Assuming your /bin/sh is actually the Bourne-again shell, this excerpt
from the Bash manual explains what's happening ("source" is a synonym
for "."):
"""
. filename [arguments]
Read and execute commands from the filename argument in the current
shell context. [...] If any arguments are supplied, they become the
positional parameters when filename is executed. Otherwise the
positional parameters are unchanged.
"""
So "source [script] [args]" clobbers the parameters of the *current*
shell context. So any of these should work:
* use "source init.sh" to use the same shell context;
* use "./init.sh $1" to use a new context; or
* save the needed parameters in other variables before clobbering them.
