Thats right. You have to put the result in a file and then afterwards read the file. ls uname -r > file.txt The integer is the result code of the execution. It contains information if the execution was successful.

You may also use a TProcess object:

Here you have a tutorial with some examples:

You already quoted where you find a solution for this below:

It's not a simple "result value", but you'll need to do a bit of work.

Johan, READ THE ENTIRE MESSAGE THAT YOU ARE QUOTING. You might be used to top-posting, but the convention on this ML is bottom-quoting and those links aren't just bits of somebody's sig, they contain the answer to your question.

Apologies to everybody else for top-quoting and "shouting", but I think there's a possibility that the OP's missed the message due to unfamiliarity with the medium.

First, please post the actual command line to execute and if where (what directory) matters. E.g. it matters for ls, but not for uname.

Since

>> ls uname -r > file.txt

this is a bit too vague and ambiguous.
