Linux工具

写在前面

Linux 上一些常用的工具。

例如：可以自动补全的 mysql 工具mycli，交互式搜索的fzf，代码统计工具cloc…

mycli

mycli

mysql 客户端，支持语法高亮和命令补全，运行在 Terminal 上。

mycli

fzf

fzf

命令行下模糊搜索工具，交互式智能搜索并选取文件或内容。

fzf

cloc

cloc

代码统计工具

cloc

ccache

Gentoo ccache

高速 C/C++编译缓存工具，提高编译速度。

gcc foo.c
ccache gcc foo.c

tmux

tmux

终端复用

tmux

tldr

tldr

简略的 man 文档

需要额外配置颜色输出
文件：~/.tldrrc

{
  "themes": {
    "my": {
      "commandName": "bold, cyan",
      "mainDescription": "underline",
      "exampleDescription": "yellow",
      "exampleCode": "red",
      "exampleToken": "dim"
    }
  },
  "theme": "my"
}

tldr

ranger

ranger

Terminal 上的文件系统。无桌面环境也能使用。

ranger

cpupower

限制 CPU 功率，降低功耗

查看支持的调度器：

cpupower frequency-info
analyzing CPU 5:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 5
  CPUs which need to have their frequency coordinated by software: 5
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 800 MHz - 4.00 GHz
  available cpufreq governors: performance powersave
  current policy: frequency should be within 800 MHz and 4.00 GHz.
                  The governor "performance" may decide which speed to use
                  within this range.
  current CPU frequency: Unable to call hardware
  current CPU frequency: 3.07 GHz (asserted by call to kernel)
  boost state support:
    Supported: yes
    Active: yes

从available cpufreq governors获取两种模式performance和powersave

限制最大频率（1.2GHz）：

sudo cpupower frequency-set -u 1200000
