I want to be able to have a single line that outputs to stdout and a
logfile without spawning a subshell by using a pipe. I'd imagine this
kind of thing must be in build scripts? I want two modes, though:

1. output to stdout only
2. output to stdout and logfile

I +could+ just use tee, it's true but then I'd need two lines, AFAIK:

[ -n "$stdout_only" ] && echo hi
[ -z "$stdout_only" ] && echo hi | tee -a /tmp/mylog.txt

I had a quick go through the i/o section of the advanced bash scripting
guide but nothing leapt out at me.

cheers,

ben.
