So, I have some nice tips for your .bashrc, with screenshots. Also a handy command to show your biggest packages in pacman/arch.

Simple Calendar with today marked as

alias tcal='cal | sed "s/^/ /;s/$/ /;s/ $(date +%e) / $(date +%e | sed '''s/./#/g''') /"' 

Fast cd up:

alias ..='cd ..'
alias ...='cd ../..' 

Network Info (LAN IP, IP and MAC):

netinfo ()
{
echo "Internal IPv4 address of eth0: "; ifconfig | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}'
echo "External IPv4 address: "; wget -q -O - checkip.dyndns.org|sed -e 's/.*Current IP Address: //' -e 's/

Biggest folders in directory Gigabyte version:

alias dug='du -h | grep ^[0-9.]*G | sort -rn | head -n 20'

Biggest folders in directory Megabyte version:

alias dum='du -h | grep ^[0-9.]*M | sort -rn | head -n 20'

Process Grep:

alias pg='ps -ef | grep '

Nice greeting when opening a bash shell:

PS1="u@h  -  tn${PWD}/ -$ "
echo "Welkom Remy,"
echo "Het is vandaag:";
date
echo "Deze PC draait op een:" 
/bin/uname -p
echo ""
netinfo;

(put this one at the end of your .bashrc file)

And the huge packages finder:

#!/bin/bash
pacman -Qi | awk '/Name/ { name=$3 } /Size/ { printf "%.3fMBt%sn", $4/1024, name }' | sort -rh | head -n $1
exit 0

(I've put this in /usr/bin/dup and chmodded it to 755).

Thanks to the arch forum for most of these tips!
