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"; }

Print out a man page
man -t manpagename gives a postscript version of said man page. You then pipe it to ls, and assuming you have cups set up, it prints in your default printer.

Rips CDs (Playstation, etc.) and names the files the same as the volume name

Beep siren
Infinitely plays beeps with sinusoidally changing sound frequency. Ideal for alarm on an event.

Print the IPv4 address of a given interface

Rename files in batch

Make .bashrc function to backup the data you changed last houres
The original overwrites any previous backups, and only saves exactly the last hours worth, but not 1 hour + 1 minute. This version creates or appends files, and backs up everything since the last backup (using the backups timestamp as the reference), plus it uses TMPDIR if set.

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"

Are the two lines anagrams?
This works by reading in two lines of input, turning each into a list of one-character matches that are sorted and compared.

Convert text to uppercase
Usage: upper [STRING]...
