Printing on the Meteorology Maproom (3008) Laser Printer
Students should now be able to print on the the meteorology maproom laser
printer (3008 Agronomy Hall). Doing so is very similar to printing on the
Durham printers described below. The general form of the command is:
lpr -G subsidy_username -Pah3008-lj4250 filename
For example:
lpr -G subsidy_flory -Pah3008-lj4250 my_program.f90
This command should be entered from a terminal window on any of the classroom
or maproom machines.
This will create a printout of the designated file and a cover sheet with your
ISU NetID identifying the owner of the printout. Printing will cost $0.03 per
sheet and you will not be charged for the cover sheet. Once your
subsidy runs out, charges will appear on your Ubill. If you want the
charges to go directly to your Ubill rather than using your subsidy account,
you can type:
lpr -G ubill_username -Pah3008-lj4250 filename
For example:
lpr -G ubill_flory -Pah3008-lj4250 my_program.f90
Creating a file of your output
To create a file of your required test runs, you can use the command 'script'
to capture everything that goes to standard output. To use the command,
type:
script
at the command prompt. Once done, everything that goes to the screen will be
captured in a file called 'typescript'. When you are done capturing your
output, enter:
CNTL-D
You should now be able to list the contents of the file 'typescript' using
'more' or 'less'.
If you would like to tell the program what to name the output file, use the
-a flag. For example:
script -a hw1_flory.out
will capture everthing sent to the screen to a file called 'hw1_flory.out'
when 'CNTL-D' is entered.
Submitting your homework for grading
To turn in your homework for grading, follow the instructions below:
- Create a copy of your finished program called hw#_YOURLASTNAME.f90. For
example, for homework #1, I would create hw1_FLORY.f90.
- Create a copy of your output called hw#_YOURLASTNAME.out. For example,
for homework #1, I would create hw1_FLORY.out.
- Send both of these files as an attachment to: mteor227@iastate.edu
Printing from the Meteorology computer system
Following the instructions here will cause the files to print at Durham
and then appear in a mailbox (bin) there. I also give an alternative method
in case the primary one does not work for you.
Primary method To do this, first determine a bin number where
you want the file to go.
Durham bin numbers are between 200 - 475. You choose a number, but it
is best to avoid commonly used simple numbers like 200, 300, 400,
222,333,444. You will also need to specify that you want to use your
ISU subsidied account for the print charges. To print your files, enter
:
lpr -B ### -G subsidy_username filename
For example:
lpr -B 153 -G subsidy_flory my_program.f90
where ### is the bin number you choose and the option "-B" uses an
uppercase letter. The printouts will go that
bin in the large computer lab on the first floor of Durham (Durham 139).
Mailing files from the Meteorology computer system
An alternative to method of printing your file would be to mail your
program to your account and open it on a machine which has access to a
local printer. The method you are probably most comfortable with using is
WebMail. Since most of you are more familiar with WebMail than I, I won't
describe its use here. Give it a try. There really isn't a good alternative
using Linux unless you want to learn a new mail handler.
