I find `screen` even more annoying than `script` for scripting purposes,
wonderful though it is for interactive use.
I really just want the redirection, not the many extra features that
`screen` adds.

Cf. above annoyance. For doing something with Vim under Apache (using
:TOhtml), I recently resorted to this hackery:
screen -q -d -m -S $sessionname vim -u NONE -N +'so $scriptname'
(Then, loop, waiting for one of:
1: the Vim script to touch a marker file that indicated completion
2: a specified timeout, in case something errored out, preventing a
clean Vim exit
)
screen -X -S $sessionname quit
Despite my annoyance (I'm easily annoyed), I tried your above
suggestion. It didn't capture stderr, so I added a flag that logging
was in progress and added a redirect for it (also added '-q' to the
`screen` commands):
(( $+logfile && ! $+doinglogging )) \
&& exec env doinglogging=true screen -L -c =(echo "logfile $logfile") -q -m -S script-$0 $0 $@
(( $+doinglogging )) && exec 2>&1
Seems okay for what I'm doing.
Thanks,
Ben
