The equivalent of running in a Terminal is to run it in a shell. Try the following code:

OSSUnixSubprocess new
�� �� �� �� command: '/bin/bash';
�� �� �� �� arguments: #('-c' 'ls /');
�� �� �� �� redirectStdout;
�� �� �� �� runAndWaitOnExitDo: [ :process :outString�� |
�� �� �� �� �� �� �� �� outString inspect
�� �� �� �� ].

OSSUnixSubprocess new
�� �� �� �� command: '/bin/bash';
�� �� �� �� arguments: #('-c' 'ls / | grep bin');
�� �� �� �� redirectStdout;
�� �� �� �� runAndWaitOnExitDo: [ :process :outString�� |
�� �� �� �� �� �� �� �� outString inspect
�� �� �� �� ].

You���ll need to be careful to properly shell escape the shell command arguments if they are not hard coded (especially things like file names from users). HTH. ���Yanni

Hi

I tried something similar on (X)ubuntu using this: 

OSSUnixSubprocess new
	command: '/bin/ls';
	arguments: #('-la' '/tmp/' '|' '/usr/bin/grep unix');
	redirectStdout;
	runAndWaitOnExitDo: [ :process :outString  |
		outString inspect
	]


and looking at the output in xtrerm I got a message like this: 

/bin/ls: cannot access '|': No such file or directory
/bin/ls: cannot access '/usr/bin/grep unix': No such file or directory.


So I think it regards anything after the first item in the arguments as a file or directory.

This means you will have to write a bash script instead. So I wrote a script called my_grep:

#!/bin/bash
cd $1
ls -la | grep unix

and called it with: 

OSSUnixSubprocess new
	command: '/tmp/my_grep';
	arguments: #('/tmp');
	redirectStdout;
	runAndWaitOnExitDo: [ :process :outString  |
		outString inspect
	]

and it worked.
