在CLI上将ISO文件提取为非root用户

将p7zip安装到您自己的帐户中不需要任何额外的特权。从此处下载p7zip二进制tarball，将其解压缩，然后从其随附的bin目录中运行7z。

从我不使用root特权的我的Ubuntu系统中：

user@host:~/Inbox/p7zip_9.20.1/bin$ ./7z

7-Zip 9.20  Copyright (c) 1999-2010 Igor Pavlov  2010-11-18
p7zip Version 9.20 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,2 CPUs)

Usage: 7z <command> [<switches>...] <archive_name> [<file_names>...]

<Commands>
  a: Add files to archive
...
  -y: assume Yes on all queries
user@host:~/Inbox/p7zip_9.20.1/bin$ 

全新安装Debian的完整示例，以防万一（使用7z，不使用7za）：

renfro@itchy:~$ ls
debian-6.0.4-amd64-netinst.iso  p7zip.tar.bz2
renfro@itchy:~$ tar -jxf p7zip.tar.bz2
renfro@itchy:~$ ls
debian-6.0.4-amd64-netinst.iso  p7zip_9.20.1  p7zip.tar.bz2
renfro@itchy:~$ p7zip_9.20.1/bin/7z x debian-6.0.4-amd64-netinst.iso
