Can you quote your current sh script back so we can see how it looks at
your end?

If BIOSYM had space in it it could be broken into separate words. You
want to quote it to prevent the shell doing whitespace interpretation
of its value:
if [ "${BIOSYM:=undefined}" == undefined ]
or you could just say
if [ -z "$BIOSYM" ]
which means the same thing in this instance.

$status is the csh variable for the exit status of the previous command;
zero means success. Csh's if is rather arithmetic in outlook.
The equivalent shell would be:
lic_pack=`egrep "^MSI_LIC_PACK_DIR" <$rel_data`
if [ $? = 0 ]; then
I've taken the liberty of rewriting "cat $rel_data | egrep "^MSI_LIC_PACK_DIR""
to be shorter and more efficient, too.
