pax:tldr:89549

The command "pax -f ${archive-tar}" is used to access or extract the contents of a tar archive file specified by the variable ${archive-tar}.

Here's a breakdown of the command:

• "pax" is the command-line utility for handling archive files in various formats, including tar.
• "-f" is an option flag for pax that specifies the archive file to be operated on.
• "${archive-tar}" is a variable placeholder that should be substituted with the actual name or path of the tar archive file you want to work with.

So, when you run the command and replace ${archive-tar} with the appropriate value, pax will read the specified tar archive and perform actions like extracting, listing, or updating the contents of the archive.
