[arch-general] X fails to start after editing ~/.xinitrc

[Juan R. de Silva]

I have a new arch install with basic X environment added and successfully 
tested.

Following instructions here https://wiki.archlinux.org/index.php/Fonts 
I installed "terminus" fonts, created ~/.xinitrc file and added to it the 
following lines as advised:

xset +fp /usr/share/fonts/local
xset fp rehash

After this X fails to start with error:

"/usr/bin/startx: Line 127: hostname: command not found"

When ~/.xinitrc file deleted, X starts as before just fine.

Could somebody help me to figure out what am I doing wrong, please?
