To ensure that it will never come back, you can edit /etc/modprobe.d/blacklist Add "blacklist pcspkr" sans quotes

Grep without having it show its own process in the results
The trick here is to use the brackets [ ] around any one of the characters of the grep string. This uses the fact that [?] is a character class of one letter and will be removed when parsed by the shell. This is useful when you want to parse the output of grep or use the return value in an if-statement without having its own process causing it to erroneously return TRUE.

Removes file with a dash in the beginning of the name

Rsync between two servers
copying files from one server to another using rysnc. Root access need to be allowed on the destination.
