🤼‍♂️ How to

Usage: semaphore COMMAND

Semaphore provides functionality to execute terminal commands in parallel.

Commands:

create	is a command to init a semaphore context
  -debug
    	show error stack trace
  -filename string
    	an absolute path to semaphore context (default "/tmp/semaphore.json")


add	is a command to add a job into a semaphore context
  -debug
    	show error stack trace
  -edit
    	switch to edit mode to read arguments from input (not implemented yet)
  -filename string
    	an absolute path to semaphore context (default "/tmp/semaphore.json")


wait	is a command to execute a semaphore task
  -debug
    	show error stack trace
  -filename string
    	an absolute path to semaphore context (default "/tmp/semaphore.json")
  -notify
    	show notification at the end (not implemented yet)
  -speed int
    	a velocity of report output (characters per second)
  -timeout duration
    	timeout for task execution (default 1m0s)

Complex example

$ semaphore create 2
$ semaphore add -- bash -c "cd /tmp; \
    git clone git@github.com:kamilsk/semaphore.git \
    && cd semaphore \
    && echo 'semaphore at revision' \$(git rev-parse HEAD) \
    && rm -rf /tmp/semaphore"
$ semaphore add -- bash -c "cd /tmp; \
    git clone git@github.com:kamilsk/retry.git \
    && cd retry \
    && echo 'retry at revision' \$(git rev-parse HEAD) \
    && rm -rf /tmp/retry"
$ semaphore wait
