On my system, no initscript has the line "provide dns" in it, so it might |
| 18 |
be possible that you don't have any file with that line. |

That said, you should use -r, and you don't need the -e switch: |
| 21 |
|
| 22 |
grep -r '^[[:space:]]\{1,\}provide[[:space:]]\{1,\}dns' /etc/init.d |
| 23 |
|
| 24 |
or, perhaps clearer |
| 25 |
|
| 26 |
grep -rE '^[[:space:]]+provide[[:space:]]+dns' /etc/init.d |
