PDF FILES

First use acroread to open the file. Then use acroread's "print" menu.

JPG AND GIF FILES

First use Firefox to open the file. Then use Firefox's "print" menu.

For text files, you can first convert them to ps files before you print them. You can use Unix command "enscript" to do this. Enscript converts text files to PostScript and spools gen- erated PostScript output to the specified printer or leaves it to file. If no input files are given, enscript processes standard input. Enscript can be extended to handle dif- ferent output media and it has many options which can be used to customize printouts (Use command "man enscript" to find more information).

SYNTAX:

enscript [options] filename

OPTION EXAMPLES:

         -1, -2, --columns=num
                 Specify how many columns each page have.  With  long
                 option  --columns=num  you  can  specify more than 2
                 columns per page.

         -a pages, --pages=pages
                 Specify which pages are printed.  Page specification
                 pages can be given in following formats:

                 start-end
                         print pages from start to end

                 -end    print pages from 0 to end

                 start-  print pages from start to end

                 page    print page page

                 odd     print odd pages

                 even    print even pages

         -A align, --file-align=align
                 Align separate input files to even align page count.
                 This  is  handy  for  two-side  and  2-up  printings
                 (--file-align=2).

         -b header, --header=header

EXAMPLE

          enscript foo.txt
                  Print file foo.txt to the default printer.

          enscript -2 foo.txt
                  Print file foo.txt to two columns.

          enscript -2r foo.txt
                  Print file to  two  columns  and  rotate  output  90
                  degrees (landscape).

          enscript -G2rE -U2 foo.c
                  gaudy header,  two columns,  landscape,  
                  code highlighting, 2-up printing.

Most printers will print on both sides of the paper by default -- to make the print-out single-sided, try adding s at the end of the printer's name. 

Bogofiltler needs train/retrain often to make it works 100%
See this URL for how it works
http://www.bogofilter.org/

We use the term "ham "for email you want, "spam" for email you don't want.  We also assume you save your ham/spam and others email in mail/ folder.  See Notes below of you only have Mail (uppercase) folder.

1. Login to  SUN Unix server only.
2. ssh your_login@stat.ubc.ca  (Be.stat.ubc.ca)

I have have a copy of spam folder for you to start training bogofilter manually.

          bogofilter -sM < /usr/local/data/etc/bogofilter/spam
 

Second step, you need "ham" email to train bogofilter. 
You can use any saved email (good known emails) as ham.
          bogofilter -nM <  mail/ham  
or 
          bogofilter -nM < mail/tha

NOTES: If you only see Mail (Uppercase) folder, do this 
          ln -s Mail mail
        
Bogofiler will store your database in your home dir ~/.bogofilter/wordlist.db

Edit your .procmail file using vi or emacs or pico by typing 
         vi ~/.procmailrc

1. Add to content below:
   :0fw

   | /usr/local/bin/bogofilter -u -e -p

   :0e

   { EXITCODE=75 HOST }

   :0:

   * ^X-Bogosity: Spam, tests=bogofilter

   mail/Bspam

   :0:

   * ^X-Bogosity: Unsure, tests=bogofilter

   mail/Bunsure

   # Used during vacation: forwards to vacation, then makes a cc for # myself

   # Unhash 2 lines below to turn on your vacation

   #:0 c

   #|/usr/bin/vacation -t1d $LOGNAME

   Notes:  "Bunsure" and  "Bspam" are two "spam" and "not sure" spam files that bogofilter saved for you in the mail folder.  You need to check them often to make sure you don't have false positive or false negative. You need to sort  "Bunsure" and  "Bspam" into real "ham" and "spam" and "re-train "your filter to update your bogofitler database (wordlist.db)
                        

To enable the filter type

Sending large attachments via Email is an inefficient and wasteful way of disseminating information to a large group of people, as one copy is made for each recipient. It taxes the network, mail servers, disk storage of both the sender and especially the recipients, and sometimes the recipient's patience if they use a dial-up modem for their internet connection.

The typical scenario is that someone will broadcast information (and sometimes committing the double sin of formatting it in a proprietary format) to a mailing list that may contain hundreds, or even thousands, of recipients. A copy is then made for each individual recipient. So, for example, if 4 megabyte attachment is sent to a department mailing list with 250 people, an aggregate of 1 gigabyte of mail storage is used by this one message.

Some Email accounts (e.g. Hotmail, Yahoo) have size quotas, and sending large attachments to them will either fill up or severely reduce the available space for new mail.

It is also typical that not all of the recipients need or want the attachment, yet these recipients have already expended the considerable computing overhead to receive, scan or filter for spam and viruses, and store the large attachment.

A far better strategy is to post the information or file onto a web site (or FTP site if you have access to one), then Email out a short message that describes the contents and refers interested parties to the URL. This will allow people who want the data to pull the data off the web site at their leisure, and those who don't can delete the message without having incurred the overhead of receiving all the data in the first place.

Using this method with the above scenario, a 1K blurb instead of a 4Mb attachment will mean a three-orders of magnitude (1/4000th) reduction in computing resources.
