There is the option -n, and many more in the manual page, worth reading.

thanks ... i was going thru man grep. –  user7044 Aug 26 '11 at 12:16

grep -n <pattern> <file> prefixes each line of output with the line number in the input file. Is this what you are looking for?

mid-air collision with enzotib, who was faster –  Petr Uzel Aug 26 '11 at 12:20

alias grep='grep -inE --color=auto'

This will color the match as well for easy reading.

Have you checked cat -n 'filename'. This will print the line numbers.
