Here are some tools that you can use to do the assignment:

The left hand side is generated by the program cal.
The two text items on the right hand side are from a "fortune server" that you can query at nc langley.cs.fsu.edu 19000 and at nc langley.cs.fsu.edu 19001.
To create names for temporary files, you can use the program mktemp.
To get the current year, you can use d=`date '+%Y'`; to increase the year, you can use the Bash syntax $((++d))
To paste the output together horizontally from these programs, I recommend using pr (and not paste) like pr -t -T -m -w 140 file1 file2


This is your instructor's "pseudocode" on how he wrote the script, and so what you are asked to write:
Code:
#!/bin/bash



#
# Do calendar bits
#

  # Create a temporary file for the calendar.
  # Get the year from "date".
  # Increase the year by one and then call the "cal" program with that year. Write the
  # output to the temporary calendar file.


#
# Do fortune bits
#

  # Create a temporary file to hold both of the "fortunes".
  # Collect first fortune from the fortune server at 19000 and put it in the fortune temporary file.
  # Collect second fortune from the fortune server at 19001 and append it to the fortune temporary file.


#
# Now use "pr" to push everything together (see Assignment02 guidlines), and output everything to stdout
#



#
# Remove temporary files and exit
#

exit 0

You have now ( and we also hehe...) all the information needed to do the given task, start by copying this script, it will serve you as template and documentation, try to write the calendar part, as written:
# Create a temporary file for the calendar.
# Get the year from "date".
# Increase the year by one and then call the "cal" program with that year. Write the
# output to the temporary calendar file.

Show us the result, then if OK we pass to the next part...

I have two commands to query them:
nc langley.cs.fsu.edu 19000 and " " 19001.
the output of the command is to be saved as file1 file2 for the right side output of your script...
