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.

You can sign-in using OpenID credentials, or register a traditional username and password.

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

UpGuard checks and validates configurations for every major OS, network device, and cloud provider.

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.

This command will loop until the process no longer exists, calling closemainwindow() this is as if the user clicked the close window x in the upper right hand corner and gives the user an opportunity to save work in many applications like notepad and other things. The $'s are escaped for Cygwin, if you want to run the same command from the RUN box or cmd.exe shell then just unescape the $'s:

powershell -Command "while ($true){Try{$process=Get-Process calc -ErrorAction Stop}Catch [Microsoft.PowerShell.Commands.ProcessCommandException]{break;}if ($process) {$whateva=$process.CloseMainWindow()}else {break;}Start-Sleep -m 500}"

just set macdst to the mac address of the system

you wish to wake up, the macsrc is optional but helps

use tcpreplay to broadcast or wireshark to view

Functions: echo ssh

Tested on Windows 8 w/SSH, Cygwin - it can be tricky to quote if you dont use the $(..) syntax to echo it back out

perl -M URI::Escape -lne 'print uri_unescape($_)'
echo "btrfs checksum error(s) on: " && grep "btrfs: checksum error at logical" /var/log/messages | sed -e 's/^.*\( dev .*\)\(, sector.*\)\(path\: .*\))/\t\1, \3/' | sort | uniq

Filter entries in OpenSuse /var/log/messages like:

Functions: echo sed

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. This is complete command (best without entity encoding):

echo -e '\x2Helo folks\t!\r' | sed "y/\x0\x1\x2\x3\x4\x5\x6\x7\x8\x9\xA\xB\xC\xD\xE\xF\x10\x11\x12\x13\x14\x15\x16\x17\x18\x19\x1A\x1B\x1C\x1D\x1E\x1F\x20/&#9216;&#9217;&#9218;&#9219;&#9220;&#9221;&#9222;&#9223;&#9224;&#9225;&#9226;&#9227;&#9228;&#9229;&#9230;&#9231;&#9232;&#9233;&#9234;&#9235;&#9236;&#9237;&#9238;&#9239;&#9240;&#9241;&#9242;&#9243;&#9244;&#9245;&#9246;&#9247;&#9248;/"

Functions: perl

Converts control codes and spaces (ASCII code ≤ 32) to visible Unicode Control Pictures, U+2400 ? U+2420. Skips \n characters, which is probably a good thing.
