bash: extracting last two dirs for a pathname

Question

I seem to have failed at something pretty simple, in bash. I have a string variable that holds the full path to a directory. I\'d like to assign the last two di

Answer 1

function getDir() {
echo $1 | awk -F/ '
{
    n=NF-'$2'+1;
    if(n<1)exit;
    for (i=n;i<=NF;i++) {
        printf("/%s",$i);
    }
}'
}

dir="/a/b/c/d/e"
dir2=`getDir $dir 1`
echo $dir2

You can get any number of directories from the last from this function. For your case run it as,

dir2=`getDir $dir 2`;

Output : /d/e
