This isn't the cause of your problem (which has probably been solved by some |
| 15 |
of the other posts), but don't forget that grep matches regexps, not strings, |
| 16 |
and "." in a regexp matches any single character. Therefore your code will match |
| 17 |
"212a56b68c108" (for example), as well as the ip you probably intended to match. |
| 18 |
|
| 19 |
To make sure you only match the ip, you'll need to escape the .s and surround |
| 20 |
the regexp by quotes: |
| 21 |
|
| 22 |
grep '212\.56\.68\.108' |
| 23 |
|
| 24 |
I'm probably telling you things you already know ;-) And it probably won't |
| 25 |
matter much anyway, but I thought I'd mention it in case it helps someone. |
