Basic Linux Learning (eight)

In this chapter, we learn about file archiving, compression, transmission, and network management.

# #文件的归档

1. File archiving is to turn multiple files into an archive file

TAR-C # #创建

-F # #指定归档文件名称

-T # #显示归档文件中的内容

-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

From this we can see that the commonly used compression has three ways: gz,bz2,xz

2. Compression

Gz

Gzip Etc.tar # #压缩成gz格式

Gunzip etc.tar.gz # #解压gz格式压缩包

Tar file Etc.tar.gz/etc # #把文件归档为tar并压缩成gz文件

Tar file 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 file etc.tar.bz2 # # archive files as tar and compress them into bz2 files

tar file 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 file Etc.tar.xz/etc # #把文件归档为tar并压缩成xz文件

Tar file Etc.tar.xz # #解压并解档xz格式压缩包

# #系统中的文件传输

SCP file [email protected]:/dir # #上传

SCP [email Protected]:/dir/file/dir # #下载

rsync [parameter] file [email protected]:/dir

-R # #同步目录

-L # #不忽略连接

-P # #不忽略文件权限

-T # #不忽略文件时间戳

-G # #不忽略文件所有组

-O # #不忽略文件所有人

-D # #不忽略设备文件

SCP vs. Rsync, the rsync approach is much faster than the SCP approach

# #网络管理

Two ways to view network status: Ifconfig|ip addr Show

1. IP Fundamentals

IPv4

172.25.0.10/255.255.255.0

172.25.0.10:ip Address

255.255.255.0: Subnet Mask

Subnet mask 255-bit corresponding IP bit for network bit

Subnet mask 0 corresponds to the IP bit master camera

2. Configure IP
