- program variable
- (text) file

Try this if you want to use the underscore as separator:
Code:
foo=filename_a_ALL.cmd
echo "${foo##*_}"

Or, if it really needs to be the last 7 characters:
Code:
echo "${foo#"${foo%???????}"}"

What shell are you using (and what version of that shell)?

What operating system are you using?

Wouldn't "7 chars from left of filemane(sic)" when the filename is filename_a_ALL.cmd be filenam instead of ALL.cmd?
