q(1) is a dead simple message queue written in bash. You can queue
messages or lock into a fifo. Messgaes are pushed and shifted. Messages
may be persisted in a log file that may be cleared when unlocked.
Push a message:
$ echo beep | q push
$ echo boop | q pushShift a message off q
$ q shift
beep
$ q shift
boop
You can lock the q so a message must be acknowledged before another can be pushed on to it.
$ q lock
$ echo boop | q push# in another terminal
$ q shift
boop
$ q unlockThe q can be streamed as well
$ unlock
$ q push a
$ q push b
