如何在特定文件夹中运行Shell命令 [英] How to run a shell command in a specific folder

问题描述

我可以使用此 out，err:= exec.Command("git"，"log").Output()获得命令的输出，该命令将在与命令相同的路径中运行可执行位置.

I can use this out, err := exec.Command("git", "log").Output() to get an output of the command which will run in the same path as the executable location.

如何指定要在哪个文件夹中运行命令?

How do I specify in which folder I want to run the command?

推荐答案

exec.Command() 返回类型为 * exec的值.Cmd . Cmd 是一个结构，并且具有 Dir 字段:

exec.Command() returns you a value of type *exec.Cmd. Cmd is a struct and has a Dir field:

// Dir specifies the working directory of the command.
// If Dir is the empty string, Run runs the command in the
// calling process's current directory.
Dir string

因此只需在调用 Cmd.Output()之前进行设置即可:

So simply set it before calling Cmd.Output():

cmd:= exec.Command("git", "log")
cmd.Dir = "your/intended/working/directory"
out, err := cmd.Output()

还请注意，这特定于 git 命令； git 允许您使用 -C 标志传递路径，因此您也可以这样操作:

Also note that this is specific to git command; git allows you to pass the path using the -C flag, so you may also do what you want like this:

out, err := exec.Command("git", "-C", "your/intended/working/directory", "log").
    Output()
