get the last digit(s) from a line or file

[support_billa]

hello,

i tried several tests to get the last digit(s) from a line or file.

my prefered command is "sed"

but in "sed"   '*' doesn't   mean zero or more occurence like in "grep" , so i use "{0,\}"

example:

RETURN 1

RETURN 11

RETURN 1234

my tests :

echo "RETURN 1" | sed -n '$s/.* \([0-9]\{0,\}\)$/\1/p'
echo "RETURN 11" | sed -n '$s/.* \([0-9]\{0,\}\)$/\1/p'

"*" works fine for me.

$ echo "RETURN 1234" | sed -n '$s/.* \([0-9]*\)$/\1/p'
1234

Yes but it is very hard to get to your attachment.

And you might be able to delete your empty post if you hadn't replied to it.

Hi:

# echo 'RETURN 1234' | sed -e 's/[^0-9]*\([0-9]*\)$/\1/'
1234
# echo 'RETURN1234'  | sed -e 's/[^0-9]*\([0-9]*\)$/\1/'
1234

 Regards!

How about a kudo to go with that solution flag?

As Pete has pointed out, marking a solution does *not* creat a kudos.  That's another counter-intuitive new feature of this new-fangled community we share.
