Viewing Top Processes according to cpu, mem, swap size, etc.
I've wanted this for a long time, finally just sat down and came up with it. This shows you the sorted output of ps in a pretty format perfect for cron or startup scripts. You can sort by changing the k -vsz to k -pmem for example to sort by memory instead. If you want a function, here's one from my http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html $ aa_top_ps(){ local T N=${1:-10};T=${2:-vsz}; ps wwo pid,user,group,vsize:8,size:8,sz:6,rss:6,pmem:7,pcpu:7,time:7,wchan,sched=,stat,flags,comm,args k -${T} -A|sed -u "/^ *PID/d;${N}q"; }

When feeling down, this command helps
$ sudo apt-get install sl $ man sl

Remove Suspend option from XFCE logoff dialog

put an unpacked .deb package back together
If any changes have been made to the package while it was unpacked (ie, conffiles files in /etc modi‐fied), the new package will inherit the changes. This way you can make it easy to copy packages from one computer to another, or to recreate packages that are installed on your system, but no longer available elsewhere. Note: dpkg-repack will place the created package in the current directory.

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"

Close specify detached screen
-X Send the specified command to a running screen session. -S Option to specify the screen session if you have several screen sessions running. $screen -ls for listing current screens and its sessionname

External IP (raw data)
can be used in script like : echo $(wget -qO- http://utils.admin-linux.fr/ip.php)

List all authors of a particular git project
Gets the authors, sorts by number of commits (as a vague way of estimating how much of the project is their work, i.e. the higher in the list, the more they've done) and then outputs the results.

ssh autocomplete
Autocomplete from .ssh/config

grep for minus (-) sign
Use flag "--" to stop switch parsing
