This command is used to display the contents of a JSON file in a table format with a specific width.

Here's a breakdown of each component:

cat ${file-json}: The cat command is used to display the contents of a file. ${file-json} is a placeholder for the actual file name or path. This command reads the contents of the JSON file and passes it as input to the next command.
|: The pipe symbol (|) is used to redirect the output of the previous command (cat ${file-json}) and pass it as input to the next command.
jtbl: The jtbl command stands for "JSON Table." It is a tool used to display JSON data in a tabular format.
--cols=${width}: This is an option for the jtbl command to specify the number of columns in the table. ${width} is a placeholder for the desired width value. This option helps in formatting the output table.

Overall, the command reads the contents of the specified JSON file, passes it to the jtbl command, and formats the JSON data into a table with a specified number of columns.
