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/

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.

ifconfig | perl -nle'/dr:(\S+)/ && print $1'

User: xsawyerx
Functions: ifconfig perl
11

Fetches the IPs and ONLY the IPs from ifconfig. Simplest, shortest, cleanest.

Perl is too good to be true...

(P.S.: credit should go to Peteris Krumins at catonmat.net)

function sshdel { perl -i -n -e "print unless (\$. == $1)" ~/.ssh/known_hosts; }
2009-02-03 16:20:50
User: xsawyerx
Functions: perl
-1

sometimes you got conflicts using SSH (host changing ip, ip now belongs to a different machine) and you need to edit the file and remove the offending line from known_hosts. this does it much easier.

tar czv file1 file2 folder1 | ssh user@server tar zxv -C /destination
2009-01-29 10:38:26
User: xsawyerx
Functions: ssh tar
13

it compresses the files and folders to stdout, secure copies it to the server's stdin and runs tar there to extract the input and output to whatever destination using -C. if you emit "-C /destination", it will extract it to the home folder of the user, much like `scp file user@server:`.

the "v" in the tar command can be removed for no verbosity.

svn status |grep '\?' |awk '{print $2}'| xargs svn add
2009-01-29 10:33:22
User: xsawyerx
Functions: xargs
13

checks which files are not under version control, fetches the names and runs them through "svn add". WARNING: doesn't work with white spaces.

perl -pi.bk -e's/foo/bar/g' file1 file2 fileN
2009-01-29 09:51:11
User: xsawyerx
Functions: perl
10

the addition of ".bk" to the regular "pie" idiom makes perl create a backup of every file with the extension ".bk", in case it b0rks something and you want it back

perl -pi -e's/foo/bar/g' file1 file2 fileN
2009-01-29 09:47:01
User: xsawyerx

The "g" at the end is for global, meaning replace all occurrences and not just the first one.
