Problem with regular expressions!!!
As u probably have guessed some part of my code is not working properly and
i don't understand why!!
This is the code.
#
$file_completename =~ /(.*?)\.(.*)/;
if ($2 eq $extension]) {
#DO SOMETHING!!!
}
#
As u see, i'm trying to separate the complete name of a file in two parts,
the filename ($1) and the extension($2)... then i check to see whatever a
extension is of some kind and if it is, i do something.
However this doesn't work. Because in $2, perl adds a . before the
extension.
4 example: if file_completename equal to myfile.jpeg, then $2 equials to
.jpeg, but it should be jpeg.
What am i doing wrong?
Thank u very much,

You should use the split function here:
my @file = split /\./, $file_completename;
$file[1] will contain the extension, without the leading .

It looks odd to me b/c * and ? are both quantifiers which usually
triggers an error when you try to run it. See if this works for you:

It's cool to know that it worked fine in your computer, i guess i did it

Just to make sure this doesn't slip through, in his case $2 refers to
the second match in the previous regular expression so he was using it
correctly. This is a variable automagically set by Perl during the
regular expression operation he had based on the grouping ().
So for example:
if ($string =~ /^(\d*)65(\d*)/) {
within this block $1 will be set to anything that matched before the
'65' and $2 will be set to anything matched after the '65'. And so on...
}
Because of these types of special cases you shouldn't use variable names
such as $1, $2, $3, $a, $b (see 'sort'), etc.
You will also find in the case of the numbers, that the variable is a
global so 'my'ing will fail, and on top of that you will most likely get
a bareword found where operator expected syntax error (though there may
be ways around that). So your suggestion not to use that type of
variable name is correct, for your own variables, but there are times
when you will want to use Perl's builtin variables, which was the case
here...

I think the problem may be in the value of $file_completename...
[..]
I think the OP may have a problem with what is really
in that $file_completename that was not planned for.
To test this I put together:
sub split_me {
my ($file_completename, $extension) = @_;
$file_completename =~ /(.*?)\.([^\.]*)$/;
if ($2 $2 eq $extension )
{
print we match $extension for $file_completename\n;
}
else
{
print FAIL to match $extension for $file_completename;
print - . $2 if ( $2 ) ;
print \n;
}
} # end of split_me
split_me(bob.txt , txt);
split_me(bob.html , txt);
split_me(bob.txt.html , txt);
split_me(bob.txt.html.txt , txt);
split_me(/some/path.here/bob.txt , txt);
the first two cases work as expected and the next three
will help show a part of the problem
we match txt for bob.txt
FAIL to match txt for bob.html - html
FAIL to match txt for bob.txt.html - txt.html
FAIL to match txt for bob.txt.html.txt - txt.html.txt
FAIL to match txt for /some/path.here/bob.txt - here/bob.txt
if one changes the RegEx to say
$file_completename =~ /(.*?)\.([^\.]*)$/;
then the output looks like:
we match txt for bob.txt
FAIL to match txt for bob.html - html
FAIL to match txt for bob.txt.html - html
we match txt for bob.txt.html.txt
we match txt for /some/path.here/bob.txt
the regex looks at ONLY the last stuff after a '.'
note also that if we had
split_me(bob , txt);
that this would fail, and without the test to see
that $2 existed we would get a warning about attempting
to compare it to $extension.

searching for a string

I was trying the following code :

$string = the lucky coin;
if ($string =~ m/(\b)the(\s)(\b)lucky(\s)(\b)coin(\b)$/) {
print Yup,exists.\n;
} else {
print nope \n;
}
}
But the results are not as expected.
I was thinking of the following :
search for the then ignore blank spaces,tabs,newlines and look
for lucky .If found then also print the next word which will be
lucky .Is there no pipes in perl ?
