gzip command

Reducing file size has two obvious benefits, one is to reduce storage space, and the other is to transfer files over the network, you can reduce the transmission time. Gzip is a regular use of Linux in the file compression and decompression of the command, both convenient and useful.

Syntax: gzip [option] Compress (uncompress) file name 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 uncompressed. -T test to check that the compressed file is complete. -V displays filename and compression ratio for each compressed and decompressed file. -num adjusts the speed of the 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 default value for the system is 6. Instruction instance:

Gzip *% compresses 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 *% details the information for each compressed file in Example 1 and does not understand the pressure. GZIP usr.tar% Compressed tar backup file Usr.tar, at which time the compressed file extension is. tar.gz.
