My .bashrc

It's good to setup your system exactly as you want. bashrc file is great option if you like to apply your settings after logging in.
So this post shows my bashrc file...

# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.

if [ -f ~/.bash_aliases ]; then
        . ~/.bash_aliases
fi

# Disable annoying tty console beep
# ssh sets TERM to dumb when using scp or other...
if [ "$TERM" != "dumb" ]; then
        setterm -blength 0
        setterm -bfreq 0
