Hi Everyone,
I'm having a problem with extracting certain strings
within a line. I tried several ways, but not very
inefficient. Can somebody help me with it? thanks a
lot.
The line might be one of the following:

Hi everybody,
Can we use substr function for a string like:
$file = atom 12 N VAL A 1 12.435 13.66 34.6 32.1 32 a N
can the decimal numbers be extracted using
$x= substr($file, offset, length)
(the exact field lenghts of each field are known).
Thanks in advance..

push @col, "" if $line =~ /\t$/;
which should REALLY have been written as
my @col = split /\t/, $line, -1;

Ok,
the best way (in my opinion), would be, assuming 's' and 'e' are the
start/end special characters:
$string =~ s/^.*?(s.*e).*$/$1/;

thanks a lot. But there is one problem - this is my
fault. The KEY1, KEY2 don't exactly look like this.
There are six KEYS. Three are related to KEYS, but the
rest of them are A_BEG A_END, B_OPTIONS, and I need to
extract information between them. I used one variable
$op=KEY1|KEY2|KEY3|A_BEG|A_

After second thought
This line:
my @y = grep { $_ if ($_ =~ /\d+/)} @list;
could be simplified with this:
my @y = grep { /\d+/ } split(/\s+/,$file);
Since grep { $_ if /\d+/ } wouldn't match on 0, but grep /\d+/ would.
I'm still wondering how can I do that with "unpack" :-(

I have an array of strings whose members consist of a number followed by
a comma followed by a text string
e.g.
1,fresh
2,testurl
I want to sort by descending numerical order according to the number
part so I made this sort subroutine
sub by_counter_field {
my($a, $b) = @_;
$a =~ s/^(.*?),
ack cat climbed the green tree";
$substring = substr( $s, 1, 15); # this will return "The black cat c".
How can I have this return the whole word climbed rather than the c (i.e. I
need to get "The black cat climbed")? I need to get the remaining characters
from the l
offset I used, so I should be fine I think.

How can I have this return the whole word climbed rather than the c (i.e. I
need to get "The black cat climbed")? I need to get

I don't think this would work if the value given in the match string (15 as per
above eg.) is greater than the character count of the particular string. Right?

No, it will fail if $str is less than 15 characters. Try:
uot;The black cat climbed the green tree";
$substring = substr( $s, 1, 15); # this will return "The black cat c".
No it will not. It will return "he black cat cl" because in perl
offsets start at 0 and not 1:
$ perl -le'
my $s = "The black cat climbed
the next white space or end of a phrase.
Any other way to overcome this limitation? How can I use regex here?
$ perl -le'
my $s = "The black cat climbed the green tree";
my $length = length $s;
my ( $substring ) = $s =~ / \A ( .{15,$length}? \b ) /x;
print $substring;

Yeah, this would do. I talked about the scenario where you didn't put "{0,15}",
but just "{15}". In that case, it wouldn't work if the value given in the
match string (15 as per above eg.) is greater than the character count of the
particular string

That would have to be
my ($rtioverview) = $string =~ /(.{0,99})\S\b/;
to avoid terminating at the start of a non-space sequence.
