NAME

       rancid_par - parallel command processing

SYNOPSIS

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

DESCRIPTION

       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 it operates as if the argument to -c had followed a colon  on  the
       first line.

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

       For example, a inputfile whose contents is:

            : echo {}
            a
            b
            c

       run with rancid_par like so:

            %rancid_par -q inputfile

       will produce the following output (order will vary):

            b
            a
            c

       The command-line options are as follows:

       -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).

       -f     No  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 ([0..]).

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

       -n     Number of simultaneous processes.

              Default: 3

       -q     Quiet mode.  Do not log anything.  -q is mutually exclusive with
              the  -x  and  -l options and the option appearing last will take
              precedence.

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

FILES

       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..]).
