and Print. The WinAPI to use for this is ShellExecute. Windows Shell does not help you pipe the output of a process to a file. You can do it using CreateProcess, but it is a little bit involved.
The command line way is to use the system function.
Is there a way, to send commands to another command-line program?
'Cause i have a special command-line program, but I can't send commands to it using syntax like program.exe something_to_do
the program executes something like this: ("here syntax" is where i want to input text to and also enter to start)
TheWhateverCommandLineProgram
Version 1.1
Give an option: "here syntax"
the program in code looks something like this:
echo TheWhateverCommandLineProgram
echo Version 1.1
Set opt=
set /p opt=Give an option:
if %opt%==command1 goto com1
if %opt%==command2 goto com2
...
Well, i guess so cause it wasnt me who made it (btw: off course its not called TheWhateverCommandLineProgram)
If you just want to give keyboard input to a commandline program you can just use echo and pipe it:
echo some text | program.exe
If you need more lines, then write them to a file and use input redirection:
echo one line > file
echo second line >> file
program.exe < file
I'm not 100% sure I understand what you're looking for. Here's two options:
You have two windows, each running a batch program. Let's say they are called myscript1.bat and myscript2.bat. You want to send a set of commands from myscript1.bat to be executed by myscript2.bat
You have a single batch script named myscript.bat, which executes a single program named program.exe. You want program.exe to execute some commands, or do some something.
Are either of these what you're looking for? Here's some idea:
Make myscript1.bat create a third file, mycommands.bat. Once myscript2.bat sees the file mycommands.bat exists, it will execute it and delete it. (Wow. Lame.)
Use Windows Scripting Host command (it's built in to Windows since Win2K) or Powershell (usually on most computers nowadays, if they have been updated). Either of these can send keystrokes to another program. Using those keystrokes, you can control the other program.
In what form does the other program take input? From the command prompt?
If the latter then I recommend Autohotkey: http://www.autohotkey.com/
You can use Autohotkey as a bridge and it will send the command as keypresses to the window of the other batch file.
You can ask for help in their forum. They are quite helpful.
