For each job there is one line of output, e.g. + + [2] 0:14 +Running copy file1 file2 & + +Here 2 is the job number of the job; 0:14 is the clock time in minutes and +seconds since the job was submitted; `Running' indicates that the task is +currently running while the `+' indicates that this was the last background +job started. The remainder of the line is a copy of the actual command +used to start the job. + +The possible states for a background job are: + +.nf + Done -- the job has finished normally + Exit N -- the job terminated with exit code N + Stopped -- the job is waiting for input from the user + (see the \fIservice\fR command) + Running -- the job is currently executing +.fi +.ih +EXAMPLES +.nf +cl> jobs + [1] 21:13 Done mkhelp >& dev$null & + [2] 0:05 +Running count *.hlp > _junk & +.fi +.ih +BUGS +Exit codes are rarely displayed when jobs terminate abnormally. +The CL checks for background job termination only when a command is +entered, hence the elapsed time shown will often be greater than it +should be. +.ih +SEE ALSO +kill, service +.endhelp |
