return value of a system call?
Is it possible to save the return value of system call to a variable.
I'm using system to call another script, written by someone else if python, that returns a variable that I need.
I know how to sent the STDOUT to null but I want to retain it for use inside my script. Is this possible? Thanks
Well just wanted to respond that I found that answer to my question :)
You can use backquotes to Invoke System Commands
for example: $myname = `whoami`;
be aware the you will almost always have to chop that variable after doing this because of the newlines appended to the output of normal system calls.
