I think cabrao meant that you didn't need the *. Besides, with your grep in single quotes the shell would not expand it in any way so it would look for filenames literally including v00*

At the very least in a regular expression you would need .* (without single quotes)

A * in a regular expression matches 0 or more of the last expression (in your case the character 0), whereas . means match any character and .* matches 0 or more of any character.

You should also change your ls to "ls -1".

Code:
version=$(ls -1 $SOFTWARE/src/$progname | grep v00  | tail -1)

I don't know the names of the files in your $program directory, but:
Code:
version=$(ls -1 $SOFTWARE/src/$progname/*v00* | tail -1)

should also do the same thing.

Don't confuse the * in how the shell expands filenames with * in a regular expression - they're not the same thing.
