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.
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.

A wrapper around ssh to automatically provide logging and session handling.
This function runs ssh, which runs screen, which runs script.
.
The logs and the screen session are stored on the server.
This means you can leave a session running and re-attach to it later, or from another machine.
.
.
Requirements:
* Log sessions on a remote server
* Transparent - nothing extra to type
* No installation - nothing to copy to the server beforehand
.
Features:
* Function wrapper delegating to ssh
- so nothing to remember
- uses .ssh/config as expected
- passes your command line option to ssh
* Self-contained: no scripts to install on the server
* Uses screen(1), so is:
- detachable
- re-attachable
- shareable
* Records session using script(1)
* Configurable log file location, which may contain variables or whitespace
L="$HOME" # local variable
L="\$HOME" # server variable
L="some space"
.
Limitations:
* Log dir/file may not contain '~' (which would require eval on the server)
.
.
The sessions are named by the local user connecting to the server.
Therefore if you detach and re-run the same command you will reconnect to your original session.
If you want to connect/share another's session simply run:
USER=bob ssh [email protected]
.
The command above is stripped down to an absolute minimum.
A fully expanded and annotated version is available as a Gist (git pastebin):
https://gist.github.com/flatcap/3c42326abeb1197ee714
.
If you want to add timing info to script, change the command to:
ssh(){ L="\$HOME/logs/$(date +%F_%H:%M)-$USER";/usr/bin/ssh -t "[email protected]" "mkdir -p \"${L%/*}\";screen -xRRS $USER script --timing=\"$L-timing\" -f \"$L\"";}
Downloads Bluetack's level 1 IP blocklist in .p2p format, suitable for various Bittorrent clients.
A quick alias I use right before logging into a server so that I have a log of the transactions as well as the ability to re-connect from another computer. Useful for when your boss says "what commands did you run again on that server?" and you had already closed the terminal ;)
I wrapped it in a script now, with more features, but this is the heart of it.
Never leave home without it.
Where $1 = author and $2 = mod name
You need to be running a daily build of Minetest (for example from the 'minetestdevs/daily-builds' PPA), or some bleeding edge mods will not work or crash the game.
Update a mod by entering its subdirectory under ~/.minetest/mods and doing
git pull && git submodule update --recursive --remote --init
If AppArmor is installed with all profiles enforced, Chromium may refuse to start, printing a "failed to launch zygote process" error on stderr.
This command switches the Chromium profile from enforce to complain mode, effectively un-sandboxing the browser, but depending on the system setup it may be a smaller deal than a nonfunctional application.
Checks if the aspect ratio is approximately 1.6 (16:10) or ~1.77777778 (16:9).
Requires mpv_identify from mpv project https://github.com/mpv-player/mpv/blob/master/TOOLS/mpv_identify.sh (this replaces mplayer -identify, or midentify)
This has been my "sysupgrade" alias since ca. 2006, first used on Debian Sid, then Sabayon, and it still does its duty on Mint nowadays without breaking stuff.
This can help with serious GUI lockups in KDE. It will only restart Plasma + widgets, not your session, so all your programs will stay running.
List images between 800 and 16384 pixels wide that can be displayed sized and trimmed on a widescreen display.
Requires the "wallpaper" utility.
Returns the global weighted BTC rate in EUR. Requires the "jq" JSON parser.
If you cat the file, all the parts of the command line are bunched up. If you use tr to convert the nulls to spaces, you're still left without a newline unless you add another step. This command does everything for you.
The ebay URL is the search query copied from the browser (here searching for bed stuff). The regex is for crap that should not be shown. Important is "Pickup only", which filters away all the things that cannot be shipped (a filter that cannot be done on Ebay's webpage).
It will output the title and url for all matching items, for all pages of the search result.
It also works for the German Ebay.
