Important
This is a fork from watch-run that uses spawn instead of exec internally for the following reasons:

- spawn does not have a buffer limit for stdout
- spawn does not loses colored output when terminal allows it
- add option to specify several patterns passing several times the -p, --pattern option all the options will be
aggregated into a single array to pass to Gaze.
- add option to react only on certain events: added, changed, deleted or renamed.
- add verbose info, use -q, --quiet to reduce the noise. (the info about when the command is run and when it finish will always be printed regardless the value of --quiet)
- add option to skip executing the command if the command is already running -k, --skip-if-running.

Everything else is the same as the origina watch-run

watch-spawn(1)

> Re-execute a given command everytime something changes in a specific directory. Build upon gaze.

listen to changes on js/modules/*/.js and execute browserify

watch-spawn -p 'js/modules/*/.js' browserify main.js -o public/build.js

listen only to added, deleted events and execute browserify

watch-spawn -f 'added, deleted' -p 'js/modules/*/.js' browserify main.js -o public/build.js

all of previous but execute the command first and then wait to see if execute in again on any change

watch-spawn -f 'added, deleted' -p 'js/modules/*/.js' -i browserify main.js -o public/build.js

all of previous but wait 4 seconds before executing the command (except the first time)

watch-spawn -f 'added, deleted' -p 'js/modules/*/.js' -i -d 4000 browserify main.js -o public/build.js

all of previous and quiet

watch-spawn -q -f 'added, deleted' -p 'js/modules/*/.js' -i -d 4000 browserify main.js -o public/build.js

all of previous and skip if the command is already running

watch-spawn -k -q -f 'added, deleted' -p 'js/modules/*/.js' -i -d 4000 browserify main.js -o public/build.js
