argument is a number, print the calendar for the entire year.

Write a spell_check program to check your spellings. The script

requires two filename arguments: the 1st file contains your list

of correctly spelled words, and the second file is the file that

is to be checked. Prints out the incorrect spellings from the

file to be checked. e.g.

$ spell memo

Blankenship

Klimowski

targat

hte

Note: the memo file includes the words you want to check their

spellings. You can use spell utility to detect those words

not included in the standard dictionary. Refers to the

spell utility for more informations. ($man spell)

$cat word_list

Blankenship

Klimowski

Note: the above file (word_list) is the list of correct words

you want to add to the standard dictionary.

$ spell_check word_list memo

targat

hte
