Of course, that'll work too.  :-)

I used an explicit subshell out of habit... became habitual for me back
when I was writing a lot of shell scripts on my system to control other
systems via telnet.  Had to do it that way because we weren't allowed to
"modify the platform" by "installing scripts on it", but they never said
anything about making scripts to automate the shell itself on my local
system... :-D
