1.文件归档
文件归档，就是把多个文件变成一个归档文件
2.tar命令
tar c ##创建
[root@localhost ~]# tar cf /mnt/etc.tar /etc/
tar: Removing leading `/' from member names
[root@localhost ~]# ls /mnt/
etc.tar file
f ##指定归档文件名称
t ##显示归档文件中的内容
[root@localhost ~]# tar ft /mnt/etc.tar

r ##向归档文件中添加文件
--get ##取出单个文件
--delete ##删除单个文件
x ##取出归档文件中的所有内容
-C ##指定解档目录
-z ##gz格式压缩
-j ##bz2格式压缩
-J ##xz格式压缩
2.压缩
gz
gzip etc.tar ##压缩成gz格式
gunzip etc.tar.gz ##解压gz格式压缩包
tar zcf etc.tar.gz /etc ##把文件归档为tar并压缩成gz
tar zxf etc.tar.gz ##解压并解档gz格式压缩包
bz2
bzip2 etc.tar ##压缩成bz2格式
bunzip2 etc.tar.bz2 ##解压bz2格式压缩包
tar jcf etc.tar.bz2 /etc ##把文件归档为tar并压缩成bz2
tar jxf etc.tar.bz2 ##解压并解档bz2格式压缩包
xz
xz etc.tar ##压缩成xz格式
unxz etc.tar.xz ##解压xz格式压缩包
tar Jcf etc.tar.xz /etc ##把文件归档为tar并压缩成zx
tar Jxf etc.tar.xz ##解压并解档xz格式压缩包
zip
zip -r etc.tar.zip etc.tar ##压缩成zip格式
unzip etc.tar.zip ##解压zip格式压缩包
3.系统中的文件传输
scp file username@ip:/dir ##上传
scp username@ip:/dir/file /dir ##下载
[root@localhost ~]# scp * [email protected]:/mnt/
