The command "hexyl ${filename}" is used to execute the program called "hexyl" with a specific file as input.
Basically, "hexyl" is a command-line program that caes the content of a file (in hexadecimal format) and displays it in a visually appealing way. It shows the hexadecimal values of each byte in the file, as well as the corresponding ASCII characters. This can be useful for inspecting binary files, understanding their structure, and uncovering hidden patterns or information.
The "${filename}" part of the command is a placeholder for the actual file name you want to analyze. You need to replace it with the path and name of the file you want to examine in order for the command to work properly. For example, if you want to analyze a file called "example.bin" located in your current directory, you would run the command as "hexyl example.bin".
