Pull out only first field of ps command ( in Perl ) PERL RUN COMMAND

[tweetiebirds]

Hi,

I want to filter out only the first column of the output of the ps -ae
command in Perl using
perl run-command.

I.e using perl -pi -e etc....

Anyone know how to do this ?

I do NOT want to use UNIX cut.

thanks

Did you try something? Can you post what you tried, so we can help you?

I'd suggest a reading of 'perldoc perlrun'. You'll probably want to use
a something like:

ps -ae | perl -lane '<insert code here>'

I'm going to leave the code itself as an exercise for you, and if you
have problems post what you tried and I'll be happy to help you
understand it better.
