grep -n help

2013-01-31  Source: Original Site  Category:Unix Shell Scripts  Views:1 


I am trying to create a script that greps a file for a character then returns the line number of that character. This is fine but when you use grep -n it returns the line number and the whole line of text. Is there away of getting it to just come back with the line number ?


cat filename | grep -n "="

this returns

16:============================================================================= ======================================================= 19:============================================================================= ======================================================= 22:============================================================================= ======================================================= 25:============================================================================= ======================================================= 28:============================================================================= ======================================================= 31:============================================================================= ======================================================= 35:============================================================================= ======================================================= 38:============================================================================= ======================================================= 41:============================================================================= ======================================================= 44:============================================================================= =======================================================

when all i need is the line number
