Creating Perl
Perl programs are generally created with a .pl extension.
Note, if you have installed Perl somewhere other than C:\Perl,
then substitute your path for C:\Perl.
| Open MS-DOS. | |
Type cd C:\Perl\bin. |
this is where Perl is. Change path to cgi-bin? |
Type edit myprog1.pl | this should open up the text editor |
Type #!/usr/bin/perl | this is the path where Perl is to be found on the server |
Type: print "My first program!"; | this is the statement to be executed |
| Save the file | <file><save> |
| Exit | <file><exit> |
Type: perl myprog1.pl | the text 'My first program' should appear. |
On a Unix system, if you add execute permission to the file with a command such as $ chmod +x prog1.pl, the interpreter file can then be executed directly from the command line without including 'perl', for example: $ prog1.pl.
Type edit myprog2.pl | this should open up the text editor |
| Type the following: | |
$myvariable = "mine all mine"; | |
if ($myvariable eq "mine all mine") { | |
print "You're not having it!"; | |
} | |
| Save the file | <file><save> |
| Exit | <file><exit> |
Type: perl myprog2.pl | the text 'You're not having it!' should appear. |
You can also type programs in using a text editor (or a word processing program if you save as text), creating files with a .pl extension.
