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?

grep -n SEARCHTERM file1 file2 ... Line numbers are printed with grep -n:
grep -n pattern file.txt To get only the line number (without the matching line), one may use cut:
grep -n pattern file.txt | cut -d : -f 1 Lines not containing a pattern are printed with grep -v:
grep -v pattern file.txt If you want only the line number do this:
grep -n Pattern file.ext | gawk '{print $1}' FS=":" Example:
$ grep -n 9780545460262 EXT20130410.txt | gawk '{print $1}' FS=":" 48793 52285 54023 grep -A20 -B20 pattern file.txt Search pattern and show 20 lines after and before pattern
4grep -nr "search string" directory
This gives you the line with the line number.
In order to display the results with the line numbers, you might try this
grep -nr "word to search for" /path/to/file/file The result should be something like this:
linenumber: other data "word to search for" other data When working with vim you can place
function grepn() { grep -n $@ /dev/null | awk -F $':' '{t = $1; $1 = $2; $2 = t; print; }' OFS=$':' | sed 's/^/vim +/' | sed '/:/s// /' | sed '/:/s// : /' } in your .bashrc and then
grepn SEARCHTERM file1 file2 ...
results in
vim +123 file1 : xxxxxxSEARCHTERMxxxxxxxxxx vim +234 file2 : xxxxxxSEARCHTERMxxxxxxxxxx Now, you can open vim on the correspondending line (for example line 123) by simply copying vim +123 file1 to your shell.
