In addition to what "rdcwayx" stated correctly... The ampersand usage allows the job to run in the background, freeing up the terminal command-line for additional work (you don't have to wait to enter another command). So using both nohup and ampersand at the end, will prevent the job from dying if you log off, but will allow opportunity to use that same terminal window for additional typing in of new commands while the submitted job is still executing.

Hi,
Using nohup it sends output automatically to $HOME/nohup.out - how do I direct this output to another named file instead, so I can run several scripts in the background at once, directing their outputs into individual log files?

globus-job-clean
GLOBUS-JOB-CLEAN(1) GRAM5 Commands GLOBUS-JOB-CLEAN(1)
NAME
globus-job-clean - Cancel and clean up a GRAM batch job
SYNOPSIS
globus-job-clean [-r RESOURCE | -resource RESOURCE]
[-f | -force] [-q | -quiet] JOBID
globus-job-clean [-help] [-usage] [-version] [-versions]
DESCRIPTION
The globus-job-clean program cancels the job named by JOBID if it is still running, and then removes any cached files on the GRAM service
node related to that job. In order to do the file clean up, it submits a job which removes the cache files. By default this cleanup job is
submitted to the default GRAM resource running on the same host as the job. This behavior can be controlled by specifying a resource
manager contact string as the parameter to the -r or -resource option.
By default, globus-job-clean prompts the user prior to canceling the job. This behavior can be overridden by specifying the -f or -force
command-line options.
OPTIONS
The full set of options to globus-job-clean are:
-help, -usage
Display a help message to standard error and exit.
-version
Display the software version of the globus-job-clean program to standard output.
-version
Display the software version of the globus-job-clean program including DiRT information to standard output.
-resource RESOURCE, -r RESOURCE
Submit the clean-up job to the resource named by RESOURCE instead of the default GRAM service on the same host as the job contact.
-force, -f
Do not prompt to confirm job cancel and clean-up.
-quiet, -q
Do not print diagnostics for succesful clean-up. Implies -f
ENVIRONMENT
If the following variables affect the execution of globus-job-clean.
X509_USER_PROXY
Path to proxy credential.
X509_CERT_DIR
Path to trusted certificate directory.
