This sets the -n flag, and then sets $1 to "/tmp/tmpscript".  If you
want to set the -n flag, and then source the script, do this:
bash -c 'set -n; . /tmp/tmpscript'

Thanks, but why am i still getting zero output?

address@hidden /root]# bash -c 'set -n; . /tmp/tmpscript'
address@hidden /root]# chmod u+x /tmp/tmpscript
address@hidden /root]# bash -n /tmp/tmpscript
address@hidden /root]#


Should i try a "real" syntax error?  like what?

thx,

george
