linux 安裝p7zip 支援rar
7zip 9.20安裝後不支援rar格式的檔案，需附加安裝其他檔案，首先下載下傳2個源碼包
http://sourceforge.net/projects/p7zip/files/p7zip/9.20.1/
p7zip_9.20.1_src_all.tar.bz2 和 p7zip_9.20.1_x86_linux_bin.tar.bz2
先将p7zip_9.20.1_src_all.tar.bz2解壓，進入解壓後的檔案夾p7zip_9.20.1中
執行./install.sh 指令後出現一下提示表示安裝成功
linux 安裝p7zip 支援rar - wpjamer 這時p7zip已經安裝完成，可以運作7za指令，但7za指令無法解壓rar檔案，還需要安裝另一個源碼包：
在解壓p7zip_9.20.1_x86_linux_bin.tar.bz2，此時會預設将這個包裡的内容也解壓到p7zip_9.20.1檔案夾中
這時p7zip_9.20.1檔案夾中會多出一個bin目錄，安裝bin/Codecs/Rar29.so
或者将p7zip_9.20.1_x86_linux_bin.tar.bz2解壓出來的檔案夾(可以删除之前解壓出來的7zip_9.20.1檔案夾)放到指定的軟體安裝目錄中，将bin目錄下的7z和7z.so檔案複制到/usr/sbin目錄中，此時就可以使用7z指令來解壓rar檔案了。
對于Window下的常見壓縮檔案.zip和.rar，Linux也有相應的方法來解壓它們：
1)對于.zip
linux下提供了zip和unzip程式，zip是壓縮程式，unzip是解壓程式。它們的參數選項很多，可用指令zip -help和unzip -help檢視，這裡隻做簡單介紹，舉例說明一下其用法：
# zip yajiu.zip yajiu.jpg yajiu.png
這條指令是将yajiu.jpg和yajiu.png壓縮成一個zip包
# zip yajiu.zip *.jpg
這條指令是将所有.jpg的檔案壓縮成一個zip包
# zip -r yajiu.zip yajiu
這條指令是将檔案夾yajiu壓縮成一個zip包
# unzip yajiu.zip
這條指令是将yajiu.zip中的所有檔案解壓出來

2)對于.rar
安裝： sudo apt-get install rar unrar
或者可從http://www.rarsoft.com/download.htm下載下傳 RAR for Linux 編譯安裝
# tar -xzpvf rarlinux-3.8.0.tar.gz
# cd rar
# make
這樣就安裝好了，安裝之後就有了rar和unrar這兩個程式，rar是壓縮程式，unrar是解壓程式。它們的參數選項很多，可用指令rar -help和unrar -help檢視，這裡亦簡單舉例說明一下其用法：
# rar a yajiu.rar yajiu.jpg yajiu.png
這條指令是将yajiu.jpg和yajiu.png壓縮成一個rar包
# rar a yajiu.rar *.jpg
這條指令是将所有.jpg的檔案壓縮成一個rar包
# rar a yajiu.rar yajiu
這條指令是将檔案夾yajiu壓縮成一個rar包
# unrar e yajiu.rar
這條指令是将yajiu.rar中的所有檔案解壓出來
