Some shortcuts I need in basrc

bashrc

command_exists () {
    type "$1" &> /dev/null ;
}

# grep always with color and line number 
alias grep='grep -n --color=always'

# git
if command_exists git ; then
    alias gitco='git checkout'
    alias gist='git status'
    alias gipu='git pull'
    #git-fetch-all
    alias gitfetchall='for remote in `git branch -r`; do git branch --track $remote; done; git fetch --all;vgit pull --all'
fi

# apache
if command_exists apache2 ; then
    alias apacherelod='sudo service apache2 reload'
fi

# memcached
if command_exists memcached ; then
    alias memdrelod='sudo service memcached restart'
fi
# don't put duplicate lines in the history. See bash(1) for more options
export HISTCONTROL=ignoredups

# enable color support of ls and also add handy aliases, like grep
if [ "$TERM" != "dumb" ]; then
    eval "`dircolors -b`"
    alias ls='ls --color=auto'
fi

# memcached
if command_exists youtube-dl ; then
    alias youtube-dl='youtube-dl --extract-audio --audio-format mp3  --audio-quality  0 '
fi
