Wait for Jobs

Waiting for jobs is especially useful for scripts. By default,

nc
                    run

returns immediately after you submit a job. This allows you to submit multiple jobs at once. There could be times when you want to run jobs in sequence, in which case option -w is very useful. With this option, nc run waits for the job(s) to finish ( Done or Failed ).

% nc run -w sleep 10
Resources= linux
Env      = D(VOV_ENV_SOURCE=vnc_logs/envdexin36362.env)
Command  = vw vwrap sleep 10
Logfile  = vnc_logs/20131231/111314.21781
JobId    = 04211346
vnc: message: Scheduled jobs: 1       Total estimated time: 0s

Wait for Jobs and Show Log File of the last job: -wl

With this option, nc run waits for the job(s) and shows the log file of the last job.

% nc run -wl date
Resources= linux
Env      = D(VOV_ENV_SOURCE=vnc_logs/envdexin36362.env)
Command  = vw vwrap date
Logfile  = vnc_logs/20131231/111530.21819
JobId    = 04211392
nc: message: Scheduled jobs: 1       Total estimated time: 0s
<<<STARTING ON rhino>>>
Tue Dec 31 11:15:31 PST 2002
<<<END OF LOG>>>
<<<EXIT STATUS 0>>>

Please only use -wl for jobs where you are actively monitoring the output. Such jobs listen to the vovservers event stream and are called 'notify clients'. They are more resource-intensive than plain batch jobs.

Wait for Jobs Using nc wait

You can also wait for jobs using the command nc wait. This is covered in "Job Control".
