desc <<-EOT
Executes external binaries by invoking Ruby's `Kernel.exec`.
When the command is a string, it will be executed directly,
without a shell, if it follows these rules:
- no meta characters
- no shell reserved word and no special built-in
When the command is an Array of Strings, passed as `[cmdname, arg1, ...]`
it will be executed directly(the first element is taken as a command name
and the rest are passed as parameters to command with no shell expansion)
This is a safer and more predictable way to execute most commands,
but prevents the use of globbing and shell built-ins (including control
logic like "for" and "if" statements).
If the use of globbing and shell built-ins is desired, please check
the `shell` provider
