How to get only end base file name in a directory structure using shell script(bash) or Linux command

Question

I have directory structure like this

• MainDIR/DIr2/b.txt

• MainDIR/DIr1/a.txt

I want to get only base file names, like a.txt and b.txt

Answer 1

To get the basename of a file path, which is stored in a shell variable MYFILE , you can do it like this:

In Zsh it is easiest, because you don't need to create a separate process:

$MYFILE:t

in bash (and, I think, ksh), the only method I know is

$(basename $MYFILE)

This works in Zsh too, but has the drawback that a sub-process is needed.
