Shell Tricks Part 1 – Substituting basename, dirname and ls commands

Substituting basename, dirname and ls commands

In Bourne shell, it is possible to use the following variable expansions as substitutes for the basename, dirname and ls commands

$ MYVAR=/path/to/basename
$ echo ${MYVAR##*/}
basename
$ MYVAR=/path/to/dirname
$ echo ${MYVAR%/*}
/path/to
$ echo *
bin boot dev etc home lib lost+found mnt opt proc root sbin tmp usr var
$

Hows That?
