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.

What others think

strings -f sample.txt

Is similar to:

grep -H . sample.txt

Urgh! This ignores blank lines, short lines, anything in UTF8.

You're lucky to get out the file you put in.

Thanks. Your command works for non-ASCII encodings without change too, with 'strings' one has to add an option:

strings -fe S sample.txt

S = single-8-bit-byte characters

grep -H '.\|' sample.txt

doesn't omit empty lines
