Generate background office noise using Digg feeds and OSX.

Instead of having someone else read you the Digg headlines, Have OSX do it. Requires Curl+Sed+Say. This could probably be easily modified to use espeak for Linux.
This is sample output - yours may be different.

Get your external IP address

Here's a version that uses netcat (although I'd much rather use curl!).

Read multiple lines of a file based on regex matching a single line

Finds the line number matching the regex, then passes that to BC for some math, passes that to head, and uses tail to trim off the unwanted section at the top. The whole thing is spit out to a script that can then be shared or run. Comes in handy for reading select sections from error logs.
This is sample output - yours may be different.
-2

for i in `grep -n "SomeRegEx" foo.txt | sed 's/:/ /' | awk '{print $1}'`; do echo "head -n `echo "$i+4" | bc` foo.txt | tail -n 5"; done > headsandtails.sh

Resample MP3's to 44.1kHz

This heavy one liner gets all the files in the "/music/dir/" directory and filters for non 44.1 mp3 files. After doing this it passes the names to sox in-order to re-sample those files. The original files are left just in case.
This is sample output - yours may be different.
-2

file /music/dir/* | grep -v 44.1 | sed 's/:.*//g' | grep .mp3 | { while IFS= read; do filebak="\"$REPLY.original\""; file="\"$REPLY\""; mv $file $filebak; sox -t mp3 $filebak $file rate 44k; done; };

Display a random man page

Broaden your knowledge of the utilities available to you in no particular order whatsoever! Then use that knowledge to create more nifty one-liners that you can post here. =p Takes a random number modulo the number of files in $dir, prints the filename corresponding to that number, and passes it as an argument to man.

dir="/bin"; man $(ls $dir |sed -n "$(echo $(( $RANDOM % $(ls $dir |wc -l | awk "{ print $1; }" ) + 1 )) )p")

Display a random man page

Great idea camocrazed. Another twist would be to display a different man page based on the day of the year. The following will continuously cycle through all man pages: man $(ls /bin | sed -n $(($(date +%j) % $(ls /bin | wc -l)))p)

Rename files in a directory in an edited list fashion

Instead of tedious manual mv commands and tabbing, this routine creates a file listing all the filenames in the PWD twice, edit the second instance on each line to the new name, then save the file, the routine does the rest. Feel free to replace nano with your holy war editor of choice. You will get a lot of "mv: 'x' and 'x' are the same file" warnings, these could be cleaned up but the routine works.

ls > ls; paste ls ls > ren; nano ren; sed 's/^/mv /' ren|bash; rm ren ls

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.

Share Your Commands

Check These Out

Rename files in batch

Write comments to your history.

A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

Check syntax of remote ruby file

List all directories only.

Undocumented syntax, but should work on every shell. It'll list all directories in the current one. Change `*/` into globbing `**/` for recursivity.

Copy the full path of a file to the clipboard (requires xclip or similar)

Handy for those times you need to paste a file path in an IDE or some other app. sudo apt-get install xclip Then, for convenience, alias xclip to 'xclip -selection c' so you can just do something like realpath . | xclip

c_rehash replacement

When you don't have c_rehash handy. Really simple - if you have a .pem file that doesn't really contain a x509 cert (let's say, newreq.pem), it will create a link, simply called '.0', pointing to that file.

Alias for lazy tmux create/reattach

If a tmux session is already running attach it, otherwise create a new one. Useful if you often forget about running tmuxes (or just don't care)

Get shellcode of the binary using objdump

Anyone can make the command smaller & easier? :)

View and review the system process tree.

The "pstree" command uses special line-drawing characters. However, when piped into the "less" pager, these are normally disabled.

Disconnect telnet

You are stuck with testing a tcp port using telnet, and must kill the telnet session from another terminal... Or, press ctrl+5 and write close/quit to force the current connection to close..

Stay in the loop…

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.
