// NOTE: `execve` executes a new child process, in place of the current process.
// Therefore, only the topmost example will be executed when it's not commented out.
fn main() {
// exec(["-c","find /"]) //works
exec(['-c', 'find /tmp/']) // here it works as well
// Passes only an array of args.
os.execve(os.find_abs_path_of_executable('ls')!, ['-lh', '-s'], [])!
// exec(["-c","find","/tmp/"]) // does not work I guess is normal
// Considers args that would need to be passed within quotes. E.g.: `bash -c "ls -lh"`.
os.execve(os.find_abs_path_of_executable('bash')!, ['-c', 'ls -lah -s'], [])!
// Passes an environment variable that affects the commands output.
