Is there a number class in regex? [SOLVED]

[musher0]

Hello all.

As the title says: "Is there a number class in regex?" A "class" or
whatever it may be called.

regex has a class for ::word:: but I couldn't find one for digits.
(Or maybe I need new glasses?!)

It's not a big problem, it's efficient as it is written, but I would like to
compact the list of numbers in the following line:

Code: Select all

cd PupMenu
ls -Algo --file-type ./* | awk '{ print $NF }' | grep -E -v "^0|^1|^2|^3|^4|^5|^6|^7|^8|^9|~|^_|oris\/|ites\/" > ../aewm-menu.lst

This:

Code: Select all

"^[0-9]|~|^_|oris\/|ites\/" > ../aewm-menu.lst

does NOT work. It creates an almost empty menu, it seems to skip all
entries that come afterwards.

The full script is attached as a zip. The goal is to recreate an aemenu
from the wmx menu.

Thanks in advance for any pointers.

~~~~~~~~~~
PS -- Please don't mind the silly variable names and file names. I was
tired when I wrote the script.

I was tired when I wrote the script.

Aren't we (almost) all somehow tired when we do write scripts?

Probably we would program in C or similar Programming Language if we wouldn't be that much tired?

Funny guy!

As to writing in C, the bash script is as respectable, you know.

BFN.

This:

Code: Select all

"^[0-9]|~|^_|oris\/|ites\/" > ../aewm-menu.lst

does NOT work.

It works for me.

If your grep version recognizes POSIX bracket expressions you could, instead of grep -E -v "^[0-9]", use grep -E -v "^[[:digit:]]", but that would be less compact...

Ah. Thank you very much, MochiMoppei. Very helpful.
