lz4: Decompress a file.
$ lz4 -d ${file-lz4}
try on your machine
The given command "lz4 -d ${file-lz4}" is used to decompress a file that has been compressed using the lz4 compression algorithm.
Let's break it down:
- "lz4" is the command-line tool used for working with lz4 compression.
- "-d" is an option that stands for "decompress" or "uncompress." It instructs the lz4 tool to decompress the file.
- "${file-lz4}" is a placeholder for the name or path of the lz4 compressed file that you want to decompress. It indicates that you should replace "${file-lz4}" with the actual name or path of the file you want to decompress.
So, when you execute this command by replacing "${file-lz4}" with the name or path of an lz4 compressed file, it will decompress that file and restore it to its original form.
