Write two bash shell scripts that convert between month names and numbers. Both scripts should perform error-checking on the command-line information. Ensure that: - If more or less than exactly one single command-line parameter is used, a usage error message is displayed. - If the provided input is not part of the scripts expected input, a different, specific error message should be displayed. i. The first script should be called 05-month-num. It should do the following: 1. Receive a month name as a parameter through the command line. The month name should be accepted in 2 formats: Full name (January, February, etc), or 1st 3-Letter abbreviation (Jan, Feb, Mar, Nov, Dec, etc). Be sure to note the capitalization of the input. 2. Use the bash case construct to determine and display the number of the month provided. (Jan => 1, February => 2, March => 3, Apr => 4) ii. The second script should be called 05-month-name and it should do the following: 1. Receive a number from 1-12 as a parameter through the command line. 2. Use the bash if/elif construct to display the full name of the corresponding month (1=>January, 2=>February, , 12=>December) See the following example runs for clarification on how this should work and how the output and error checking should look:

$ 05-month-num

#incorrect input (number of parameters) USAGE: 05-month-num Ex: 05-month-num Nov

$ 05-month-name

#incorrect input (number of parameters) USAGE: 05-month-name Ex: 05-month-name 11 $

05-month-name 11

#correct input The name of month 11 is November.

$ 05-month-num November

#correct input The month number for November is 11.

$ 05-month-num Nov

#correct input The month number for Nov is 11.

$ 05-month-name 42

#incorrect input (outside of range) Bad month number. must be an integer in the range 1-12.

$05-month-num april

#incorrect input (outside of range) Bad month name. must be one of the following: January, February, March, April, May, June, July, August, September, October, November, or December, or the first 3 characters of any of these names (Ex: Nov).
