Hi Ralph, thanks for the explanation. So indeed, it seems that is what is
being used by startSeaside30_adaptor which does:


cat << EOF | nohup $GEMSTONE/bin/topaz -l -e $4 2>&1 >>
$GEMSTONE_LOGDIR/${1}_server-${2}.log &

OK, that worked and gets what I want. But....I am unable to apply the same
"Here Document" approach to my real needs:

cat ../scripts/login.st \$1 | su -m $GEMSTONE_USER -c \"$GEMSTONE/bin/topaz
-ql -T200000 \"

Notice that $1 is the topaz script I send as an argument (yes, it can have
a EOF at the end). Also, I am executing topaz with a "su -m -c ..." so that
changes the things I guess.

Do you know how can I adapt the above line to use the Here Document
features? I would like to access the arguments inside the topaz script sent
as argument ($1 in this case).

yes, thanks :)

mmm good idea.

So...to conclude:

/opt/gemstone/product/bin/topaz -ql -T200000 <<EOF
login
printIt
'$1' printString
%
exit
EOF

that works. But if I do exactly the same but in the file passed as
argument, it does not work anymore:

/opt/gemstone/product/bin/topaz -ql -T200000 <<EOF
input $1
EOF


Any ideas?

Thank!





Hope that helps.
