Introduction of the command

The zcat command is used to display the contents of the compressed file. You can use gzip -d, gunzip, or zcat to restore the compressed file to its original format. Zcat is the same as gunzip -c.

The zcat command is used to display the contents of the compressed file without actually decompressing the file.
