try on your machine

This command performs a simple data transformation using two command-line tools, "cat" and "jtbl".

Let's break it down:

"cat" is a command used to concatenate and display the contents of files. In this command, it is used with a variable called "${file-json}". The variable is expected to contain the name or path of a JSON file.
"${file-json}" is a placeholder for the actual name or path of the JSON file. It is usually provided by the user or retrieved from another part of a script.
"|" (pipe) is a command-line feature that allows the output of one command to be used as input for another command. In this case, it takes the output of the "cat" command and pipes it to the "jtbl" command.
"jtbl" is a command-line tool used for formatting and displaying tabular data. It takes JSON data as input and produces a human-readable table representation. The "-n" option tells the "jtbl" command to include numbering in the columns of the output.

So, overall, this command takes the JSON data from the specified file, passes it through "cat" to read its contents, and then pipes the output to "jtbl" to display the data in tabular form with numbered columns.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
