Made the hostname variable UNIX-universal

[Mattio-cmd]

Not all unix and unix-like operating systems have hostname command installed by default. I used the standard uname with the -a flag and then i did some basic text processing with awk.

• uname -a | awk is unnecessary, just use uname -n

[Mattio-cmd]

• Not all system has awk.

Which systems does not have awk?
