// CommandContext is like Command but includes a context. // // The provided context is used to kill the process (by calling // os.Process.Kill) if the context becomes done before the command // completes on its own. func CommandContext(ctx context.Context, name string, arg ...string) *Cmd { if ctx == nil { panic("nil Context") } cmd := Command(name, arg...) cmd.ctx = ctx return cmd } shell命令很复杂，可以用sh文件。比如：
command.sh文件内容如下：
#!/bin/bash
nohup /home/nextstage/maya_002_wxrt/server/maya wxrt --wxrtCfgFile="/home/nextstage/maya_002_wxrt/server/conf/wxrt.toml" >/home/nextstage/maya_002_wxrt/maya.log &
echo $! >> /home/nextstage/maya_002_wxrt/maya.pid
//TODO 测试
c.Args = append(c.Args, "/home/nextstage/maya_002_wxrt/job/process/command.sh")
c.Name = "bash"
// c.Name = "E:\\mine\\圣诞树给你，放桌面上.exe"
cmd := exec.CommandContext(c.Ctx, c.Name, c.Args...)
