In the commands below I insert data to grep via standard input and
terminate with <Ctrl-D>. Lines that match the expression are echoed
back. To improve visibility I used -n option so we can see the line
number of the matched line. BUT.
Can anyone explain the following behavior?
Did anyone fiddle with the weight of letters?
Right
==========================================================
[harel_at_harellaptop tmp]$ grep -n '[ABCDEFGHIJKLMNOPQRSTUVWXYZ]'
123
abc
ABC
3:ABC
Wrong
====================================
[harel_at_harellaptop tmp]$ grep -n '[A-Z]'
123
ABC
2:ABC
abc
3:abc
--
Thanks.
