It isn't obvious to me that this shouldn't be treated as homework and be required to have been posted in the Homework & Coursework Questions forum and adhere to the special rules associated with that forum. I'll leave that determination to the moderators, but I'll treat my responses as if it had been posted there.

I had never seen an if statement coded this way, but after looking at the grammar for the shell, it is a valid format. More common ways of coding if statements would be:
Code:
if [[ condition ]]
then
    true branch code
else
    false branch code
fi

or
Code:
if [[ condition ]]; then
    true branch code
else
    false branch code
fi

Although indentation is not required by the shell (and it may seem unimportant for a trivial case like this script), when the code in the true and false sections becomes more complex, indentation will make your code much easier to read. I strongly suggest that you get into the habit of always using a consistent indentation style and stick with it no matter how trivial the script is.

Other than using 2 and 4 as operands to your script, what values have you used to convince yourself that this script is working correctly? When you issue the commands:
Code:
min 8 10
    and
min 10 2

do you get what you expected?

Do you intend for your script to compare numeric values or alphanumeric string values?

IntlCalendar::getMinimalDaysInFirstWeek - Get minimal number of days the first week in a year or month can have

	Object oriented style

SYNOPSIS

       public int IntlCalendar::getMinimalDaysInFirstWeek (void  )

DESCRIPTION

	Procedural style
       int intlcal_get_minimal_days_in_first_week (IntlCalendar  $cal)

	Returns  the  smallest number of days the first week of a year or month must have in the new year or month. For instance, in the Gregorian
       calendar, if this value is 1, then the first week of the year will necessarily include January 1st, while if this value is 7, then the week
       with  January  1st  will  be the first week of the year only if the day of the week for January 1st matches the day of the week returned by
       IntlCalendar.getFirstDayOfWeek(3); otherwise it will be the previous years last week.

PARAMETERS

	      o $cal
		- The IntlCalendar resource.

RETURN VALUES

	An int representing a number of days or FALSE on failure.

EXAMPLES

       Example #1

	      IntlCalendar.getMinimalDaysInFirstWeek(3)

	      <?php
	      ini_set('date.timezone', 'UTC');
	      ini_set('intl.default_locale', 'en_US');

	      $cal = new IntlGregorianCalendar(2013, 0 /* January */, 2);
	      var_dump(IntlDateFormatter::formatObject($cal, 'cccc')); // Wednesday

	      var_dump($cal->getMinimalDaysInFirstWeek(), // 1
	      $cal->getFirstDayofWeek()); // 1 (Sunday)

	      // Week 1 of 2013
	      var_dump(IntlDateFormatter::formatObject($cal, "'Week 'w' of 'Y"));

	      $cal->setMinimalDaysInFirstWeek(4);
	      // Still Week 1 of 2013 (1st week has 5 days in the new year)
	      var_dump(IntlDateFormatter::formatObject($cal, "'Week 'w' of 'Y"));

	      $cal->setMinimalDaysInFirstWeek(6);
	      // Week 53 of 2012
	      var_dump(IntlDateFormatter::formatObject($cal, "'Week 'w' of 'Y"));

	      The above example will output:

	      string(9) "Wednesday"
	      int(1)
	      int(1)
	      string(14) "Week 1 of 2013"
	      string(14) "Week 1 of 2013"
	      string(15) "Week 53 of 2012"
