$ whence "${command}"

try on your machine

The command whence "${command}" is typically used in Unix-like systems, such as Linux or macOS, to determine the path of an executable file associated with a specified command.

Here's a breakdown of the command:

whence: It is a command in Unix-like systems that is used to locate the binary file associated with a command or find the location of shell built-in commands.
"${command}": The variable command holds the name of the command you want to find the path for. By enclosing it within double quotes "${}", any potential special characters or spaces in the command name would be preserved during the variable expansion.

Therefore, when you run the command whence "${command}", it will search for the executable file associated with the specified command and display the path to that file if it is found.

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.
