FN_DATE_TODAY
FN_DATE_LASTDAY

How can i achieve that
Thanks
Assuming that you're using a shell that performs the standard parameter expansions, the following script shows one way to do what you want:
Code:
for i in FN*
do      printf "%s cuts down to %s\n" "$i" "${i%_*}"
done

which (if the only two files in the current directory having filenames starting with FN are the two you listed), produces the output:
Code:
FN_DATE_LASTDAY_19990178654321.txt cuts down to FN_DATE_LASTDAY
FN_DATE_TODAY_20010178654321.txt cuts down to FN_DATE_TODAY
