So you're storing a file on a public server that is beyond your control and you make your shell read it every time you launch it ?

What could possibly go wrong ?! ;-)

head just prints the contents of the file, it doesn't execute anything.

and neither does my terminal emulator...

Pipe it through something that strips control characters before printing perhaps?
