How to find Linux Distribution name using shell script?
提问by Pratik Patil
I am writing a shell script in which I need the current operating system name to make it generic. Like:
我正在编写一个 shell 脚本，在该脚本中我需要当前的操作系统名称以使其通用。喜欢：
if [ $Operating_System == "CentOS" ]
then
echo "CentOS";
# Do this
elif [ $Operating_System == "Ubuntu" ]
then
echo "Ubuntu";
# Do that
else
echo "Unsupported Operating System";
fi
How will it be possible? Applying regular expression on lsb_release -acommand or something else?
怎么可能？在lsb_release -a命令或其他东西上应用正则表达式？
Thanks..
谢谢..

You can get the info from lsb_release:
您可以从lsb_release以下位置获取信息：
echo "$(lsb_release -is)"
istands for distributor id.
i代表经销商 ID。
sstands for short.
s代表简称。
For ex. It shows Ubuntuinstead of Distributor Id: Ubuntu
例如。它显示Ubuntu而不是Distributor Id: Ubuntu
There are other options:
还有其他选择：
-r : release
-d : description
-c : codename
-a : all
-r : 释放
-d : 描述
-c : 代号
-a : 全部
You can get this information by running lsb_release --helpor man lsb_release
您可以通过运行lsb_release --help或man lsb_release

DISTRO=$( cat /etc/*-release | tr [:upper:] [:lower:] | grep -Poi '(debian|ubuntu|red hat|centos|nameyourdistro)' | uniq )
if [ -z $DISTRO ]; then
DISTRO='unknown'
fi
echo "Detected Linux distribution: $DISTRO"

Here is what i get:
这是我得到的：
#!/bin/bash
dist=$(tr -s ' 1' '2' < /etc/issue | head -n 1)
check_arch=$(uname -m)
echo "[$green+$txtrst] Distribution Name: $dist"

For almost all linux distros, cat /etc/issuewill do the trick.
对于几乎所有的 linux 发行版，cat /etc/issue都可以解决问题。
Edit: Obviously, no solution can apply to all distros, as distros are freeto do as they please.
编辑：显然，没有解决方案可以适用于所有发行版，如安装都是免费做的，因为他们请。
Further clarification: This is not guaranteed to work - nothing is - but in my experience, this is the method that most often works. Actually, it's the onlymethod that works consistently (lsb_release, which was mentioned here, often produces command not found).
进一步说明：这不能保证有效 - 没有什么是 - 但根据我的经验，这是最常用的方法。实际上，它是唯一能始终如一地工作的方法（lsb_release此处提到的 ，通常会产生command not found）。

I'd use uname -a

robert@debian:/tmp$ uname -a
Linux debian 3.2.0-4-686-pae #1 SMP Debian 3.2.65-1+deb7u2 i686 GNU/Linux
