Before you make a concrete summary of the various types of compressed files, first understand two concepts: packaging and compression. Packing refers to the
A large pile of files or directories into a total file, compression is a large file through some pressure
The shrink algorithm becomes a small file. Why should we distinguish between these two concepts? It's actually a lot of pressure from Linux.
A shrink program can compress only one file, so that when you want to compress a bunch of files, you have to use
The other tool will make this large pile of files into a package, and then the original compression program to compress.

The most commonly used packaging program in Linux is tar, and the packages we use in the TAR program are often called tar packs.
, the commands for the tar package file usually end with. Tar. After the tar package is generated, you can use other programs to enter
Line is compressed, so let's start with the basic usage of the TAR command:

There are many options for the tar command (which can be viewed with man tar), but there are a few options that are commonly used, below
To illustrate:

# TAR-CF All.tar *.jpg
This command is to make all. jpg files into a package named All.tar. -C is to indicate the creation of a new package
,-f Specifies the file name of the package.

# TAR-RF All.tar *.gif
This command adds all the. gif files to the All.tar package. -R is the file that adds the
Mean.
# Tar-uf All.tar logo.gif
This command updates the logo.gif file in the original tar package All.tar, and-U is the meaning of the update file.


# TAR-TF All.tar
This command lists all the files in the All.tar package----------T is the list of files

# TAR-XF All.tar
This command is to solve all the files in the All.tar package------X is the meaning of the undo

The above is the most basic use of tar. In order to facilitate the packaging and unpacking of the user can be compressed or decompression
File, Tar provides a special feature. This is where tar can call other presses while packing or unpack.
Shrink programs, such as calling Gzip, bzip2, and so on.

1) Tar call gzip

Gzip is a compression program developed by the GNU organization, the file at the end of GZ is the result of gzip compression. With gzip
The relative decompression program is gunzip. Use the-Z parameter in tar to invoke gzip. Here are some examples to illustrate


# TAR-CZF all.tar.gz *.jpg
The command is to make all. jpg files into a tar package, and use gzip compression to generate a
Gzip compressed packets, package named all.tar.gz

# TAR-XZF All.tar.gz
This command is to untie the packets generated above.

2) Tar call bzip2

BZIP2 is a more compressed program,. bz2 end of the file is the result of bzip2 compression.
The bzip2 relative to the decompression program is BUNZIP2. Use-j this parameter in tar to invoke gzip. Here's an example.
Explain:

# TAR-CJF all.tar.bz2 *.jpg
The command is to make all. jpg files into a tar package and compress them with bzip2 to generate a
BZIP2 Compressed package named all.tar.bz2

# TAR-XJF ALL.TAR.BZ2
This command is to untie the packets generated above.
3) Tar call compress

Compress is also a compression program, but it seems that people who use compress are not as good as gzip and bzip2.
Many.. The file at the end of Z is the result of bzip2 compression. The decompression program relative to compress is uncompress
。 Use the-Z parameter in tar to invoke compress. Here are a few examples to illustrate:

# TAR-CZF All.tar.z *.jpg
The command is to make all. jpg files into a tar package and compress them with compress to generate
A uncompress compressed package named All.tar.z

# TAR-XZF All.tar.z
This command is to unlock the resulting package.

With the above knowledge, you should be able to unlock a variety of compressed files, the following for the TAR series of compressed text
Pieces to make a summary:

1 for. Tar End of File

TAR-XF All.tar

2 for. GZ End of File

Gzip-d all.gz
Gunzip all.gz

3. Documents ending with. tgz or. tar.gz

Tar-xzf all.tar.gz
Tar-xzf all.tgz

4 for. bz2 End of File

Bzip2-d all.bz2
BUNZIP2 all.bz2

5) For tar.bz2 end of file

TAR-XJF all.tar.bz2

6) for. File at the end of Z

Uncompress all. Z

7 for. Tar.z End of File

Tar-xzf All.tar.z

In addition to the common compressed files under Windows. zip and. Rar,linux also have a corresponding method to extract it
Children

1) for. zip

Linux provides a zip and unzip program, ZIP is a compression program, unzip is the decompression program. Their parameters
A lot of options, here is a simple introduction, still give an example to illustrate its use:

# Zip All.zip *.jpg
This command compresses all. jpg files into a zip package
# Unzip All.zip
This command is to extract all the files in the All.zip

2) for. rar

To process A. rar file under Linux, you need to install RAR for Linux, which you can download from the Internet, but remember
Live, RAR for Linux
Not free; Rarfor Linux 3.2 can be downloaded from http://www.rarsoft.com/download.htm.
0, and then install:

# TAR-XZPVF Rarlinux-3.2.0.tar.gz
# CD RAR
# make

This is installed, installed after the RAR and unrar these two programs, RAR is a compression program, Unrar
is the decompression program. They have a lot of parameter options, here is a simple introduction, still give examples of its use:


# rar a All *.jpg
This command compresses all. jpg files into a RAR package named All.rar, which will. rar
The extension name is automatically appended to the package name.

# Unrar E All.rar
This command is to extract all the files in the All.rar

As of this, we have introduced the TAR, gzip, gunzip, bzip2, BUNZIP2, compress under Linux
, uncompress, zip, unzip, RAR, Unrar, and so on, you should already be able to use them for. Tar
,. GZ,. tar.gz,. tgz,. bz2,. tar.bz2,. Z,. Tar. Z,. zip,. rar, 10 kinds of compressed text
Pieces to unpack, you should not need to download a software and do not know how to untie under Linux annoying
Annoyed. And the above method is also basically effective for UNIX.

This article describes the Linux compression program tar, gzip, gunzip, bzip2, BUNZIP2, compress
, uncompress, zip, unzip, RAR, Unrar, and how to use them for. Tar,. gz
,. tar.gz,. tgz,. bz2,. tar.bz2,. Z. Tar. Z,. zip,. rar, these 10 compressed files are
Operation.
