Several of the shell-scripts contain non-POSIXisms (such as XPIisms and
BASHisms); this simple patch fixes them.
(Manual) substitutions done:
-a and -o => expressions that uses && and || instead
type => which
trap: use signal-names instead of signal-numbers
tail +<num> => tail -n+<num>
egrep => grep -E
If I've missed anything, feel free to complain. As soon as time
permits, I will finish my audit of the rest of the /bin/sh-scripts in
base, and submit patches for these as well.
Regards: David Weinehall
