Create an easy to pronounce shortened URL from CLI

Just add this function to your .zshrc / .bashrc, and by typing "shout *URL*" you get a randomly chosen English word that ShoutKey.com uses to short your URL. You may now go to shoutkey.com/*output_word* and get redirected. The URL will be valid for 5 minutes. (I've never used sed before, so I'll be quite glad if someone could straighten up the sed commands and combine them (perhaps also removing the whitespace). If so, I'll update it right away ;) ) Show Sample Output

Print all the lines between 10 and 20 of a file

Subtly different to the -n+p method... and probably wrong in so many ways....... But it's shorter. Just.

ThePirateBay.org torrent search

Make changes in .bashrc immediately available

Simply sourcing .bashrc does not function correctly when you edit it and change an alias for a function or the other way round with the *same name*. I therefor use this function. Prior to re-sourcing .bashrc it unsets all aliases and functions.

Takes and displays screenshot of Android phone over adb.

Dependencies on phone: adb access, screencap command, base64 command. Dependencies on computer: adb, sed, base64, display (from imagemagick, but can substitute other image viewer which reads from stdin). This should work around adb stupidies (i.e. that it replaces \n with \r\n) with base64.

Truncate long strings in columns and use custom header names

Using the --table-truncate ( -T ) option, you can specify the columns you will allow to be truncated. This helps when you have some columns that are unusually long, or a small terminal window. In this example we will print out the /etc/passwd file in columns. We are using a colon as our separator ( -s: ), defining that we want table output ( -t ), defining the column names ( -N ) and allowing the column NAME to be truncated ( -T ). Show Sample Output

column -s: -t -n . -N USERNAME,PASS,UID,GID,NAME,HOMEDIR,SHELL -T NAME /etc/passwd|sed "1,2 i $(printf %80s|tr ' ' '=')"

Add thousand separator with sed, in a file or within pipe

Does not necessarily require a file to process, it can be used in a pipe as well: cat filename | sed -e :a -e 's/$.*[0-9]$$[0-9]\{3\}$/\1,\2/;ta' I don't remember where I copy/pasted this from, I wish I credited the original author Show Sample Output

Add 10 random unrated songs to xmms2 playlist

If you're like me and want to keep all your music rated, and you use xmms2, you might like this command. I takes 10 random songs from your xmms2 library that don't have any rating, and adds them to your current playlist. You can then rate them in another xmms2 client that supports rating (I like kuechenstation). I'm pretty sure there's a better way to do the grep ... | sed ... part, probably with awk, but I don't know awk, so I'd welcome any suggestions. Show Sample Output

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. 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.

check open ports without netstat or lsof

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Quick plotting of a function

The arguments of "seq" indicate the starting value, step size, and the end value of the x-range. "awk" outputs (x, f(x)) pairs and pipes them to "graph", which is part of the "plotutils" package.

Restrict the use of dmesg for current user/session

Linux offers an interesting option to restrict the use of dmesg. It is available via /proc/sys/kernel/dmesg_restrict. You can check the status with: $ cat /proc/sys/kernel/dmesg_restrict Alternatively you can use sysctl: $ sudo sysctl -w kernel.dmesg_restrict=1 To make your change persistent across reboot, edit a fille in /etc/sysctl.d/.

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Backup with versioning

Apart from an exact copy of your recent contents, also keep all earlier versions of files and folders that were modified or deleted. Inspired by EVACopy http://evacopy.sourceforge.net

scp file from hostb to hostc while logged into hosta

While at the command line of of hosta, scp a file from remote hostb to remote hostc. This saves the step of logging into hostb and then issuing the scp command to hostc.

Get Lorum Ipsum random text from lorumipsum.com

This will generate 3 paragraphs with random text. Change the 3 to any number.

Grab the first 3 octets of your ip addresses

For machines that have many ip blocks spanning different Class C's, this will show which ones.
