I wan't to show all lines from file which consist of only 3 char:
grep ^.{3}$ file
Why this does't work?? Isn't it the same as :
grep ^...$ file ??

grep -E "^.{3}$" file
seems to work better (or egrep). Or use \{ and \}.

Hmm so you have used -E option, an ^.{3}$ works fine! which mean
extended grep what is the difference between extended and normal one?
