如何在多行而不是单行输出上打印 linux 组名 [英] How to print linux group names on multiple line instead of single line output

问题描述

我尝试过 getent、组命令、id -Gn $user 和一些 sed 组合，但我认为我无法实现，因此联系了其他程序员.
我希望能够打印这个:groups abc123
输出abc123 : devops 构建测试设计

I have tried getent, group command, id -Gn $user and some sed combination but I don't think I am able to achieve hence reaching out to fellow programmers.
I want to be able to print this : groups abc123
Output abc123 : devops build test design

预期输出
组:
- 开发运维
- 构建
- 测试
- 设计

Expected Output
groups:
- devops
- build
- test
- design

推荐答案

据我所知，您正在尝试将用户的组转换为 yaml 数组，尝试使用:

From what I see, you are trying to convert the groups of your user to an yaml array, try to use:

echo "groups:" ; for i in $(id -Gn myuser);do echo "  - $i" ;done

groups:
  - users
  - lp
  - vboxusers
  - kvm

你也可以使用:

echo "groups: [ $(groups myuser | sed -e 's/.+s+:s+(.+)/1/g' -e 's/(s+)/, /g') ]"

groups: [ myuser, lp, vboxusers, kvm ]
