Need help creating shell script with output that has 2014 calendar and 2 text items from a"fortune"
Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!
1. The problem statement, all variables and given/known data:
I am required to create a bash shell script with either emacs or vi. It must include the year 2014 calendar on the left side and two text items on the right side.
2. Relevant commands, code, scripts, algorithms:
the two text items are from what my professor describes as a "fortune server". I have two commands to query them. nc langley.cs.fsu.edu 19000 and " " 19001. I am also instructed that the 2014 calendar must be computed and not a fixed value of 2014. I am told to use d=`date '+%Y'` to get the current year, then told to use the Bash syntax $((++d)). I am then recommended to use pr to paste the output together with pr -t -T -m -w 140 file1 file2.
3. The attempts at a solution (include all code and scripts):
It seems to take the d=`date '+%Y'` but then when i go to Bash and type $((++d)) it says 2014:command not found.
I also don't understand how to paste the two text items into individual files in order to put them together in a single script
4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
FSU,Tallahassee, FL, USA, Langley, COP3353
Note: Without school/professor/course information, you will be banned if you post here! You must complete the entire template (not just parts of it).

calendar
calendar(1) User Commands calendar(1)
NAME
calendar - reminder service
SYNOPSIS
calendar [-]
DESCRIPTION
The calendar utility consults the file calendar in the current directory and writes lines that contain today's or tomorrow's date anywhere
in the line to standard output. Most reasonable month-day dates such as Aug. 24, august 24, 8/24, and so forth, are recognized, but not 24
August or 24/8. On Fridays and weekends "tomorrow" extends through Monday. calendar can be invoked regularly by using the crontab(1) or
at(1) commands.
When the optional argument - is present, calendar does its job for every user who has a file calendar in his or her login directory and
sends them any positive results by mail(1). Normally this is done daily by facilities in the UNIX operating system (seecron(1M)).
If the environment variable DATEMSK is set, calendar will use its value as the full path name of a template file containing format strings.
The strings consist of conversion specifications and text characters and are used to provide a richer set of allowable date formats in dif-
ferent languages by appropriate settings of the environment variable LANG or LC_TIME; see environ(5). Seestrftime(3C) for the list of
allowable conversion specifications.
EXAMPLES
Example 1: Possible contents of a template
The following example shows the possible contents of a template:
%B %eth of the year %Y
%B represents the full month name, %e the day of month and %Y the year (4 digits).
If DATEMSK is set to this template, the following calendar file would be valid:
March 7th of the year 1989 <Reminder>
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of calendar: LC_CTYPE, LC_TIME, LC_MES-
SAGES, NLSPATH, and TZ.
EXIT STATUS
0 Successful completion.
>0 An error occurred.
FILES
/etc/passwd system password file
/tmp/cal* temporary files used by calendar
/usr/lib/calprog program used to determine dates for today and tomorrow
ATTRIBUTES

NOTES
Appropriate lines beginning with white space will not be printed.
Your calendar must be public information for you to get reminder service.
calendar's extended idea of ``tomorrow'' does not account for holidays.
The - argument works only on calendar files that are local to the machine; calendar is intended not to work on calendar files that are
mounted remotely with NFS. Thus, `calendar -' should be run only on diskful machines where home directories exist; running it on a disk-
less client has no effect.
calendar is no longer in the default root crontab. Because of the network burden `calendar -' can induce, it is inadvisable in an environ-
ment running ypbind(1M) with a large passwd.byname map. If, however, the usefulness of calendar outweighs the network impact, the super-
user may run `crontab -e' to edit the root crontab. Otherwise, individual users may wish to use `crontab -e' to edit their own crontabs to
have cron invoke calendar without the - argument, piping output to mail addressed to themselves.
