. If /home/jenny/draft and /home/alex/letter are links to the same file and the following sequence of events occurs, what will be the date in the opening of the letter? __________
a. Alex gives the command vim letter.
b. Jenny gives the command vim draft.
c. Jenny changes the date in the letter to January 31, 2008, writes the file, and exits from vim.
d. Alex changes the date to February 1, 2008, writes the file, and exits from vim.
To determine the date in the opening of the letter, we need to follow the sequence of events step by step.
a. Alex gives the command `vim letter`:
This command opens the file 'letter' in the vim text editor.
b. Jenny gives the command `vim draft`:
This command opens the file 'draft' in the vim text editor.
c. Jenny changes the date in the letter to January 31, 2008, writes the file, and exits from vim:
Jenny edits the file 'letter' and changes the date to January 31, 2008. Then she saves the changes and exits the vim editor.
d. Alex changes the date to February 1, 2008, writes the file, and exits from vim:
Alex opens the file 'letter' in the vim editor, changes the date to February 1, 2008, saves the changes and exits the vim editor.
Since both '/home/jenny/draft' and '/home/alex/letter' are links to the same file, any changes made to one of the files will be reflected in the other. Therefore, the final date in the opening of the letter will be February 1, 2008, as Alex made the last change to the file.
Hence, the answer is February 1, 2008.
