Hope you are familiar with the programming language by now.
If some of you still dunno how to execute a simple perl script,
please remember this.
$ perl foo.pl
$ cat foo.pl
for(1..1000) {
print; print "\n";
}
You can easily accomplish many difficult tasks in text processing
with perl even without using any regular expressions.
You can easily convert all input into upper case:
$
$ cat i.pl
while(<>) {
print uc;
}
Perl's documentation is written in plain old documentation format (POD)
which can be converted into pdf, text and of course the nroff man format.
You can find all these converters:
$ pod2
pod2html pod2latex pod2man pod2test pod2text pod2usage
Perl's POD documentation can either be invoked using:
$perldoc foo.pl
if the file contains the documentation inline or even if the file that contains
pod is in the standard search location.
$perldoc perltoc
will tell you all the topics covered by perl's installed documentation.
It is huge, massive and no amount of reading will help you learn perl
unless you
really get down to trying perl and running it.
Perl cannot be run interactively like Python. You have to run it one
script at a time.
All perl functions are written in the perlfunc man page.
$perldoc perlfunc
But it is useless. Instead you say
$perldoc -f split
or
$ perldoc -f join
or some such thing.
Some of the perl functions you can learn today are
1)map
2) tr
3) substr
4) push
5) shift
6) pop
7) keys
8) values
9) pack
10) ord
Just google and try out the examples.
