一简介

用于运行命令源码文件。

只能接受一个命令源码文件以及若干个库源码文件作为文件参数。

其内部执行步骤是：先编译源码文件再运行

二 goc2p项目介绍

1、项目地址

https://github.com/hyper0x/goc2p

2、项目说明

《go并发编程实战》的示例项目

3、项目安装

用git clone获取项目，并将其根目录作为一个工作区

4、ds命令和pds命令

三 go run命令实战

[[email protected] ds]# cd ~
[[email protected] ~]# ls |grep go
go1.8.3.linux-amd64.tar.gz
gobin
goc2p
golib
goproject
[[email protected] ~]# cd goc2p/src/helper/ds
[[email protected] ds]# ls
showds.go
[[email protected] ds]# go run showds.go
/root/goc2p/src/helper/ds:
showds.go
[[email protected] ds]# go run showds.go -p ~/goc2p/src/helper/
/root/goc2p/src/helper/:
ds/
showds.go
pds/
showpds.go

四 go run常用标记的使用

五常用标记案例演示

[[email protected] ds]# go run showds.go
/root/goc2p/src/helper/ds:
showds.go
[[email protected] ds]# go run -n showds.go
