Top Forums UNIX for Advanced & Expert Users make a foreground running process to run background without hang up Post 302230580 by bakunin on Saturday 30th of August 2008 04:44:34 AM

When you have already started the job you can use "nohup <pid>" to unattach it from the terminal you are on (this is the reason why processes stop when you log off - they are attached to a terminal and this terminal ceases to exist when you log off) so they won't stop when you log off.

Therefore:

Code:
$ job                    # starts the job
$ <CTRL-Z>               # stops the job
$ bg                     # puts the job in background
$ nohup <PID>            # unattaches the backgrounded job from the terminal

I hope this helps.

condor_wait(1)						      General Commands Manual						    condor_wait(1)

Name
       condor_wait Wait - for jobs to finish

Synopsis
       condor_wait [-help -version]

       condor_wait[-debug] [-wait seconds] [-num number-of-jobs] log-file[job ID]

Description
       condor_waitwatches  a  user  log file (created with the logcommand within a submit description file) and returns when one or more jobs from
       the log have completed or aborted.

       Because condor_waitexpects to find at least one job submitted event in the log file, at least one job must have been successfully submitted
       with condor_submitbefore condor_waitis executed.

       condor_waitwill wait forever for jobs to finish, unless a shorter wait time is specified.

Options
       -help

	  Display usage information

       -version

	  Display version information

       -debug

	  Show extra debugging information.

       -wait seconds

	  Wait no more than the integer number of seconds. The default is unlimited time.

       -num number-of-jobs

	  Wait for the integer number-of-jobsjobs to end. The default is all jobs in the log file.

       log file

	  The name of the log file to watch for information about the job.

       job ID

	  A  specific job or set of jobs to watch. If the job IDis only the job ClassAd attribute  ClusterId , then condor_wait waits for all jobs
	  with the given  ClusterId . If the job IDis a pair of the job ClassAd attributes, given by  ClusterId . ProcId , then condor_wait  waits
	  for  the specific job with this job ID. If this option is not specified, all jobs that exist in the log file when condor_wait is invoked
	  will be watched.

General Remarks
       condor_waitis an inexpensive way to test or wait for the completion of a job or a whole cluster, if you are trying to get a process outside
       of Condor to synchronize with a job or set of jobs.

       It can also be used to wait for the completion of a limited subset of jobs, via the -numoption.

Examples
       condor_wait  logfile

       This command waits for all jobs that exist in  logfile to complete.

       condor_wait  logfile 40

       This command waits for all jobs that exist in  logfile with a job ClassAd attribute  ClusterId of 40 to complete.

       condor_wait  -num 2 logfile

       This command waits for any two jobs that exist in  logfile to complete.

       condor_wait  logfile 40.1

       This command waits for job 40.1 that exists in  logfile to complete.

       condor_wait  -wait 3600 logfile 40.1

       This waits for job 40.1 to complete by watching	logfile , but it will not wait more than one hour (3600 seconds).

Exit Status
       condor_waitexits  with  0  if and only if the specified job or jobs have completed or aborted. condor_waitreturns 1 if unrecoverable errors
       occur, such as a missing log file, if the job does not exist in the log file, or the user-specified waiting time has expired.
