The command "zmore ${filename-txt-gz}" is used to view the contents of a compressed text file (.txt.gz) in the terminal.

Here's how it works:

• "${filename-txt-gz}" is the variable placeholder that should be replaced with the actual filename you want to view.
• The command starts with "zmore" which is a Linux command for viewing compressed files, specifically compressed text files.
• The "zmore" command is followed by the filename, enclosed in ${}, which tells the command to replace the variable with the actual filename.
• The filename should have the extension ".txt.gz" indicating that it is a compressed text file (compressed using gzip).

By running this command, the compressed text file specified by the filename will be decompressed in memory and displayed in the terminal, allowing you to read its contents without having to extract it.
