The gzip command is a command that is often used in Linux systems to compress and decompress files, which is convenient and easy to use.
Syntax: gzip [options] Compressed (decompressed) filenames The meanings of the options of this command are as follows:
-c Write output to standard output and keep the original file.
-d Decompress the compressed file.
-l For each compressed file, display the following fields: compressed file size; uncompressed file size; compression ratio; uncompressed file name
-r Recursively find the specified directory and compress or decompress all files in it.
-t Test to check if the compressed file is complete.
-v For each compressed and decompressed file, display the file name and compression ratio.
-num Adjust the speed of compression with the specified number num, -1 or --fast means the fastest compression method (low compression ratio), -9 or --best means the slowest compression method (high compression ratio). The system default value is 6.
Command example:
gzip *% compresses each file in the current directory into a .gz file.
gzip -dv *% Extract each compressed file in the current directory and list detailed information.
gzip -l *% Displays detailed information about each compressed file in Example 1, but does not decompress it.
gzip usr.tar% Compresses the tar backup file usr.tar, and the extension of the compressed file is .tar.gz.
