bad v0.10.0

bad
is a command line tool that allows you to execute a command multiple times
concurrently for a given number of subjects.
It is general enough for just about anything that requires parallel execution, and it's bad enough to accomplish it with ease!
##Why the name? I couldn't think of anything better so I entered "batch command" at: http://www.portmanteaur.com/?words=batch+command+node
bad
stood out :)
##Usage
Usage: bad --exec curl --for "google.com linkedin.com" --argv "-s"
Options:
-h, --help output usage information
-V, --version output the version number
--debug print information for debugging
-s, --silent show as little as possible.
--exec <command> the command to run. This is passed directly to spawn.
--for <subjects> a comma separated list of subject sets.
Each subject set is a whitespace separated list of subjects.
Subjects are appended to argv except when --to-env is given.
--argv [args] a whitespace separated list of arguments to pass to the command.
--to-env <varnames> a comma separated list of varname sets.
Each varname set is a whitespace separated list of varnames.
Varnames are mapped to the corresponding subject.
--show-time display time stats.
##Example This would silently curl the given urls concurrently:
bad --exec curl --argv '-s' --for "google.com linkedin.com npmjs.org"
##Advanced mapping
You can map subjects to an environment variable using the --to-env
flag.
Consider this example:
bad --exec echo --for '1 2, 3 4 5, 6' --to-env 'FOO DOO, XOO, ZOO'
....
#FOO set to 1
#DOO set to 2
#XOO set to 3
#XOO set to 4
#XOO set to 5
#ZOO set to 6
