Awk multiple deliminators
I'm going through a list of files
Code:
CLINK_0.fits
CLINK_1.fits 
... 
CLINK_11.fits

and I want to grab the number. Since the number goes from single to double digits, I can't use fix widths. Currently, I'm using an ugly work around of
Code:
echo $x | awk -F_ '{print $2}' | awk -F. '{print $1}'

but I can imagine in the future I may want more versatility.

Is there any easy way to deliminate by both "_" and "." to create fields? Thanks.

Use 2 field separators:
Code:
awk -F"[_.]" '{print $2}'
