How do I extract a particular column from text (like the output of ps)?

summary.md

awk has a command for this:

$ awk '{print $2}' <filename>

You can, of course, also pipe in text output from another program:

$ who
noah     console  Oct 21 14:06 
noah     ttys000  Oct 23 13:08 
noah     ttys001  Oct 23 14:00 
noah     ttys004  Oct 22 21:48 
$ who | awk '{print $2}'
console
ttys000
ttys001
ttys004
