test: test [expr]
    Evaluate conditional expression.
    Exits with a status of 0 (true) or 1 (false) depending on
    the evaluation of EXPR.  Expressions may be unary or binary.  Unary
    expressions are often used to examine the status of a file.  There
    are string operators and numeric comparison operators as well.
    The behavior of test depends on the number of arguments.  Read the
    bash manual page for the complete specification.
    File operators:
      -a FILE        True if file exists.
...
      arg1 OP arg2   Arithmetic tests.  OP is one of -eq, -ne,
                     -lt, -le, -gt, or -ge.
    Arithmetic binary operators return true if ARG1 is equal, not-equal,
    less-than, less-than-or-equal, greater-than, or greater-than-or-equal
    than ARG2.
    See the bash manual page bash(1) for the handling of parameters (i.e.
    missing parameters).
    Exit Status:
    Returns success if EXPR evaluates to true; fails if EXPR evaluates to
    false or an invalid argument is given.
