FAQ unzip无法解压文件

[root@TEST144239 tmp]# unzip linx64_11gR2_database_1of2.zip
Archive:  linx64_11gR2_database_1of2.zip

  (attempting to process anyway)

导致解压不了,有两个可能因素:

1.zip文件,如果是从某个机器下载的,应该尽量保证是以 二进制编码方式下载,否则也会导致unzip 解压不了.

[root@ZTE-TEST144239 ~]# ftp 10.30.1.25

#确保文件是以二进制方式获得#
ftp> bin

ftp> get /public/数据库/ORACLE/11G/linux64/p10404530_112030_Linux-x86-64_1of7.zip /var/tmp/p10404530_112030_Linx-x86-64_1of7.zip

2.unzip命令不能解压超过2G的文件 通过查找资料有个7z的程序可以解压超过2G的压缩包

http://pkgs.repoforge.org/p7zip/  该地址下载7zip包

首先通过 file /bin/ls命令查看linux是32位还是64位:

[root@TEST144239 tmp]# file /bin/ls
/bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped

所以 下载并安装p7zip-9.04-1.el3.rf.x86_64.rpm和p7zip-plugins-9.04-1.el3.rf.x86_64.rpm这两个包:

[root@TEST144239 tmp]# rpm -ivh p7zip-9.04-1.el3.rf.x86_64.rpm
