Why should i worry about the message being piped to /dev/null? |
| 87 |
|
| 88 |
I worry about a message saying "you have to do it by hand" although some |
| 89 |
harmful "magic" is going on behind the scenes (the egrep+grub command) |
| 90 |
although we are not informed about it (command is piped to /dev/null, |
| 91 |
not message about it, etc.). |
