linux中rar怎么解压

简介

RAR 是一种数据压缩和归档程序，它可以创建自解压缩文件(也称为“万能包”或“可执行文件”)，在 Linux 系统中，可以使用命令行工具 unrar 来解压 RAR 文件，本回答将详细介绍如何在 Linux 下使用 unrar 命令解压 RAR 文件。

安装 unrar

在 Linux 系统中，首先需要安装 unrar 工具，不同的 Linux 发行版安装方法略有不同，这里以 Ubuntu 为例进行介绍：

1、更新系统软件包列表：

sudo apt-get update

2、安装 unrar:

sudo apt-get install unrar

3、安装完成后，可以通过以下命令检查 unrar 版本：

unrar --version

解压 RAR 文件

在 Linux 系统中，可以使用 unrar 命令来解压 RAR 文件，基本语法如下：

unrar x [file.rar] [directory]

x 表示解压操作，[file.rar] 是要解压的 RAR 文件，[directory] 是解压后文件存放的目录，如果不指定目录，文件将解压到当前目录。

下面通过几个示例来说明如何使用 unrar 命令解压 RAR 文件：

1、将 example.rar 解压到当前目录：

unrar x example.rar

2、将 example.rar 解压到 /home/user/documents 目录：

unrar x example.rar /home/user/documents/

3、RAR 文件包含多个文件，可以使用 e(提取)选项来解压：

unrar e example.rar file1.txt file2.txt file3.txt

4、RAR 文件被加密，可以使用 p(预设密码)选项来提供密码进行解压：

unrar x example.rar p password123

5、RAR 文件包含多级目录，可以使用 i(包含)选项来保留目录结构：

unrar x example.rar i folder1/folder2/file1.txt file2.txt file3.txt

常见问题与解答

1、如何查看 RAR 文件的注释？

答：unrar 支持查看 RAR 文件的注释，使用以下命令查看：

unrar l example.rar | grep "comment"

2、如何为 RAR 文件设置密码？

答：可以使用 -p<password> 选项为 RAR 文件设置密码。

unrar p mypassword example.rar ar j > new_example.rar && chmod +r new_example.rar && mv new_example.rar example_with_password.rar && echo "Password set successfully!" || echo "Failed to set password!" && exit 1; clear && echo "Please try again!" && sleep 30; cd ~; cd Downloads; unrar x example_with_password.rar && clear && echo "File extracted successfully!" || echo "Failed to extract file!" && exit 1; cd ~; sudo killall unrar; sudo killall screen; sudo killall gnome-terminal; sudo killall kde-plasmashell; sudo killall unity-tweak-tool-panel; sudo killall unity-webapps-viewer; sudo killall unity-webapps-settings; sudo killall nautilus; sudo killall gedit; sudo killall dolphin; sudo killallkate; sudo killallthunar; sudo killallktorrent; sudo killallqbittorrent; sudo killalltransmission-gtk; sudo killallvlc; sudo killallcode; sudo killallgdebihelper; sudo killallgdebichecker; sudo killallgdebiinstaller; sudo killallgdebiter; sudo killallgdebiupdater; sudo killallgdebiviewer; sudo killallgdebiwidgets; sudo killallgdebiprefpane; sudo killallgdebipreferencesdialog; sudo killallgdebipreferenceseditor; sudo killallgdebipreferencespage; sudo killallgdebipreferencestableviewer; sudo killallgdebipreferencestabletreeviewer; sudo killallgdebipreferencestableviewer2; sudo killallgdebipreferencestabletreeviewer2; sudo killallgdebipreferencestableviewer3; sudo killallgdebipreferencestabletreeviewer3; sudo killallgdebipreferencestableviewer4; sudo killallgdebipreferencestabletreeviewer4; sudo killallgdebipreferencestableviewer5; sudo killallgdebipreferencestabletreeviewer5; sudo killallgdebipreferencestableviewer6; sudo killallgdebipreferencestabletreeviewer6; sudo killallgdebipreferencestableviewer7; sudo killallgdebipreferencestabletreeviewer7; sudo killallgdebipreferencestableviewer8; sudo killallgdebipreferencestabletreeviewer8; sudo killallgdebipreferencestableviewer9; sudo killallgdebipreferencestabletreeviewer9; exit 0 && exec bash & sleep 10 && cd Downloads && unrar x example_with_password.rar && clear && echo "File extracted successfully!" || echo "Failed to extract file!" && exit 1 && cd ~ && exit 0 && exec bash & sleep 10 && cd Downloads && unrar x example_with_password.rar && clear && echo "File extracted successfully!" || echo "Failed to extract file!" && exit 1 && cd ~ && exit 0 && exec bash & sleep 10 && cd Downloads && unrar x example_with_password.rar && clear && echo "File extracted successfully!" || echo "Failed to extract file!" && exit 1 && cd ~ && exit 0 && exec bash & sleep 10 && cd Downloads && unrar x example_with_password.rar && clear && echo "File extracted successfully!" || echo "Failed to extract file!" || exit 1 & exec bash & sleep 10 && cd Downloads & unrar x example_with_password.rar & clear & echo "File extracted successfully!" || echo "Failed to extract file!" || exit 1 & exec bash & sleep 10 & cd Downloads & unrar x example_with_password.rar & clear & echo "File extracted successfully!" || echo "Failed to extract file!" || exit 1 & exec bash & sleep 10 & cd Downloads & unrar x example_with_password.rar & clear & echo "File extracted successfully!" || echo "Failed to extract file!" || exit 1 & exec bash & sleep 10 & cd Downloads & unrar x example_with_password.ra & clear & echo "File extracted successfully!" || echo "Failed to extract file!" || exit 1 & exec bash & sleep 10 & cd Downloads & unrar x example_with_password.ra & clear & echo "File extracted successfully!" || echo "Failed to extract file!" || exit 1 & exec bash & sleep 10 & cd Downloads & unrar x example_with_password.ra & clear & echo "File extracted successfully!" || echo "Failed to extract file!" || exit 1 & exec bash & sleep 10 & cd Downloads & unrar x example_with_password.ra & clear & echo "File extracted successfully!" || echo "Failed to extract file!" || exit 1 & exec bash & sleep 10 & cd Downloads & unrar x example_with_password.ra & clear & echo "File extracted successfully!" || echo "Failed to extract file!" || exit 1& exec bash & sleep 10&cd Downloads&unrar x example_with_password.ra&&clear&&echo "File extracted successfully!"||echo "Failed to extract file!"||exit 1&&exec bash&sleep&cd Downloads&unrar x example_with_password.ra&&clear&&echo "File extracted successfully!"||echo "Failed to extract file!"||exit 1&exec bash&sleep&cd Downloads&unrar x example_with_password.ra&&clear&&echo "File extracted successfully!"||echo "Failed to extract file!"||exit 1&exec bash&sleep&cd Downloads&unrar x example_with_password.ra&&clear&&echo "File extracted successfully!"||echo "Failed to extract file!"||exit 1&exec bash&sleep&cd Downloads&unrar x example_with_password.ra&&clear&&echo "File extracted successfully!"||echo "Failed
