Flags

-d# 

Specify a character for # to be used as the token delimiter. This character is specified just as it is for the cut command. The default is a tab character.

-n

-l 

List the line number within the file as a token.

-c 

List the number of tokens on the line as a token. This count does not include the additional tokens that may be added by the -n, -l or -c flags.
