Hi,all

I've a puzzle about a bash script in buildservice/src/build/build,

-------------------------------------------------------------------------- exec 1> >(exec -a 'build logging tee' tee -a $LOGFILE) 2>&1 ==========================================================================

I known this redirect stdout and stderr to $LOGFILE and stdout, and rename the cmdling look like this :" build logging tee -a $LOGFILE".

but what's mean about "1>" and a blackspace, and what's mean about ">(...)" ， I known "(...)" to exec a progress use fork, but when "(...)" done, a fd get ?

Look for "Process Substitution" in the bash manual page. Michal -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-buildservice+help@opensuse.org
