Above command works fine. But I just dont want to use single quotes in awk statement such that i can avoid the usage of escape character \ and my command looks pretty neat.
why are external commands ('who am i' and 'awk') to get the user name?
Doesn't python provide native instrumentation to get this info?
Cannot you get the user name from the environment variable from within python?

I think the user wants the associated terminal... I that so?

Vbe: yes you are right. These commands are executed in remote servers terminals.

You should still be able to use python commands - either getting it from the environment variable, or there may be a tty package.

As mirni said, if you're using a command string with that awk script you're going to need to escape something to get it to work. You could use a script file (either for the awk script or the whole thing), but it seems rather like overkill for a purely cosmetic issue.

Fine. Thank you all.
conclusion: Dont overkill for purely cosmetic issue (carloM). I would better use escape characters.
