Command queue

About

This is coding exercise inspired by mkopta/q.

This tool queues commands to execute them one by one.

Install

go get github.com/hullerob/q/{q,qd}

Example

In one terminal:

QADDR="unix:/tmp/q.sock" qd

In other terminal:

export QADDR="unix:/tmp/q.sock"
q a cp -r some/dir /mnt/some/slow/disk
q a cp -r some/other/dir /mnt/some/slow/disk
q l

Q Commands

q h          print help about commands
q a [cmd]    add cmd to queue
q i          print status of queue (length of queue)
q l          print queued commands
q r          print info about all commands
q R          run queue
q S          stop queue

There are currently no other commands.

What is QADDR

Anything in format <network>:<addr> that is accepted by Go's net.Listen(network, addr) and rpc.Dial(network, addr).

Examples:

• unix:/tmp/socket

• tcp:127.0.0.1:9876

BUGS

No support for clean qd shutdown, does not clean socket file.
