linux下解压rar文件

原创 Linux操作系统 作者:regonly1 时间:2012-03-31 11:27:09 0 删除 编辑
rar是一个在windows下盛行的压缩格式,到了linux/unix环境下,却连找个解压缩的工具都很难找到。网上找了下,发现7zip可以用来解压这个。顺便记录下解决过程:
1、安装以下程序:
-rw-r--r--  1 root root     2152153 Mar 31 10:56 p7zip_9.20.1_x86_linux_bin.tar.bz2
-rw-r--r--  1 root root     3835235 Mar 31 10:56 p7zip_9.20.1_src_all.tar.bz2
2、分别解压得到:
p7zip_9.20.1目录
3、进入p7zip_9.20.1目录,安装:
[root@DB p7zip_9.20.1]# ./install.sh
- installing /usr/local/bin/7za
- installing /usr/local/bin/7zr
- installing /usr/local/bin/7z
- installing /usr/local/lib/p7zip/7zCon.sfx
- installing /usr/local/lib/p7zip/7z.so
- installing /usr/local/lib/p7zip/Codecs
- installing /usr/local/man/man1/7z.1
- installing /usr/local/man/man1/7za.1
- installing /usr/local/man/man1/7zr.1
- installing /usr/local/share/doc/p7zip/README
- installing /usr/local/share/doc/p7zip/ChangeLog
- installing HTML help in /usr/local/share/doc/p7zip/DOCS

总共有三类命令:7z 7zr 7za,作用:
  7z uses plugins (7z.so and Codecs/Rar29.so) to handle archives.
  7za is a stand-alone executable.
  7za handles less archive formats than 7z.exe.
  7zr is a light stand-alone executable that supports only 7z/LZMA/BCJ/BCJ2.

所以用7z来解压,先看下命令格式:
[root@DB p7zip_9.20.1]# 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 [...] [...]
       [<@listfiles...>]


  a: Add files to archive
  b: Benchmark
  d: Delete files from archive
  e: Extract files from archive (without using directory names)
  l: List contents of archive
  t: Test integrity of archive
  u: Update files to archive
  x: eXtract files with full paths

  -ai[r[-|0]]{@listfile|!wildcard}: Include archives
  -ax[r[-|0]]{@listfile|!wildcard}: eXclude archives
  -bd: Disable percentage indicator
  -i[r[-|0]]{@listfile|!wildcard}: Include filenames
  -m{Parameters}: set compression Method
  -o{Directory}: set Output directory
  -p{Password}: set Password
  -r[-|0]: Recurse subdirectories
  -scs{UTF-8 | WIN | DOS}: set charset for list files
  -sfx[{name}]: Create SFX archive
  -si[{name}]: read data from stdin
  -slt: show technical information for l (List) command
  -so: write data to stdout
  -ssc[-]: set sensitive case mode
  -t{Type}: Set type of archive
  -u[-][p#][q#][r#][x#][y#][z#][!newArchiveName]: Update options
  -v{Size}[b|k|m|g]: Create volumes
  -w[{path}]: assign Work directory. Empty path means a temporary directory
  -x[r[-|0]]]{@listfile|!wildcard}: eXclude filenames
  -y: assume Yes on all queries

起先以为这么解压就行了:
7z -e xx.rar
但是报:
[oracle@DB ~]$ 7z -e wind_20120101.rar


Error:
Incorrect command line
奇怪,难道跟正常的格式不一样么?所以又回过头去仔细学习了下命令格式。
重新再来:
[oracle@DB ~]$ 7z e -slt wind_20120101.rar

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

Processing archive: wind_20120101.rar

这下可以了。
