Code:

cut -f2 file >newfile

awk '{print $2,NR}' "$file_name" | cut -d'[' -f2 | tr -d ']' > "$backfile"

Yeah, you could cut on [ if you want to remove the brackets. The awk is rather unnecessary, though.

Code:

cut -d'[' -f2 file | cut -d']' -f1 >newfile

Or just with awk:

Code:

awk 'BEGIN{FS="\[|\]"}{print $2}' file
