Extract all archives from current folder, each archive in its own folder.

Magic line will extract almost all possible archives from current folder in its own folders. Don't forget to change USER name in sudo command. sed is used to create names for folders from archive names w/o extension. You can test sed expression, used in this command: arg='war.lan.net' ; x=$(echo $arg|sed 's/$.*$\..*/\1/') ; echo $x If some archives can't be extracted, install packages: apt-get install p7zip-full p7zip-rar Hope this will save a lot of your time. Enjoy.

Revoke an existing user's group memberships and add another user to those same groups,

Assuming a convention looking group file, this command will eject oldspiderman from the leagueofsuperfriends group and add newspiderman: oldspiderman:x:551: aquaman:x:552: superman:x:553: newspiderman:x:554: leagueofsuperfriends:x:1000:superman,oldspiderman,superman,aquaman

Fetch all GPG keys that are currently missing in your keyring

The original command doesn't work for me - does something weird with sed (-r) and xargs (-i) with underscores all over... This one works in OSX Lion. I haven't tested it anywhere else, but if you have bash, gpg and perl, it should work. Show Sample Output

Pronounce an English word using Merriam-Webster.com

Updated to the new version of the MW webpage (seems MW does not use cougar anymore, so the other commands do not work nowadays), and using Xidel to parse the page with a html parser instead regex. Example usage: pronounce onomatopoetic I'm not sure how well Xidel works with binary streams (although it seems to work great in tests), so using wget to download the actual wav file might be safer, i.e.: pronounce(){ wget -qO- $(xidel "http://www.m-w.com/dictionary/$*" -f "replace(css('.au')[1]/@onclick,\".*'([^']+)', *'([^']+)'.*\", '/audio.php?file=\$1&word=\$2')" -e 'css("embed")[1]/@src') | aplay -q;} Xidel is not a standard cli tool and has to be downloaded from xidel.sourceforge.net

Dropbox login using only curl, sed and bash

Use the command line to log into Dropbox. You have to replace me@yahoo.com with your Dropbox email (note the URL-encoding of "@" as %40). Also replace my_passwd with your Dropbox password. (Note: special characters in your password (such as #) must be url-encoded. You will get a cookie (stored in file "cookie") that you can use for subsequent curl operations to dropbox, for example curl -b cookie https://www.dropbox.com/home. Debug note: If you want to see what data curl posts, use curl's --trace-ascii flag. Show Sample Output

link=https://www.dropbox.com/login ; curl -b a -c cookie -d "t=$(curl -c a $link | sed -rn 's/.*TOKEN: "([^"]*).*/\1/p')&login_email=me%40yahoo.com&login_password=my_passwd" $link

A command to find and replace text within conf files in a single directory.

Not better, but more lightweight (sed instead of perl). Above command is reduced due to length restriction of less than 256 characters and entity encoding of "Save" command on this page.

easily find megabyte eating files or directories

This is easy to type if you are looking for a few (hundred) "missing" megabytes (and don't mind the occasional K slipping in)... A variation without false positives and also finding gigabytes (but - depending on your keyboard setup - more painful to type): $du -hs *|grep -P '^(\d|,)+(M|G)'|sort -n (NOTE: you might want to replace the ',' according to your locale!) Don't forget that you can modify the globbing as needed! (e.g. '.[^\.]* *' to include hidden files and directories (w/ bash)) in its core similar to: http://www.commandlinefu.com/commands/view/706/show-sorted-list-of-files-with-sizes-more-than-1mb-in-the-current-dir

uniq without pre-sorting

Reads stdin, and outputs each line only once - without sorting ahead of time. This does use more memory than your system's sort utility.

Dump a web page

Useful to browse dangerous web sites.

Create a single-use TCP (or UDP) proxy

Redirect the local port 2000 to the remote port 3000. The same but UDP: $ nc -u -l -p 2000 -c "nc -u example.org 3000" It may be used to "convert" TCP client to UDP server (or viceversa): $ nc -l -p 2000 -c "nc -u example.org 3000"

Search google and show only urls

Get the first 10 google results form a querry, but showing only the urls from the results. Use + to search diferent terms, ex: commandlinefu+google .

mysql DB size

Join lines and separate with spaces

Read vmargs.txt, which is a text file that could either be DOS-style (\r\n) or UNIX-style (\n) line endings and join the lines with a space separator. Can this be shortened/made more elegant?

Check a directory of PNG files for errors

Useful for checking if a large number of PNG files was downloaded successfully by verifying the built-in CRC checksum. For incomplete files, the command will print: "00002309.png EOF while reading IDAT data ERROR: 00002309.png" The process is very fast; checking 21,000 files of 5MB in size took only five minutes on a 2011 Intel mobile dual-core.

Get the current svn branch/tag (Good for PS1/PROMPT_COMMAND cases)

uses just one sed

Get full URL via http://untr.im/api/ajax/api

Get full url via untr.im
