znew: Recompress a file from `.Z` to `.gz` format.

znew

$ znew ${filename1-Z}

try on your machine

The command "znew ${filename1-Z}" is written in a Bash shell scripting language syntax. Here's a breakdown of its components:

"znew": This is the name of a command or utility that is being executed. It can be a custom command or a built-in command depending on your system configuration. However, typically "znew" is used to compress a file using the compress algorithm.
"${filename1-Z}": This is a parameter or argument passed to the "znew" command. It uses the Bash shell's parameter expansion syntax. The value of the "${filename1}" can vary depending on how it is defined or assigned earlier in the script. The "-Z" is an optional flag or option that can be used with "znew" command to specify the compression algorithm to use.

If the value of the "${filename1}" parameter is provided, then the command would compress the file specified by "${filename1}" using the compress algorithm. If the value of "${filename1}" is not provided or is empty (null), then the command would compress the file named "Z" using the compress algorithm.
