go is often used to dispatch qef jobs, saving the output in a file and providing audit trails. It is also used by qremote (described in the next page) to detach qefs run on a remote host.

% go qef  # detach qef redirecting output to ,.g
% go -d qef  # output saved in $HOME/.qtree/goes/<host>/<pid>,g
% qremote -g qef  # uses go -d on remote host to run qef

go simply runs its argument commands redirecting the standard output and diagnostics as specified by flags. The default is to redirect both to the file ,.g. If there is already ,.*g files, they are renamed by inserting an `o' before the `g'. Another option d redirects the output to file in $HOME/.qtree/goes/host/pid,g. The command g can be used to view selected go files. goes is used to look at and cleanup the go audit trail to which go adds lines when a command begins and ends.

% go l

% go date

# no output as output redirected

% l
,.g       ,.og      appl      appl.o    incls._   qmkhist._
		srclist._

% cat ,.g

% g -o  # look at ,.og
,.g       appl      appl.o    incls._   qmkhist._ srclist._
# ,.og did not exist when l was run

% go -d qef  # put go file in ~/.qtree/goes tree

Note in the above the incomplete job (12939) on matt and the failed job (12919). One can use g to look at the diagnostics for job 12919.

% g -dL  # to get list of go -d files

1: /g/dt/.qtree/goes/matt/12919a,g

The above output illustrates yet another QEF advantage in that there is an automatic check to ensure that the clock on the executing host is within 10 seconds of the qdsrv host.

Other g options allows one to tail a go file, look at the go files with respect to qef header and trailer lines, and remove the selected go file.
