Occasionally I need to update my .bashrc file and every time I google for information on how to do different things. These are some more common things I end up putting into my .bashrc that I’ve found while googling.

#Common alias
alias ...='cd .. ; cd ..'
alias ..='cd ..'
alias _='cd -'
alias cls='clear'
alias fh='history | grep $1' #Requires one input
alias grep='grep --color'
alias h='history'
alias home='cd ~'
alias la='ls -allh'
alias ll='ls -allh'
alias ls='ls --color'

# the bash history should save 3000 commands
export HISTFILESIZE=3000

#Aliases for handling tarballs
alias zls='tar -tzf $1' #ls a tarball
alias ztr='tar -czvf $1 $2' #create a tarball
alias zun='tar -xzvf $1' #extract a tarball
