# linux常用命令和操作技巧
|
||
|
||
---
|
||
|
||
## 查看linux发行版本
|
||
|
||
- centos
|
||
|
||
```bash
|
||
rpm -q centos-release
|
||
```
|
||
|
||
结果大概如下：
|
||
|
||
centos-release-7-9.2009.1.el7.centos.x86_64
|
||
|
||
- ubuntu
|
||
|
||
```bash
|
||
lsb_release -a
|
||
```
|
||
|
||
## 查看本机的公网IP
|
||
|
||
```bash
|
||
curl cip.cc
|
||
```
|
||
|
||
## 用curl下载文件（不需要单独安装wget）
|
||
|
||
```bash
|
||
curl http://domain/path -L -O
|
||
```
|
||
|
||
将会在path的最后一段作为文件名来保存文件
|
||
|
||
```bash
|
||
curl http://domain/path -L -o filename
|
||
```
|
||
|
||
将会以filename为文件名保存文件
|
||
|
||
## centos系统临时切换成英文/中文
|
||
|
||
```bash
|
||
export LANG=en_US.UTF-8
|
||
```
|
||
|
||
```bash
|
||
export LANG=zh_CN.UTF-8
|
||
```
|
||
|
||
## ll按时间或大小排序
|
||
|
||
```bash
|
||
# 按时间降序（最新的在最后）
|
||
ll -rt
|
||
# 按大小降序（最小的在最后）
|
||
ll -Sh
|
||
```
