Package and compress files or directories under Linux

One, compression command [COMPRESS/GZIP/BZIP2]:

Compression can only be done on files, not directories, directories to be packaged first, and then compressed.

(1) Compress

(2) Gzip

1. Compress files

[CPP]View PlainCopy

1. Gzip hosts #将hosts压缩成hosts. GZ, do not retain the original file
2. Gzip-c hosts > Xx/hosts.gz #将hosts压缩成hosts. GZ, preserves the original file, and can also specify a path

2. View Compressed file contents

[CPP]View PlainCopy

1. Zcat hosts.gz

3. Decompression

[CPP]View PlainCopy

1. Gzip-d hosts.gz #不指定路径的解压, unzip to the current directory, do not retain the compressed file
2. Gzip-d-C hosts.gz > Xx/hosts #指定路径的解压 while preserving compressed files

(3) bZIP

1. Compress files

[CPP]View PlainCopy

1. Bzip2 hosts.bz2 #将hosts压缩成hosts. bz2, do not keep the original file
2. Bzip2-c hosts > xx/hosts.bz2 #将hosts压缩成hosts. GZ, retains the original file, and can also specify the path <span style="FONT-SIZE:18PX;" >
3. </span>

2. View Compressed file contents

[CPP]View PlainCopy

1. Bzcat hosts.bz2

3. Decompression

[CPP]View PlainCopy

1. Bzip2-d hosts.bz2 #不指定路径的解压, unzip to the current directory, do not retain the compressed file
2. Bzip2-d-C hosts.bz2 > Xx/hosts #指定路径的解压 while preserving compressed files

Summarize:

-C: Specify path, keep file

-D: Unzip

gzip, bzip2 default does not retain the original file/compressed file.

Ii. Packing/compressing commands [tar]

2.1 Packing/Unpack:

(1) Package a single file

[CPP]View PlainCopy

1. Tar cvf aa.tar AA #默认保留原文件
2. Tar cvf aa.tar aa--remove-file #打包后删除原文件

(2) Packaging multiple files

[CPP]View PlainCopy

1. Tar cvf ab.tar aa bb #默认保留原文件
2. Tar cvf aa.tar aa bb--remove-file #打包后删除原文件

(3) View the contents of the package

[CPP]View PlainCopy

1. Tar TVF Aa.tar

(4) Unpacking

[CPP]View PlainCopy

1. Tar xvf Aa.tar #不指定路径的解包, unpack to current directory
2. Tar xvf aa.tar-c xx/aa #指定路径的解包

2.2 Package and compress/unzip and unpack:

In gzip format

(1) Package a single file and compress

[CPP]View PlainCopy

1. Tar zcvf aa.tar.gz AA #保留原文件
2. Tar zcvf aa.tar.gz aa--remove-file #不保留原文件

(2) Packaging multiple files and compressing

[CPP]View PlainCopy

1. Tar zcvf ab.tar.gz aa bb #保留原文件
2. Tar zcvf ab.tar.gz aa bb--remove-file #不保留原文件

(3) Decompression

[CPP]View PlainCopy

1. Tar zxvf ab.tar.gz #不指定路径解压, unpacking
2. Tar zxvf ab.tar.gz-c xx/ab #指定路径解压, unpacking

In BIZP2 format

(1) Package a single file and compress

[CPP]View PlainCopy

1. Tar jcvf aa.tar.bz2 AA #保留原文件
2. Tar jcvf aa.tar.bz2 aa--remove-file #不保留原文件

(2) Packaging multiple files and compressing

[CPP]View PlainCopy

1. Tar jcvf ab.tar.bz2 aa bb #保留原文件
2. Tar jcvf ab.tar.bz2 aa bb--remove-file #不保留原文件

(3) Decompression

[CPP]View PlainCopy

1. Tar jxvf ab.tar.bz2 #不指定路径解压, unpacking
2. Tar jxvf ab.tar.bz2-c xx/ab #指定路径解压, unpacking

Summarize:

-C: Specify the path

--remove-file: Delete the original file

The tar command retains the original file by default.
