Hi

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 ?

example

Code:

cat filename | grep -n "="

this returns

Code:

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

when all i need is the line number

Try this:

Code:

grep -n "=" filename|cut -d':' -f1
