If you want that variable to be effective with the egrep command you
must write it this way:

$ echo "Abby" | LC_ALL=POSIX egrep '^[A-Z]+$'

But neither of these commands actually print anything in my Debian 5.0
system. Something is configured differently in our systems.

Then there's something wrong with your system.
Which is not surprising considering how ignorant of Linux you are.

The fix for that is pathetically obvious.

Not a word of thanks for the effort.

I'll bet I've killfiled a score of your aliases already.

I have most common first names killfiled. Missed "harry".
Thanks. This way I eliminate every stinking troll using
the name.

Never mind, I'll figure out.

I already said "many thanks *in advance*" once in the original post. I
thought, I would do so once again toward the end of the discussion...
once the issue is (hopefully) fully resolved... with possibly multiple
answers... all tried out and fully grokked.

You need to add that setting to the right command (egrep in this case).

$ echo "Abby" | LC_ALL=POSIX egrep '^[A-Z]+$'
$ echo "ABBY" | LC_ALL=POSIX egrep '^[A-Z]+$'
ABBY

The advantage of using character classes is that it will work not just
with the ASCII subset, but with any uppercase character.

$ echo "CAFÉ" | LC_ALL=POSIX egrep '^[A-Z]+$'
$ echo "CAFÉ" | egrep '^[[:upper:]]+$'
CAFÉ

Hey thanks, Huibert, appreciate it!
