I'd like to get the first line after a line containing "pm EDT".
I've read the man pages for grep and googled but to no avail.
I'm using Xcode4 with OS 10.7.4
Use two greps -
grep -A1 'pm EDT' whateverfile
That will get you the line you're looking for, AND the line after
Then, use another grep to find lines that don't match 'pm EDT'
grep -v 'pm EDT'
Stick them all one one line with a pipe:
grep -A1 'pm EDT' whateverfile | grep -v 'pm EDT'
