hi all,

the following doesn't seem to give the correct output when used as an alias... is the syntax correct?

alias psf "ps -auxww | grep \!:1 | grep -v grep | awk '{print $2}'"

[Moonray]

Yes, it is correct for tcsh.

thanks for the reply moonray.

thing is it doesn't work when the commands are combined into an alias. the grep results don't seem to be awk'ed.

Welcome to the hideous world of tcsh quoting. Not a nice place to land. Maybe this will help you out...

alias psf 'ps -auxww | grep \!:1 | grep -v grep | awk '\\''{print $2}'\\'' '

(Yep, *lots* of single quotes in there. Please cut and paste when you're tying it out!) I wish to plead "not guilty" to creating such a monstrous construction: I just hunted around in /usr/share/tcsh/examples/aliases for a similar beast and there it was...

Cheers,
Paul

Oops yes. Sorry I didn't pay attention to that detail. The reason is that the shell expands the $2 if it is enclosed by double (or no) quotes instead of passing it to awk. Paul McCann's version should work fine, or if you want the double quotes, use:

alias psf "ps -auxww | grep \!:1 | grep -v grep | awk '{print "'$2'"}'"

or if you want less quotes:

alias psf ps -auxww | grep \!:1 | grep -v grep | awk '{print $2}'

Hope that helps.
