Shell Programming and Scripting

Some old Unix shells have a bug with $@.
I have seen this work-around:

Code:

#!/bin/sh
echo "$0 `date`: ${1+$@}" >> /tmp/ld_log
ld_orig "${1+$@}"

If unknown at all, substitute the $@ stuff with $*

Code:

ld_orig $*

$* must be unquoted so has a problem with embedded space characters.

To answer Corona's query, I suppose the Cobol-85 compiler is able to distinguish between a shell script and a compiled code. When run separately, the shell script works just fine, but the Cobol-85 compiler rejects it with a "Cannot execute" error. It just struck me to try the same thing with a compiled code - so I wrote a little C program to just display the command line parameters and then pass on the same to the renamed ld command through the system() function.
