Well yes, if you run it directly. The initial question was about variable assignment.

Your example in context:

$ cat cgiscript
ua=`echo "$HTTP_USER_AGENT" | sed "s#\;##g"` $ export HTTP_USER_AGENT=""whoami""""
$ sh -x ./cgiscript

++ echo whoami
++ sed 's#\;##g'
+ ua=whoami

All those quotes around ""whoami"""" cancel out, BTW. The shell sees: <export><SP><LAME><=><""><whoami><""><"">
