输出信息为当前测试环境信息,命令只保证在当前系统环境有效

1. 查看系统内核信息

1 2	uname -a # Linux ip-172-31-22-34 4.4.0-1044-aws #53-Ubuntu SMP Mon Dec 11 13:49:57 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

2. 查看系统版本信息

1 2	cat /proc/version # Linux version 4.4.0-1044-aws (buildd@lgw01-amd64-013) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.5) ) #53-Ubuntu SMP Mon Dec 11 13:49:57 UTC 2017

3. 查看发行版信息

cat /etc/issue
