篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了教你Centos7中使用7zip压缩工具相关的知识,希望对你有一定的参考价值。
环 境
-
Centos 7.7 Minimal -
p7zip-16.02
安 装
默认Centos7没有安装p7zip安装包,默认源里面也没有这个安装包,需要安装epel源才能安装p7zip安装包。
[root@localhost ~]# yum -y install epel-release
[root@localhost ~]# yum -y install p7zip p7zip-plugins
<以上代码可复制粘贴,可往左滑>
使用方法
7z命令提供的函数字母与命令行选项类似,但使用时不使用-。这些参数字母告诉命令它需要执行的函数。
压缩文件
创建一个压缩包使用a参数
创建一个7z格式的压缩包:
[root@localhost ~]# 7z a files.7z file1.txt file2.txt file3.txt file4.txt
7-Zip [64] 16.02 : Copyright (c) 1999-2016 Igor Pavlov : 2016-05-21
p7zip Version 16.02 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,64 bits,1 CPU Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz (906EA),ASM,AES-NI)
Scanning the drive:
4 files, 0 bytes
Creating archive: files.7z
Items to compress: 4
Files read from disk: 0
Archive size: 143 bytes (1 KiB)
Everything is Ok
执行完命令,查看一下是否已经创建7z格式的压缩包
创建一个包含目录的压缩包:
[root@localhost ~]# 7z a gpg.7z .gnupg/
7-Zip [64] 16.02 : Copyright (c) 1999-2016 Igor Pavlov : 2016-05-21
p7zip Version 16.02 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,64 bits,1 CPU Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz (906EA),ASM,AES-NI)
Scanning the drive:
2 folders, 5 files, 8280 bytes (9 KiB)
Creating archive: gpg.7z
Items to compress: 7
Files read from disk: 2
Archive size: 4157 bytes (5 KiB)
Everything is Ok
[root@localhost ~]#
7zip还可以压缩、解压缩其他格式的压缩包。比如:创建一个.zip格式的压缩包。
[root@localhost ~]# 7z a files.zip file{1..4}.txt
7-Zip [64] 16.02 : Copyright (c) 1999-2016 Igor Pavlov : 2016-05-21
p7zip Version 16.02 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,64 bits,1 CPU Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz (906EA),ASM,AES-NI)
Scanning the drive:
4 files, 0 bytes
Creating archive: files.zip
Items to compress: 4
Files read from disk: 4
Archive size: 542 bytes (1 KiB)
Everything is Ok
列出压缩包的内容使用l参数:
[root@localhost ~]# 7z l gpg.7z
7-Zip [64] 16.02 : Copyright (c) 1999-2016 Igor Pavlov : 2016-05-21

Scanning the drive for archives:

--

现在使用x参数解压文件看一下。
[root@localhost test]# 7z x gpg.7z

更新压缩包
一段时间之后,需要将一些新文件添加到文件夹中,并且希望将他们添加到压缩包里面,可以不用创建一个新的压缩包,只需要更新现有的压缩包就可以。
首先将test目录压缩
[root@localhost test]# 7z a files.7z test/
7-Zip [64] 16.02 : Copyright (c) 1999-2016 Igor Pavlov : 2016-05-21
p7zip Version 16.02 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,64 bits,1 CPU Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz (906EA),ASM,AES-NI)
Scanning the drive:
1 folder, 4 files, 0 bytes
Creating archive: files.7z
Items to compress: 5
Files read from disk: 0
Archive size: 158 bytes (1 KiB)
Everything is Ok
在test文件夹中创建几个文件,然后再更新压缩包:
[root@localhost test]# touch test/file{5..10}.txt
[root@localhost test]# 7z u files.7z test/
7-Zip [64] 16.02 : Copyright (c) 1999-2016 Igor Pavlov : 2016-05-21
p7zip Version 16.02 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,64 bits,1 CPU Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz (906EA),ASM,AES-NI)
Open archive: files.7z
--
Path = files.7z
Type = 7z
Physical Size = 158
Headers Size = 158
Solid = -
Blocks = 0
Scanning the drive:
1 folder, 10 files, 0 bytes
Updating archive: files.7z
Items to compress: 7
Files read from disk: 0
Archive size: 186 bytes (1 KiB)
Everything is Ok
[root@localhost test]# 7z l files.7z
