NAME
rancid_par - parallel command processingSYNOPSIS
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..]).
