Linux Learning Notes Lesson nineth compression Packaging

One, gzip tool

Second, bZIP tools

Three, XZ tools

Four, zip and unzip

V. Tar

I, Gzip and zcat (-D,-N)

[[Email protected] ~] #gzip-9 install.log//compression level 1~9,1-faster,9-better

-rw-r--r--. 1 root root 3719 March 9 10:58 install.log.gz

[[Email protected] ~] #gzip-D install.log.gz//-D or Gunzip unzip,

[Email protected] ~]# Zcat 1.txt.gz
This was only bzip2 test!

After gzip file, file files will become File.zip

II, BZIP2 and Bzcat (-d-n)

[Email protected] ~]# bzip2 Install.log

-rw-r--r--. 1 root root 3298 March 9 10:58 install.log.bz2

[Email protected] ~]# bzip2-d install.log.bz2

[[email protected] ~]# bzcat 1.txt.bz2//bzcat View content
This was only bzip2 test!

Iii. XZ and Xzcat Tools

[Email protected] ~]# XZ 1.txt//

[email protected] ~]# LL | grep 1.txt

-rw-r--r--. 1 root root 80 March 14:47 1.txt.xz

[Email protected] ~]# Xzcat 1.TXT.XZ
This was only bzip2 test!
[Email protected] ~]# xz-d 1.TXT.XZ

[email protected] ~]# LL | grep 1.txt
-rw-r--r--. 1 root root 24 March 14:47 1.txt

[Email protected] ~]# XZ 1.txt 2.txt

[email protected] ~]# LL
Total Dosage 36
-rw-r--r--. 1 root root 80 March 14:47 1.txt.xz
-rw-r--r--. 1 root root 80 March 14:57 2.txt.xz

[Email protected] ~]# xz-d 1.txt.xz 2.txt.xz
[email protected] ~]# LL
Total Dosage 36
-rw-r--r--. 1 root root 24 March 14:47 1.txt
-rw-r--r--. 1 root root 24 March 14:57 2.txt

Four, zip and unzip

Zip is a compression tool, unzip is the unzip tool

Compressed files:

[[email protected] ~]# zip txt.zip 1.txt 2.txt
Adding:1.txt (stored 0%)
Adding:2.txt (stored 0%)

[email protected] ~]# LL
-rw-r--r--. 1 root root 346 March 15:20 txt.zip

[[email protected] ~]# zip-r dir.zip dir1/etc//-R compression Directory

[[email protected] ~]# unzip-l dir1.zip//View the list of compressed packages

[Email protected] ~]# Unzip dir.zip-d/tmp

[Email protected] ~]# ll/tmp
Total Dosage 8
Drwxr-xr-x. 2 root root 4096 March 16:00 Dir1
Drwxr-xr-x. 16:00 root root 4096 March

Five, tar packaging tools

Syntax: tar [-JXCVFPP] File

Package: TAR-CVF

-C: Build package,-V visualization,-F file name

-T: View the contents of the TAR Package

-C: Unzip to the specified directory:

[Email protected] ~]# TAR-CVF All.tar dir1 dir.zip etc

[Email protected] ~]# tar-u DIR2-VF all.tar/u: Add a new file in the package

[[email protected] ~]# TAR-TF All.tar//-T view the files in the tar package

[[email protected] ~]# tar-c/TMP-XVF All.tar//C extract to the specified directory

1. Use gzip compression while packaging:

TAR-CZVF test.tar.gz Test

TAR-XZVF TEST.TAR.GZ-C/tmp/-C unpack the package to the TMP directory

2, packaging and use bzip2 compression

TAR-CJVF all.tar.bz2 All

TAR-XJVF ALL.TAR.BZ2-C/tmp

3. Use XZ compression while packaging

TAR-JCVF all.tar.xz Dir1 Dir2 etc//package Dir1 Dir2 and etc

TAR-JXVF ALL.TAR.XZ

[Email protected] ~]# TAR-JXVF ALL.TAR.XZ-C/tmp

[Email protected] ~]# ll/tmp

Total Dosage 12
Drwxr-xr-x. 2 root root 4096 March 15:57 Dir1
Drwxr-xr-x. 2 root root 4096 March 16:05 Dir2
Drwxr-xr-x. 15:57 root root 4096 March

4 、--exclude exclude certain files

Tar--exclude *.d-zcvf etc.tar.gz/etc

TAR-TF etc.tar.gz | More

Tar--exclude *.d--exclude *.CONF-ZCVF etc.tar.gz/etc
