Compress and package CentOS documents.

Compress and package CentOS documents.

.Rarcompressed file is not identified in linux, and .zip can be used in windows and Linux.

. Gz: Files compressed by gzip

. Bz2: Files compressed by bzip2 compression Tool

. Tar: A file packaged by the tar package. (Tar does not have the compression function, but only combines a directory into a file ).

.Tar.gz: first pack tar and then compress it by gzip.

.Tar.bz2: first pack tar and then compress it with bzip2.

. Tar. xz: tar is first packaged and then compressed by xz.

Gzip compression tool (the directory cannot be compressed, and an error is reported)

Gzip [-d #] filename

-D: used for decompression.

-#: Indicates the compression level. 1 indicates the worst, 9 indicates the best, and 6 indicates the default value.

Gzip 1.txt is compressed to 1.txt.gz, and the original file disappears.

Decompress the gzip-d 1.txt.gz file and the original file disappears.

Bzip2 compression tool (directory cannot be compressed)

Install bzip2: yum install-y bzip2

Bzip2 [-dz] filename

-D: Extract

-Z: compression (can be compressed with or without it)

Bzip2-z 1.txt is compressed into 1.txt.bz2, and the original file disappears.

Bzip-d 1.txt.bz2 decompress the file and the original file disappears.

Zx compressed file usage is the same as bzip2

Tar packaging tool: tar [-zjJxcvfpP] filename tar

-Z: gzip compression at the same time

-J: bzip2 compression at the same time

-J: Use xz to compress data at the same time.

-X: Indicates decompression.

-T: view the files in the tar package.

-C: Create a tar package

-V: Indicates visualization and shows which files are packaged.

-F: the root file name, indicating the compressed file name or the decompressed file name. If multiple parameters are combined, write the-f parameter to the end.

-P: use the original file attribute, the attributes before compression, and the attributes after compression. (Not commonly used)

-P: You can use absolute paths (not commonly used)

Tar-cf test.tar t1.txt t2.txt tt pack t1.txt, t2.txt, and ttas into the test.tar file.

Tar-cvf test.tar t1.txt t2.txt tt package t1.txt, t2.txt, and ttles into the test.tar file and display the packaged file.

Packaging + gzip Compression

Compress tar-czvf test.tar.gz test123 test123into the test.tar.gz file.

-Tf option to view the list of packages or compressed files

Tar-tf test.tar.gz contains the file list of test.tar.gz.

-Zxvf: Decompress the compressed package in the .tar.gz format.

Tar-zxvf test.tar.gz unzip

Package + bzip2 Compression

Tar-cjvf test.tar.bz2 test123

Tar-tf test.tar.bz2.

Tar-jxvf test.tar.bz2 unzip the package.

Zip compression yum install-y zip

Zip 1.txt.zip 1.txt 1.txtcompressed to 1.txt.zip

Zip test.zip test1/* compresses all files in test1 (in fact, only the second-level directories can be compressed)

Zip-r test.zip test11/compress all files in test1, including directories or files in the second-level directory.

Decompress the zip file (yum install-y unzip)

Unzip 1.txt.zip
