A lightweight job multiplexer written in Go.
jobmux reads jobs from stdin, one job each line. It executes the jobs
concurrently, while keeping stdout and stderr of the jobs sorted.
If you are new to Go, you need to setup your Go environment. Please follow the instructions in http://golang.org/doc/install.
After setting up Go and and its environment, installation of jobmux is pretty simple:
cd $GOROOT
go get github.com/kaicheng/jobmux
Please make sure you have internet connection during installation process.
If we have a file(input) with indenpendent jobs:
job1 arg1 arg2
job2 arga argb argc
job3 argi argii argiii
The command
jobmux <input >stdout 2>stderr
will be equivalent to
$(SHELL) <input >stdout 2>stderr
jobmux only keep stdout and stdin sorted. If the jobs interference in environment variables, files, etc, the behavior is undefined.
jobmux caches all the outputs if previous jobs doesn't finish. The worst case is the first job finishes after all the other jobs, and jobmux caches all the outputs. Be prepared for that!
Check jobmux -h for arguments.
