Angry Get last subfolder on a path...


So lets say I create a bash script and I assign a folder variable like:


#!/bin/bash
....
Myvariable_FOLDER_PATH=/PATH/TO/SPECIFIC/SUBFOLDER


is there any way to make another variable with just the specific SUBFOLDER

(?some command?)----> will make My_variable_subfolder = SUBFOLDER

so if I do
echo $Myvariable_FOLDER_PATH

i get: /PATH/TO/SPECIFIC/SUBFOLDER


and echo $My_variable_subfolder

i get: /SUBFOLDER


The tree and path names will change so I jjust want the last subfolder that I will access to access its files.
Thanks...

Just use parameter substitution:
Code:
Myvariable_FOLDER_PATH=/PATH/TO/SPECIFIC/SUBFOLDER
My_variable_subfolder=${Myvariable_FOLDER_PATH/*\//}
or
Code:
My_variable_subfolder=${Myvariable_FOLDER_PATH##*/}

basename

The basename command always gives you the last component of a fully qualified path. This can be a directory or a file.

e.g. "basename /var/named/chroot/var/named" returns "named".

Even though using the basename command probably makes the script more readable, using parameter substitution is probably faster since you don't start another process.
