Perl: Basics
A Perl program is an ASCII text file. To run it, you load it into the
Perl interpreter. Thus if your program were name "testprog" you would
run it via the command perl testprog.
Under Unix, you can can have this happen
automatically by making
#!/usr/local/bin/perl
the first line of your program, and changing the attributes the
program file to include 'executable'.
Thus, a typical 'hello world' program looks like:
#!/usr/local/bin/perl
print "hello world \n";
Things to note:
- Perl statments all terminate with a ;
- You have to explicitly tell
print to print the
linefeed "\n"
