"foo" is not recognized as an internal or external command, operable program or batch file. Some early Unix shells produced the equally cryptic " foo: no such file or directory " again accurately describing what is wrong but confusing users.

Some commands, such as echo, false, kill, printf, test or true, depending on your system and on your locally installed version of bash, can refer to either a shell built-in or a system binary executable file. When one of these command name collisions occurs, bash will by default execute a given command line using the shell built-in. Specifying ...

l – Command-line arguments are passed individually (a list) to the function. p – Uses the PATH environment variable to find the file named in the file argument to be executed. v – Command-line arguments are passed to the function as an array (vector) of pointers. path
