背景
代码语言:javascript复制前几日,需要从线上环境拉取部分数据导入到实验库,将工作告知运维后,运维发给我一个
xxx7z.001
xxx7z.002
xxx7z.003
xxx7z.004
看到这个第一眼,不知道怎么处理了,最后运维告知需要使用7za工具处理。为了巩固自己所学,下面开始研究下这个软件工具。
7-zip简介
7-zip以高压缩率著称,并且是一款免费开源的压缩软件。在常规的Linux发行版中,无法通过简单的yum命令来安装该软件。那么在CentOS中,如何安装7ZIP呢(其他环境或者小工具可以百度下哈)?
7-zip安装
M1 Linux源码编译安装
官网下载地址:http://www.7-zip.org/download.html 最新的版本为22.01。
安装比较简单,依次执行以下命令下载安装:
代码语言:javascript复制wget http://nchc.dl.sourceforge.net/project/p7zip/p7zip/9.20.1/p7zip_9.20.1_src_all.tar.bz2
tar -jxvf p7zip_9.20.1_src_all.tar.bz2
cd p7zip_9.20.1
make
make install
最后一步make install
后出现以下信息,即为安装完毕。
./install.sh /usr/local/bin /usr/local/lib/p7zip /usr/local/man /usr/local/share/doc/p7zip
● installing /usr/local/bin/7za
● 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
M2 Linux(rpm)安装
下载地址:http://pkgs.repoforge.org/p7zip/,请以最新版为准。
在 CentOS 5.x 32位下安装7ZIP
代码语言:javascript复制wget http://pkgs.repoforge.org/p7zip/p7zip-9.20.1-1.el5.rf.i386.rpm
rpm -ivh p7zip-9.20.1-1.el5.rf.i386.rpm
在 CentOS 5.x 64位下安装7ZIP
代码语言:javascript复制wget http://pkgs.repoforge.org/p7zip/p7zip-9.20.1-1.el5.rf.x86_64.rpm
rpm -ivh p7zip-9.20.1-1.el5.rf.x86_64.rpm
在 CentOS 6.x 32位下安装7ZIP
代码语言:javascript复制wget http://pkgs.repoforge.org/p7zip/p7zip-9.20.1-1.el6.rf.i686.rpm
rpm -ivh p7zip-9.20.1-1.el6.rf.i686.rpm
在 CentOS 6.x 64位下安装7ZIP
代码语言:javascript复制wget http://pkgs.repoforge.org/p7zip/p7zip-9.20.1-1.el6.rf.x86_64.rpm
rpm -ivh p7zip-9.20.1-1.el6.rf.x86_64.rpm
M3 Linux(yum)安装
通过上面M2执行安装中,安装RHEL EPEL Repo后,即可使用yum安装7ZIP。 命令如下:
代码语言:javascript复制yum install -y p7zip
M4 MacOS(brew)安装
在macOS中安装就比较方便了,可以使用brew
工具来查找、安装、使用和卸载等操作。
- 【查找】
$ brew search 7zip
==> Formulae
7-zip 7zip p7zip zip
当然,搜索7z
也是可以的
$ brew search 7z
==> Formulae
7-zip 7zip p7zip
- 【安装】
$ brew install 7zip
==> Downloading https://downloads.sourceforge.net/project/p7zip/p7zip/9.20.1/p7zip_9.20.1_src_all.tar.bz2
######################################################################## 100.0%
==> make all3 CC=clang $(ALLFLAGS) CXX=clang $(ALLFLAGS)
==> make DEST_HOME=/usr/local/Cellar/p7zip/9.20.1 DEST_MAN=/usr/local/Cellar/p7zip/9.20.1/share/man install
==> chmod -R w /usr/local/Cellar/p7zip/9.20.1/share/doc/p7zip
安装过程比较简单,安装后可以使用了。
M5 Windows(exe)中安装
在windows中就比较简单了,放一个下载连接即可:https://7-zip.org/download.html
注意⚠️:安装了不同的软件,使用命令可能不一样,例如7za
、7zz
等。
使用方法
使用7zip的命令是7za。安装完成后的使用方法:
- 「使用方法说明」
7za {a|d|l|e|u|x} 压缩包文件名 {文件列表或目录,可选}
其中,
- a :向压缩包里添加文件或创建压缩包。
- 如向001.7z添加001.jpg,执行:7za a 001.7z 001.jpg;将001目录打包执行:7za a 001.7z 001;
- d :从压缩里删除文件,如将001.7z里的001.jpg删除,执行:7za d 001.7z 001.jpg
- l :列出压缩包里的文件。
- 如列出001.7z里的文件,执行:7za l 001.7z
- e :解压到当前目录(不包含目录结构)。
- 目录结构会被破坏,如001.rar内有如下目录及文件123/456/789.html, 执行:7za e 001.rar,目录123和456及文件789.html都会存放在当前目录下。
- u :更新文件到压缩文件。
- x :以完整路径解压(包含目录结构)。
- zip文件解压中文文件乱码问题,由于zip文件中没有声明其编码,所以在Linux上使用unzip解压以默认编码解压,中文文件名会出现乱码。
帮助命令
当实在是不会使用的时候,尽量去百度,那里有你需要的答案。但是在没有网络的时候,就可以使用帮助命令来实现,例如
CentOS中使用帮助命令

写在最后
有些时候,有些命令,还是得看看,忘记的挺快,做笔记吧,让自己看上去不那么像一只摸鱼的兔子。
