You don't even need to know that 'From:' is 5 characters, if you use

open() creates the filehandle FILE which is associated with the contents of
the file "file.txt".

You are using a file glob to get a list of file names which is the same as
doing:

Hi:
I have a question about replacing $ sign when it is
before a digit. For example:
$str = "$1.12";
I want to extact the dollar amount 1.12 from $str.
If I do this:
$str =~ s/\$//;
$str then become .12. The "$1" in "$1.12" is
interpreted first before substitution is applied. How
do I prevent
Hi all, I need to get the modified date of a file on the server, the code I
have returns "Thu Jan 1 01:00:00 1970" even if I modify the file, so the
modified date doesn't change. I am using the following code:
open(HANDLE, $FILE);
my $date = localtime( (stat HANDLE)[9] );

I am not sure whether anyone can help here.
I am building a gui for amongst other things ffmpeg and I seem to have
hit an issue with ffmpeg.
What I am trying to do is to run a ffmpeg command and then pass that
to a TextView in the main window.
ie:
$fh-> "ffmpeg -i somefile opts outfile"

Thanks for reply. The question is easily solvable if
it is in the same file as the perl script. You can use
single quotes or backslash to modify the string.
But as I stated in the message, the "$1.12" was in a
text file along with other things, say you have a
sentence like this in a file: Apple $

That sounds as if the stat() failed.
open(HANDLE, $FILE);
Try this:
open(FILE,"f:/file.txt") || print("open() failed as file did not exist.\n");
while (){
print $_;
}

Hi
open F
It would probably be better to let the OS tell you why the open failed
by using the $! or $^E variables when you're checking why the open()
failed. It could be failing because the file was not found, or the file
could be locked somehow, or the user might not have read permissions on
the file.

You could cycle through the array and use split() to split each element
by whitespace and then append the result to the @new_array array using
push();

Do you mean to break the elements on whitespace?
my @new_array = map { split } @a

Both line codes work perfectly:

The second statement will work perfectly if every element has only one
space character separating its components and has no lead

Oh, yes, a special case. I have long ago abandoned special cases since

Hi,
I have a script that sorts the IDs with numerials first followed by alphas.
Everything works ok except that there are some IDs in the input file that are
duplicates. How can I "omit" and duplicate IDs
from the output file?
