ksh help: list following 3 lines after find a keyword

Hanry Zhou — Thu, 05 Jun 2014 09:22:46 GMT

I have a large files, and some lines include a keyword that I am looking for. Further, I wanted to list next 3 lines following the line that includes the keywork.

Thank you very much for your help!

Get yourself gnu grep and just use -A3.

In case your site doesn't allow open source software outside of hp.com, you can use awk:

awk '/pattern/{print;getline;print;getline;print;getline;print}' filename

where pattern is whatever keyword(s) you are looking for, and filename is the name of the file.

If you like cryptic commands you can use sed:

sed -e '
/pattern/ {
n; n; n; p
}
d'

Note: sed uses REs and awk uses EREs.
