Question

为什么在ubuntu上没有-a参数的情况下不能运行lsb_release？因为当我运行lsb_release命令时，我收到消息“没有可用的LSB模块”。

Answer 1

说明： lsb_release命令-在计算机上打印Linux发行版。

解决方案：没有参数时，默认情况下为-v（版本）。要查看Linux发行版的完整信息，请始终使用-a标志或-r发行号。

示例：

$lsb_release -a

#output:
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.5 LTS
Release:    18.04
Codename:   bionic

$lsb_release -r

#output:
Release:    18.04

标志是：

       -v, --version
              Show the version of the LSB against which your current installation is compliant.  The version is expressed as a colon separated list of LSB module descriptions.

       -i, --id
              Display the distributor's ID.

       -d, --description
              Display a description of the currently installed distribution.

       -r, --release
              Display the release number of the currently installed distribution.

       -c, --codename
              Display the code name of the currently installed distribution.

       -a, --all
              Display all of the above information.

       -s, --short
              Use the short output format for any information displayed.  This format omits the leading header(s).

       -h, --help
              Show summary of options.

Answer 2

从man page到lsb_release：

   If no options are given, the -v option is assumed.

-v选项：

   -v, --version
          Show the version of the LSB against which your current installa‐
          tion  is  compliant.   The version is expressed as a colon sepa‐
          rated list of LSB module descriptions.

如果没有安装任何lsb模块，则会收到您所描述的消息。 -a开关显示所有可用信息。

为什么在ubuntu上不带-a参数就不能运行lsb_release？
