eval [ arg ... ]
       Read the arguments as input to the shell and execute the result\xe2\x80\x90
       ing command(s) in the current shell process.  The return  status
       is the same as if the commands had been executed directly by the
       shell; if there are no args or they contain  no  commands  (i.e.
       are an empty string or whitespace) the return status is zero.
