Directory naming convention

[Danny Crisp]

i have several directories that have the following naming convention: -

dir1234
dir5678

How would I display just the numbers for dir1234 for example and exclude dir?

Danny,

a="dir1234"
echo $a | cut -c4-

Hi:

There are several ways. One is to use the shell's built-in parameter substitution.

# X=dir123; echo ${X##dir}

See the manpages for 'sh-posix(1)' for details.

Regards!
