gzip

Gzip is a command line tool used for file compression and decompression in Unix-like operating systems. It is short for GNU zip.

1. Gzip helps reduce the size of files, which is particularly useful for storage and transfer efficiency.
2. It uses the Deflate algorithm to compress files.
3. Compressed files typically bear the ".gz" extension.
4. Gzip is commonly used in conjunction with tar to create compressed archives (.tar.gz or .tgz).
5. When compressing a file, gzip replaces the original file with the compressed version.
6. It can compress individual files or multiple files in a directory.
7. The command to compress a file using gzip is simply "gzip" followed by the file name.
8. Decompressing a file is done with the command "gunzip" followed by the compressed file name.
9. Gzip also supports some additional options, such as "-r" for recursively compressing directories and "-d" for directly decompressing files.
10. Gzip works efficiently on a single file, but does not support compressing multiple files simultaneously like the zip command.
