26 ## Simple shell script that saves the Spooler alot of headaches.
27 ## This routine invokes a slow filter on each of the files in a
28 ## user's print request, sending the output to separate files.
29 ## The Spooler will take ANYTHING that goes to standard error
30 ## and give it to the user. Non-empty standard error or non-zero
31 ## exit code cause cancellation of the print request.
32 ##
33 ## Calling sequence:
34 ##
35 ## slow.filter prefix file1 file2 ... fileN
36 ##
37 ## "prefix" is prefix of full path name for output files. All we
38 ## do is append a ``-k'' for k = 1, 2, ..., N.

43 # Most of the time we don't want the standard error to be captured
44 # by the Spooler, mainly to avoid "Terminated" messages that the
45 # shell puts out when we get a SIGTERM. We'll save the standard
46 # error channel under another number, so we can use it when it
47 # should be captured.
