Automatically run a command upon entering a certain directory?

  • 772

I'm using with and so I have say two different directories say:

~/Development/site1
~/Development/site2

So to set up my enviroment I normally go to ~/Development/site1 then run source bin/activate. Is it possible to have that command run automatically when I cd into one of these directories?

  1. Would a bash alias suffice? or does it have to be linked to entering the specific directory?

    My solution to bash alias.

    In ~/.bashrc check that .bash_aliases is ran.

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

    In ~/.bash_aliases

    alias siteone='cd ~/Development/site1 && source bin/activate'
alias sitetwo='cd ~/Development/site2 && source bin/activate'

    You could put this in your .bashrc to redefine the "cd" command: 

    cd()
{
    [ -z "$*" ] && builtin cd $HOME
    [ -n "$*" ] && builtin cd "$*"
    [ -f "./bin/activate" && source ./bin/activate
}
