gzip command

There are two obvious benefits of reducing file size, one is to reduce storage space, and the other is to reduce transmission time when transferring files over the network. Gzip is a frequently used Linux system command to compress and decompress files, which is both convenient and useful.

Syntax: gzip [option] File name for compression (decompression)

The options for this command have the following meanings:

-C writes the output to the standard output and retains the original file. -D Unzip the compressed file. -L Displays the following fields for each compressed file: The size of the compressed file, the size of the uncompressed file, the     compression ratio, the name of the uncompressed file-R recursively finds the specified directory and compresses all of its files or is decompressed. -T test to check that the compressed file is complete. -V for each compression and decompression file, display the filename and compression ratio. -num adjusts the speed of compression with the specified number num,-1 or--fast represents the fastest compression method (low compression ratio), 9 or--best represents the slowest compression method (high compression ratio). The system default value is 6.

instruction Example:

Gzip *% compress each file in the current directory into a. gz file. GZIP-DV *% extracts each compressed file in the current directory and lists detailed information. Gzip-l *% Detail shows the information of each compressed file in Example 1, and does not understand the pressure. Gzip usr.tar% compress the tar backup file Usr.tar, at which time the compressed file has a. tar.gz extension.
