How can I apply a NOT to a regular expression? I know how to do it with a single
character:
[a-y].jpg = a.jpg b.jpg ... y.jpg
[^a-y].jpg = z.jpg
What about the reverse of a whole expression?
not '(sally|sue)'
not 't[i-z]e'
Also, programs like grep seem to have much stronger regex support than does bash (ie
ls)
ls '(sally|sue)' doesn't work, but
grep string '(sally|sue)' does
Yet with ls, something like: {sally,sue} works.
What about something like ^{sally,sue} (not)?
What's the deal?
