在Unix/Linux平台上查找操作系统名称和版本的最佳方法 [英] Best way to find os name and version in Unix/Linux platform

问题描述

我需要在Unix/Linux平台上找到操作系统名称和版本.为此，我尝试了以下操作:

I need to find the OS name and version on Unix/Linux platform. For this I tried following:

1. lsb_release实用程序

/etc/redhat-release或特定文件

但这似乎不是最好的解决方案，因为RHEL 7不再支持LSB_RELEASE.

But it does not seem to be best solution as LSB_RELEASE support is no longer for RHEL 7.

在任何Unix或Linux平台上都可以使用任何方法吗?

Is there any way that will work on any Unix or Linux platform?

推荐答案

此功能在所有Linux环境下都能正常工作.

This work fine for all Linux environment.

#!/bin/sh
cat /etc/*-release

在Ubuntu中:

$ cat /etc/*-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=10.04
DISTRIB_CODENAME=lucid
DISTRIB_DESCRIPTION="Ubuntu 10.04.4 LTS"

或12.04:

$ cat /etc/*-release

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=12.04
DISTRIB_CODENAME=precise
DISTRIB_DESCRIPTION="Ubuntu 12.04.4 LTS"
NAME="Ubuntu"
VERSION="12.04.4 LTS, Precise Pangolin"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu precise (12.04.4 LTS)"
VERSION_ID="12.04"

在RHEL中:

$ cat /etc/*-release
Red Hat Enterprise Linux Server release 6.5 (Santiago)
Red Hat Enterprise Linux Server release 6.5 (Santiago)

或使用此脚本:

#!/bin/sh
# Detects which OS and if it is Linux then it will detect which Linux
# Distribution.

OS=`uname -s`
REV=`uname -r`
MACH=`uname -m`

GetVersionFromFile()
{
    VERSION=`cat $1 | tr "\n" ' ' | sed s/.*VERSION.*=\ // `
}

if [ "${OS}" = "SunOS" ] ; then
    OS=Solaris
    ARCH=`uname -p` 
    OSSTR="${OS} ${REV}(${ARCH} `uname -v`)"
elif [ "${OS}" = "AIX" ] ; then
    OSSTR="${OS} `oslevel` (`oslevel -r`)"
elif [ "${OS}" = "Linux" ] ; then
    KERNEL=`uname -r`
    if [ -f /etc/redhat-release ] ; then
        DIST='RedHat'
        PSUEDONAME=`cat /etc/redhat-release | sed s/.*\(// | sed s/\)//`
        REV=`cat /etc/redhat-release | sed s/.*release\ // | sed s/\ .*//`
    elif [ -f /etc/SuSE-release ] ; then
        DIST=`cat /etc/SuSE-release | tr "\n" ' '| sed s/VERSION.*//`
        REV=`cat /etc/SuSE-release | tr "\n" ' ' | sed s/.*=\ //`
    elif [ -f /etc/mandrake-release ] ; then
        DIST='Mandrake'
        PSUEDONAME=`cat /etc/mandrake-release | sed s/.*\(// | sed s/\)//`
        REV=`cat /etc/mandrake-release | sed s/.*release\ // | sed s/\ .*//`
    elif [ -f /etc/debian_version ] ; then
        DIST="Debian `cat /etc/debian_version`"
        REV=""

    fi
    if [ -f /etc/UnitedLinux-release ] ; then
        DIST="${DIST}[`cat /etc/UnitedLinux-release | tr "\n" ' ' | sed s/VERSION.*//`]"
    fi

    OSSTR="${OS} ${DIST} ${REV}(${PSUEDONAME} ${KERNEL} ${MACH})"

fi

echo ${OSSTR}
