Character Type Restrictions

Description Applies to Notes
Job name Jobs Special characters and spaces are okay to use in job names.
Job command Jobs Most special characters are okay to use in commands. Redirects (e.g. > and <), pipes (e.g. |), logical operators (e.g. && or ||) and semicolons need to be escaped unless they are meant to be used as shell operators.
Job substitutions Jobs @JOBID@, @NCJOBID@, and @IDINT@ in job names are substituted with the job's values for the job name, environment, and command.
Job array substitutions Jobs @INDEX@, @ARRAYJOBID@, @ARRAYID@, and @ARRAYIDINT@ in jobs that are in job arrays are substituted with the job's values
Set name Sets Special characters and spaces are okay to use in set names. Colons are used to denote hierarchy. Sets starting with "@@@" or "tmp:" are temporary sets and should not be used.
