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.

First-time OpenID users will be automatically assigned a username which can be changed after signing in.
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.

Use the hold space to preserve lines until data is needed.
List packages and their disk usage in decreasing order. This uses the "Installed-Size" from the package metadata. It may differ from the actual used space, because e.g. data files (think of databases) or log files may take additional space.
The sort utility is well used, but sometimes you want a little chaos. This will randomize the lines of a text file.
BTW, on OS X there is no
| sort -R
option! There is also no
| shuf
These are only in the newer GNU core...
This is also faster than the alternate of:
| awk 'BEGIN { srand() } { print rand() "\t" $0 }' | sort -n | cut -f2-
A little bit smaller, faster and should handle files with special characters in the name.
This can be much faster than downloading one or both trees to a common servers and comparing the files there. After, only those files could be copied down for deeper comparison if needed.
Based on the MrMerry one, just add some visuals to differentiate files and directories
Based on the MrMerry one, just add some visuals and sort directory and files
"cut" the user names from /etc/passwd and then running a loop over them.
Check which files are opened by Firefox then sort by largest size (in MB). You can see all files opened by just replacing grep to "/". Useful if you'd like to debug and check which extensions or files are taking too much memory resources in Firefox.
This command will find the biggest files recursively under a certain directory, no matter if they are too many. If you try the regular commands ("find -type f -exec ls -laSr {} +" or "find -type f -print0 | xargs -0 ls -laSr") the sorting won't be correct because of command line arguments limit.
This command won't use command line arguments to sort the files and will display the sorted list correctly.
This one will work a little better, the regular expressions it is not 100% accurate for XML parsing but it will suffice any XML valid document for sure.
This will mv all your mp3 files in the current directory to $ARTIST/$ALBUM/$NAME.mp3
Make sure not to use sudo - as some weird things can happen if the mp3 file doesn't have id3 tags.
Save the script as: sort_file
Usage: sort_file < sort_me.csv > out_file.csv
This script was originally posted by Admiral Beotch in LinuxQuestions.org on the Linux-Software forum.
I modified this script to make it more portable.
Found this one little more for me. This one removes the perl dependency (from command 2535).
Source for command : http://www.earthinfo.org/linux-disk-usage-sorted-by-size-and-human-readable/
using mb it's still readable;) a symbol variation
$ du -ms {,.[^.]}* | sort -nk1
somewhat faster version to see the size of our directories. Size will be in Kilo Bytes. to view smallest first change '-k1nr' to '-k1n'.
This commands will make it easier to select only common items between two files being compared. If your lines start with things other than lowercase a-z, adjust this Regex appropriately. Number of lines in the output has been set to no more than 10000, and should be adjusted as needed.
This set of commands was very convenient for me when I was preparing some xml files for typesetting a book. I wanted to check what styles I had to prepare but coudn't remember all tags that I used. This one saved me from error-prone browsing of all my files. It should be also useful if one tries to process xml files with xsl, when using own xml application.
This appends a random number as a first filed of all lines in SOMEFILE then sorts by the first column and finally cuts of the random numbers.
