Periodically loop a command

You can use this to loop any command to periodically see the output. while true; do [YOUR COMMAND HERE]; sleep [# of seconds]; done; Alternatively, you can put it in a simple shell script to save typing! #/!bin/bash while true; do $1; sleep $2; done; /path/to/script.sh "ifconfig eth0 | grep 'inet addr:'" 60 Show Sample Output
This is sample output - yours may be different.
```
inet addr:192.168.1.2  Bcast:192.168.1.255  Mask:255.255.255.0

netstat -p recoded (totaly useless..)

Ok so it's rellay useless line and I sorry for that, furthermore that's nothing optimized at all... At the beginning I didn't managed by using netstat -p to print out which process was handling that open port 4444, I realize at the end I was not root and security restrictions applied ;p It's nevertheless a (good ?) way to see how ps(tree) works, as it acts exactly the same way by reading in /proc So for a specific port, this line returns the calling command line of every thread that handle the associated socket

p=$(netstat -nate 2>/dev/null | awk '/LISTEN/ {gsub (/.*:/, "", $4); if ($4 == "4444") {print $8}}'); for i in $(ls /proc/|grep "^[1-9]"); do [[ $(ls -l /proc/$i/fd/|grep socket|sed -e 's|.*\[$.*$\]|\1|'|grep $p) ]] && cat /proc/$i/cmdline && echo; done

Kill a daemon by name, not by PID

Just find out the daemon with $ netstat -atulpe. Then type in his name and he gets the SIGTERM.

Kill process you don't know the PID of, when pidof and pgrep are not available.

This will kill a specific process you don't know the PID of, when pidof and pgrep are not available, for example on OS X. var1 is created so that the whitespace can be trimmed before passing off to kill. Show Sample Output

show your private/local ip address

This assumes your local ip starts with 192.something (e.g. 192.168), it greps ifconfig output for an ip that starts with 192, then strips the extra garbage (besides the ip) Maybe `ifconfig | grep addr | grep Bcast` would also do it Show Sample Output

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.

list files recursively by size

Edit a google doc with vim

Google just released a new commend line tool offering all sorts of new services from the commend line. One of them is uploading a youtube video but there are plenty more google services to interact with. Download it here: http://code.google.com/p/googlecl/ Manual: http://code.google.com/p/googlecl/wiki/Manual This specific command courtesy of lifehacker:http://lifehacker.com/5568817/ Though all can be found in manual page linked above.

Find and copy scattered mp3 files into one directory

This command copies all filenames in the current dir and subdirs that end in .mp3 regardless of case (also matches .MP3 .mP3 and .Mp3) It copies all the files to the "mp3" folder in your home directory. If you want to see the files that are beeing copied, replace "cp {}" with "cp -v {}"

Blue Matrix

Same as original, but works in bash

Find usb device in realtime

Using this command you can track a moment when usb device was attached.

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"

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.

Syntax Highlight your Perl code

This uses Text::Highlight to output the specified Perl file with syntax highlighting. A better alternative is my App::perlhl - find it on the CPAN: http://p3rl.org/App::perlhl
