Oh, sorry, I missed that.
Yes. You have your choice of sending to a file (concatenate)
or simply putting them into a directory.
The simplest way to have them sent to a file is:
lp:lp=/path_to_file
:sd=/...
Now if you simply want them LEFT in the directory and handled
in some other way, you use:
lp:lp=/dev/null
:sd=/...
:of=/path_to_handler
:filter=/path_to_junker
#/bin/junker
exit 0
The 'junker' is there just to make lprng happy.
The 'handler' program is a filter that gets all of the job
information including all of the data file names, control file
image, etc., and simply carries out its work.
Note that it must read from STDIN and look for the '\031\001' sequence
and then suspend itself to be compatible with the OF filter requirements.
You can do this by the following trivial loop:
static char stop[] = "\031\001"; /* sent to cause filter to suspend */
state = 0;
while( (n = read(0,inbuf,1)) > 0 ){
if( inbuf[0] == stop[state] ){
++state;
if( stop[state] == 0 ){
kill( getpid(), SIGSTOP);
}
state = 0;
continue;
} else if( state ){
state = 0;
if( write(1,stop,1) != 1 ){
Errorcode = JABORT;
LOGERR_DIE("Process_OF_mode: write failed");
}
}
if( write(1,inbuf,1) != 1 ){
Errorcode = JABORT;
LOGERR_DIE("Process_OF_mode: write failed");
}
}
if( state && write(1,stop,1) != 1 ){
Errorcode = JABORT;
LOGERR_DIE("Process_OF_mode: write failed");
}
You can also use PERL with the same logic.
