A menu based bash directory browser

This could be useful when you have long pathnames to browse around and these pathnames have similar names...so CDPATH may not work.

#!/bin/bash

function cd()
{
if [ -z "$1" ]
then
    pushd $HOME
    return 0
fi
THEDIR=$(echo $1|sed -e "s/\~/$(echo $HOME|sed -e 's/\//\\\//g')/g")
pushd $THEDIR >/dev/null 2>&1


}

function lsd()
{
if [ -z "$1" ]
then
    select mydir in $(dirs -v|awk '{print $2}'|sort -u)
        do
        cd $mydir
        break
        done
else
        if [ -d "$1" ]
        then
            select mydir in $(find $1 -type d)
                do
                    cd $mydir
                    break
        done
    fi

fi
