How to cut the third value
Guys,

Please can some one help me how to cut the third value on this ? I don't want to use cut as this number can grow to 100000

UKPP1_1_1002_639156890.arc

And i need the command to return 1002

Thanks in advance.

Regards,
Ganesh

try this:
Code:
some_var=UKPP1_1_10045452_639156890.arc
echo $some_var | cut -d '_' -f 3

What's wrong with using cut for that? It's not like a string which is seven bytes long is going to be a major showstopper over a string which is four bytes long.

Code:
cut -d_ -f3
