       rancid_par - parallel command processing


       rancid_par [-FHdefiqx] [-c  command] [-l  logfile] [-n #] [-p #] [file [file...]]


       rancid_par  takes a list of files to run a command on.  The first line of each file begins
       with a colon (:) or a pound-sign (#).  If a colon, the remainder of the line is a  command
       to  run for each of the subsequent lines.  If a pound-sign, then each subsequent line is a
       (self-contained) command, unless the -c option was specified,  in  which  case  the  lines
       become the arguments replacing the braces ({}s) in the -c argument.

       The input file may also be specified on stdin, in the format as previously described.

       In  each  of  the cases where the lines of the file, following the first, are not commands
       (ie: colon or -c), instances of open-close braces ({}) in the command will be replaced  by
       these values.

       For example, an inputfile whose contents is:

            : echo {}

       run with rancid_par like so:

            %rancid_par -q inputfile

       will produce the following output (order will vary):


       The command-line options are as follows:

       -F     Omit the footer that normally follows the output of each job.

       -H     Omit the header that normally precedes the output of each job.

       -c     Command  to  be  run  on  each of the arguments following the command-line options,
              where the first line of the input file(s) begins with a pound-sign (#).

       -d     Print debugging information on standard error (stderr).  Repeat the  option  up  to
              three times for more verbosity.

       -e     Split  args  by spaces, rather than using sh -c.  Note: -e is incompatible with the
              -i option.

       -f     No input file or STDIN, just run a quantity of the command specified with -c.

       -i     Run commands interactively through (multiple) xterm(1) processes.

       -l     Prefix of logfile name, as in prefix.N where N is  the  rancid_par  process  number

              Default: par.log.<time>.[0..]

       -n     Number of simultaneous processes.

              Default: 3

       -p N   Pause N seconds between running commands.

       -q     Quiet  mode.  Omit the typical processing logs and do not create the log files from
              -l, instead the children inherit stdout and stderr from rancid_par.  -q is mutually
              exclusive  with  the  -x  and  -l  options  and the option appearing last will take

       -x     View rancid_par logs in real-time via an xterm(1).


       par.log.T.N Log file; where T is the current time in seconds since the
       epoch and N is the rancid_par process number ([0..]).


       rancid_par was ported from the perl version.  It differs in the following manner:

       A)     If rancid_par receives a HUP/INT/TERM/QUIT signal, it does not print  the  commands
              that will not be run.

       B)     If  rancid_par  received  a  HUP/INT/TERM/QUIT signal, it does not exit immediately
              after sending kill to running jobs.  it waits for them to exit  so  that  they  are
              cleaned-up properly.  If a second signal is received, it dies immediately.
