override "cd" command. Now: - Check virtualenv for activate/deactivate. - Check git and show a status. - Show directory files (with "ls").

gistfile1.sh

# cd + virtualenv activation + ls + git status
function cd() {
    # default cd
    builtin cd $1;

    # virtualenv activation
    GIT_DIR=`git rev-parse --git-dir 2> /dev/null`
    if [[ $? == 0 ]]
    then
        if [[ -f $GIT_DIR/../.env/bin/activate ]]
        then
            . $GIT_DIR/../.env/bin/activate
        fi
    else
        if [[ $VIRTUAL_ENV != "" ]]
        then
            deactivate
        fi
    fi

    # optional ls
    ls

    if [ -d .git ]; then
        git status
    fi;
}
