bash - Grab the filename in Unix out of full path

Question

I am trying to get "abc.txt" out of /this/is/could/be/any/path/abc.txt using Unix command. Note that /this/is/could/be/any/path is dynamic.

Any idea?

Answer 1

In bash:

path=/this/is/could/be/any/path/abc.txt

If your path has spaces in it, wrap it in "

path="/this/is/could/be/any/path/a b c.txt"

Then to extract the path, use the basename function

file=$(basename "$path")

or

file=${path##*/}
