What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

Universal configuration monitoring and system of record for IT.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Print out "string" between "match1" and "match2"

But who knows to delete the rest of the lines?

I want only "string".

What others think

Not entirely sure what you're wanting, this maybe?

sed -e 's/^.*\(string\).*$/\1/'
Comment by TheMightyBuzzard 315 weeks and 3 days ago

This should be what you're looking for. Only prints lines with match1 and match2 in them, and only the section between the two matches.

sed -ne 's/.*\(match1.*match2\).*/\1/p'

or, a bit easier:

egrep -o 'match1.*match2'

Works with standard grep here, too, but YMMV.

If you don't know what you're after, why are you posting to CLF? This isn't a support forum, but a repository of the best commands on the web. BTW:

echo "string" | awk '/match1/,/match2/'
Comment by atoponce 315 weeks and 3 days ago

I got it:

sed -n '/match1/,/match2/p' file.txt | sed -e '/match1/d' | sed -e '/match2/d'
