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.

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.

buf myfile.txt

This is useful when you are making small but frequent changes to a file. It keeps things organised and clear for another administrator to see what changed and at what time. An overview of changes can be deduced using a simple:

ls -ltr
function cp_mp3_to { PID=`pidof audacious2`; FILEPATH=`lsof -p $PID| grep mp3| sed s/[^\/]*//`; cp "$FILEPATH" "$1"; }

Functions: cp grep sed
Tags: copy mp3

Maybe it could work for any music player if you change "audacious2" with the string you see in `ps aux` for your player. Needs testing in different systems.

Functions: cp find xargs

This command will a particular folder-name recursively found under the src-path-to-search to the dest-path-to-copy retaining the folder structure

p=~/.config/chromium/zed; cp -r ~/.config/chromium/Default $p && echo "chromium-browser --user-data-dir=$p" && chromium-browser --user-data-dir=$p;
2010-11-08 02:45:29
User: zed
Functions: cp echo

Change the value of p to match the path where you wish to create the profile.

To run it again in the future, use the parameter --user-data-dir (which gets echoed to you when run):

chromium-browser --user-data-dir=/path/to/your/

Quick Functions:

# create a new chromium profile

new-chromium-profile() { p=~/.config/chromium/$1; cp -r ~/.config/chromium/Default $p && echo "chromium-browser --user-data-dir=$p" && chromium-browser --user-data-dir=$p; }

# runs a chromium profile

run-chromium-profile() { chromium-browser --user-data-dir=~/.config/chromium/$1; }

Functions: cp
Tags: git zip dropbox

If like me you do a lot of front-end coding and you have a lot of clients that asks you some little modifications, then you send the modifications back to them in a zip file while ignoring the .git folder and .gitignore file, then copy this zip into your dropbox and send it back to them. They find out a new bug so, rince and repeat? You get the picture. It can be quite tedious.

Today I needed to choose an icon for an app. My simpler way: put all of /usr/share/icons in myicons folder and brows'em with nautilus. Then rm -r 'ed the entire dir.

find . -type f -iname '*.mp3' -exec cp {} ~/mp3/ \;
2009-12-09 00:19:14
User: SlimG
Functions: cp find

This command copies all filenames in the current dir and subdirs that end in .mp3 regardless of case (also matches .MP3 .mP3 and .Mp3)

It copies all the files to the "mp3" folder in your home directory.

If you want to see the files that are beeing copied, replace "cp {}" with "cp -v {}"

find . -iname '*.mp3' -type f -print0 | xargs -I{} -0 cp {} </path>

No problem with word splitting. That should works on many Unix likes.

I used this command to recursively gather all mp3 files that were previously imported into their own directories (sorted by band name) in Songbird.

User: polaco
Functions: cp date
Tags: backup copy date

This script creates date based backups of the files. It copies the files to the same place the original ones are but with an additional extension that is the timestamp of the copy on the following format: YearMonthDay-HourMinuteSecond

for file in <filename>; do cp $file{,.bak} && sed 's/old/new/g' $file.bak > $file; done
2009-08-25 16:19:45
User: Cenobite
Functions: cp file sed
Tags: bash sed

"&&" runs sed if and only if the backup completed and /bin/cp exited cleanly. Works for multiple files; just specify multiple filenames (or glob). Use -v switch for cp to play it safe.

cp -pr olddirectory newdirectory
2009-08-22 22:11:24
User: stanishjohnd
Functions: cp

cp options:

-p will preserve the file mode, ownership, and timestamps

-r will copy files recursively

also, if you want to keep symlinks in addition to the above: use the -a/--archive option
