Find the package that installed a command

Get your local IP regardless of your network interface
Shows only IP-addresses of ifconfig except 127.0.0.0/8. I fixed the script to work on more systems and configs short info /inet/!d; #grep inet /127.0/d; # grep -v 127.0 /dr:\s/d; # grep -v dr: s/^.*:\(.*\)B.*$/\1/ # remove everything exept between : and B

Replace space in filename
This commands removes space from all the files with specific extension. I've specifed *.jpg as an example.

List processes sorted by CPU usage

vi a new file with execution mode
$ vix /tmp/script.sh Open a file directly with execution permission. Put the function in your .bashrc You can also put this in your vimrc: $ command XX w | set ar | silent exe "!chmod +x %" | redraw! and open a new file like this: $ vi +XX /tmp/script.sh

find co-ordinates of a location
Just add this to your .bashrc file. Use quotes when query has multiple word length.

Trim png files in a folder
That should be a short as it can get.

Backup a remote database to your local filesystem
I have this on a daily cronjob to backup the commandlinefu.com database from NearlyFreeSpeech.net (awesome hosts by the way) to my local drive. Note that (on my Ubuntu system at least) you need to escape the % signs on the crontab.

back ssh from firewalled hosts
host B (you) redirects a modem port (62220) to his local ssh. host A is a remote machine (the ones that issues the ssh cmd). once connected port 5497 is in listening mode on host B. host B just do a ssh 127.0.0.1 -p 5497 -l user and reaches the remote host'ssh. This can be used also for vnc and so on.

Text graphing ping output filter
Nasty perl one-liner that provides a sparkline of ping times. If you want a different history than the last 30, just put that value in. It (ab)uses unicode to draw the bars, inspired by https://github.com/joemiller/spark-ping . It's not the most bug-free piece of code, but what it lacks in robustness it makes up for in capability. :) If anyone has any ideas on how to make it more compact or better, I'd love to hear them. I included a ping to google in the command just as an example (and burned up 10 chars doing it!). You should use it with: $ ping example.com | $SPARKLINE_PING_COMMAND
