cut question - UNIX for Dummies Questions & Answers

knc9233 · #1 02-16-2007

Code:

#!/bin/bash

echo "UserName  PID     Command"
ps -ef > ps.temp
grep '^[a-z]\{2,3\}[0-9]\{4\}' ps.temp > ps.temp2
cut -f1,2,8 ps.temp2
rm ps.temp*

I am having some problems with the cut command. I only want to display the UID (field 1), PID(field 2), and Command(field 8). Right now the whole ps -ef line is display. Please help?!

Why don't you just use the formatted output ps command?

eg:

Code:

ps -eo uid,pid,args

the uid displays as the number and not the username...how do i get the username instead of the number?

Now now

(2) No negative comments about others or impolite remarks. Be patient.

That's why for some of the questions that would be easily found, I'll post "man find" for example or "a google search found".
