Ubuntu 安裝 RAR 解壓縮程式

-
RAR 是屬於 non-free 的套件, 所以預設 apt 是找不到的.

不修改 /etc/sources.list 就想直接安裝, 最簡單的方法就是到 WinRAR 的官方網站下載 Linux 版本的 unrar 就可以囉~

安裝步驟

1. wget http://www.rarlab.com/rar/rarlinux-3.9.b3.tar.gz

2. tar zxvf rarlinux-3.9.b3.tar.gz

3. cd rar; cp rar /usr/bin; cp unrar /usr/bin

4. 測試: unrar x xxx.rar

We don't like the idea of renaming the actual file for the sake of supporting in Windows. We will look into alternatives and track this as an enhancement separately.  2.  Edit tarfile.py :  You should add a line in 2155  # targetpath_s = targetpath.replace(':','-')
