z: Restrict matches to subdirectories of the current directory.
$ z -c ${foo}
try on your machine
The command "z -c ${foo}" can be broken down into two parts:
-
"z": It represents a command or utility that is being executed. It could be a standalone program or a shell built-in command.
-
"-c ${foo}": It is an option to the command "z". The "-c" flag usually stands for "execute commands contained in the following argument". "${foo}" is a variable reference enclosed in curly braces. It means that the value assigned to the variable "foo" will be used in place of "${foo}".
So, when you run the command "z -c ${foo}", it executes the command "z" with the option "-c" and replaces "${foo}" with the value stored in the variable "foo". The specific behavior of the command depends on the program or command "z" and how it handles the "-c" option.

never run a command you are not sure if it is safe.
