sEx just calls related programs, it has no compression and decompression functions, please pay attention!
There are two obvious benefits of reducing the file size of the gzip command , one is that it can reduce the storage space, and the other is that when transferring files over a network, it can reduce the transfer time. gzip 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: size of compressed file; size of uncompressed file; compression ratio; name of uncompressed file -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 for the fastest compression method (low compression ratio), -9 or -best for 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.
