终端中的文件管理器ranger【视频】

自从用了vim后，感觉到了终端中的应用程序也可以有类似于图形化的操作和鼠标支持。无论是谁，在使用电脑的时候总是离不开文件操作的，那么有没有什么简单易用的类似于图形化的文件管理工具呢？

ranger 安装

在archlinux中安装

sudo pacman -S  --noconfirm ranger

安装依赖

sudo pacman -S  --noconfirm libcaca highlight atool lynx w3m elinks  mediainfo

在macOS中安装 安装ranger，可以使用基本的功能

brew install ranger

安装依赖，这样可以使用一些扩展的功能,主要是预览相关的。

brew install libcaca highlight atool lynx w3m elinks poppler transmission mediainfo exiftool

在CentOS中安装 稍微麻烦一些，另开一篇文章。 《CentOS安装Ranger》 https://blog.csdn.net/lxyoucan/article/details/115699624

使用

• 支持鼠标操作
• 文本文件上按回车可以直接打开vim编辑文件
• 响应非常快，非常快

配置ranger使其支持图片浏览 创建imgcat

vim imgcat

并写入以下内容：

#!/bin/bash

# tmux requires unrecognized OSC sequences to be wrapped with DCS tmux;
#  ST, and for all ESCs in  to be replaced with ESC ESC. It
# only accepts ESC backslash for ST. We use TERM instead of TMUX because TERM
# gets passed through ssh.
