Hello,
I am not shure if I post this question in the right mailing list, but
let's try.. ;-)

Hi,
I am new to the list and newbie in perl.
I have a big flat file(100G). The file was supposed to be in a single line
but many of records(as it has ^M). There are also ^@ and tabs in between.
I want to first replace the control characters and tabs with space.
I tried this s/[[:cntrl:]\t]/ /g.

Hi All,

$R->send(qq`x <- c(1,2,3) \n shapiro.test (x)`);
to
$R->send(qq`x <- c(1,2,3) \n out <- shapiro.test (x) \n print (out)`);
Which then gives you the result as it should.

I have a field that a user must enter that must be in a specific
format. For example:
F8_A01F0123
The pertinent parts are F8, A, 01, F, 0123, while the underscore is

I have come up with the following regular expression to match this
pattern.

Hello everyone
I want to list all the Perl modules installed on my system. The script
below does it well.
Unfortunately, it displays the name of each installed Perl module twice.
How can I get rid of them?
Lastly, if you have any suggestion about improving this script, it would
be very nice.
