xxd Command Not Found

If you see the xxd command not found while running some script or apps on a Linux / Unix system that means the xxd command is not installed.

Basically, the xxd command is a Unix command that can be used to display or edit binary files in hexadecimal format. It can also be used to convert between hexadecimal and binary formats.

The xxd command is a utility that comes with the Vim text editor, and it is often used in Linux or Unix-based systems. The xxd command creates a hex dump of a given file or standard input. It can also convert a hex dump back to its original binary form.

When you use xxd, it displays the hexadecimal representation of the data, along with the printable ASCII characters (if any are present). This can be useful when you’re working with binary files, and you need to see the data in a human-readable form.

If the xxd command is not found on your system then the command is not present.
