2015.3.27 compression and packaging of Linux documents

1. Gzip tool does not support compression directory

Syntax: gzip [-d#] filename where # is a number 1-9, the default compression level is 6

Only files can be compressed

gzip filename generation filename.gz source file disappears

Unzip the gzip-d filename.gz and the compressed files will disappear.

2, bzip2 compression tool does not support compression directory

Syntax: bzip2 [-DZ] filename

Compression, you can add "-Z" can also not add, can be compressed files, bzip2 filename generated filename.bz2 source files disappear

Compression directory not supported

bzip2-d filename.bz2 compressed file disappears after decompression

You can use Bzcat to view the contents of bz2 files before compression

3, XZ does not support compression directory

Usage with gzip and bzip2

XZ filename

Generate FILENAME.XZ

xz-d Filename.xz extract xzcat filename View xz compressed file contents

4, Zip and unzip

Zip is a compression tool, unzip is the unzip tool

Compressed files: Zip filename.zip filename

Extract directory: Zip-r dir.zip dir/

Unzip Zip package: Unzip Filename.zip

Unzip-l Filename.zip lists the list of files in the zipped package

Unzip-d/tmp/filename.zip Unzip the package to the specified directory

5. Tar Packaging tools

You can package a directory page to package files

Syntax: tar [-ZJXCVFPP] filename

Package: TAR-CVF Test.tar test where test is a file or directory

-c means to set up the package,-V Visualization, compressed with "-F file name", the consciousness is compressed file name filename, decompression with "-F file name."

View Package Contents: TAR-TF Test.tar

-T: View the files inside the tar package

Unpacking: TAR-XVF Test.tar

-C: Extract to the specified directory, for example: Tar-c/tmp/-xvf Test.tar

Use gzip compression while packaging: TAR-CZVF 1.tar.gz 1 where 1 can be a file or directory

Use TAR-TF to view compressed packages: TAR-TF 1.tar.gz or TAR-TF 1.tar.bz2

--exclude can exclude certain files or directories while packaging

Tar--exclude 1.txt-czvf 1.tar.gz dir/

Exclude multiple files or directories: Tar--exclude 1.txt--exclude 123/-czvf 1.tar.gz dir/
