rancid_par(1)						      General Commands Manual						     rancid_par(1)

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..]). 18 December 2007 rancid_par(1)
