Get line number while using grep

grepline

I am using grep recursive to search files for a string, and all the matched files and the lines containing that string are print on the terminal. But is it possible to get the line numbers of those lines too??

ex: presently what I get is /var/www/file.php: $options = "this.target", but what I am trying to get is /var/www/file.php: 1142 $options = "this.target";, well where 1142 would be the line number containing that string.

Syntax I am using to grep recursively is sudo grep -r 'pattern' '/var/www/file.php'

One more question is, how do we get results for not equal to a pattern. Like all the files but not the ones having a certain string?

Best Solution

grep -n SEARCHTERM file1 file2 ...
