How about something like:
set "arg1" "arg2" "arg3"
some_program "$@"
Here's a fun little script that demonstrates this by dynamically
altering the arguments (decreasing them as it goes):
------------------------------------------------------------------------
#!/bin/sh
if [ "$#" -gt 0 ]
then
echo "$# args are: $@"
shift
if [ "$#" -ne 0 ]
then
set "$@"
fi
"$0" "$@"
fi
------------------------------------------------------------------------
Call it as:
./shellscript "arg 1" "arg 2" "arg 3" "arg 4" "arg 5"
This will run 5 times (only 5 arguments) and output five lines.
Of course if your original script uses the positional parameters you
will want to save them off first.
Cheers,
Andy
