Say I have a symbolic link:

/path/to/foo->/path/to/some_file.txt

Say I have a shell variable x=/path/to/foo, how can I get some_file.txt in a shell variable y?

In zsh,

y=${x:A:t}

would expand to the tail of the absolute path of $x. So it would be some_file.txt unless some_file.txt is itself a symlink to something else.

Otherwise, you can use zsh zstat builtin:

zmodload zsh/zstat
zstat -A y +link -- $x && y=$y:t

You can use readlink to get the pathname of the target file and then basename to extract its filename:

y="$(basename -- "$(readlink -- "$x")")"
