You don’t have to call the external basename
command. Instead, you could use the following commands:
$ s=/the/path/foo.txt
$ echo "${s##*/}"
foo.txt
$ s=${s##*/}
$ echo "${s%.txt}"
foo
$ echo "${s%.*}"
foo
Note that this solution should work in all recent (post 2004) POSIX compliant shells, (e.g. bash
, dash
, ksh
, etc.).
