Runcmd

Should be a Go library to execute external commands.

Import the library:

import (
    "github.com/enr/runcmd"
)

You can use this library in two ways:

• Run
• Start

Run starts the specified command, waits for it to complete and returns a result complete of stdout and stderr:

executable := "/usr/bin/ls"
args := []string{"-al"}
command := &runcmd.Command{
    Exe:  executable,
    Args: args,
}
res := command.Run()
if res.Success() {
    fmt.Printf("standard output: %s", res.Stdout().String())
} else {
    fmt.Printf("error executing %s. Exit code %d", command, res.ExitStatus())
    fmt.Printf("error output: %s", res.Stderr().String())
    fmt.Printf("the error: %v", res.Error())
}

Start starts the specified command but does not wait for it to complete.

executable := "/usr/local/bin/start-server"
command := &runcmd.Command{
    Exe:  executable,
}
logFile := command.GetLogfile()
// maybe you want to follow logs...
t, _ := tail.TailFile(logFile, tail.Config{Follow: true})
command.Start()
runningProcess := command.Process
