First steps
Before we start on scripts written by anyone else there are a couple of things you will need to
learn how to do first. These are uploading in ASCII (text) mode and changing file permissions
with the CHMOD (CHange MODe) command.
With that in mind we need a very simple script that is known to work at Spaceports without
modifications.
Open up your text editor, ensure that word wrap is turned off, then copy and paste the
following code into a blank document:-
#!/usr/bin/perl
use CGI;
use CGI::Carp qw/fatalsToBrowser/;
# hello.cgi -- use to practice uploading and permission setting
print "Content-type: text/html\n\n";
print "<HTML>\n";
print "<HEAD><TITLE>Hello World!</TITLE></HEAD>\n";
print "<BODY>\n";
print "<CENTER><H1>Hello World!</H1></CENTER>\n";
print "</BODY>\n";
print "</HTML>\n";
Now save the file as plain text with the filename hello.cgi - you may need to put
quotes around the filename to prevent your editor adding .txt to the end of it, thus
saving as hello.cgi.txt instead. Save it as "hello.cgi" if this happens.
Check the properties of the file if you aren't sure.
Where you save this on your drive is up to you, but I suggest using the same directory structure
on your hard drive as you intend to use with the online version. Put it in a directory called
scripts or something to keep it separate. Any practice scripts you create can then
be kept away from those you download.
As a beginner, it is a good idea to get into the habit of keeping each script in its own
directory if it has multiple files. If you save multiple scripts to the same directory you
will most likely overwrite existing files with the same name. For basic individual scripts,
you can put them together though.
