Dear All,
I have sort of questions, would you please give me some hint, even refering me to a
perldoc would be nice too.
1. When I open a text file with *lines, however, I just want to read the first line,
would this be a good idea ?
open (FILE, "textfile.txt"); $firstline = <FILE>; close (FILE);
would this process run till EOF, or terminated after read $firstline ?
2. I am using Win32 system , would you tell when is \n apprear and when is \r\n
apprear ?
What about this when dealing with binary files ?
3. Is this different for this 2 scripts ?
version 1 : sub any { for (@data) { my ($a, $b) = split (/=/, $_) } return 1 }
version 2 : sub any { my $a, $b ; for (@data) { ($a, $b, $c) = split (/=/, $_) }
return 1 }
4. Is that reading binary data faster then reading text file ?
5. How can I write multiple line if remark like /* and */ pairs, instead of using #
at every line ?
6. Is that any syntax for local call about 'use' and 'require', so as something like
'not require', 'not use' expressions ?
7. Would you give me some short examples for //e, and //g ? I am confused for their
usuage.
8. Any modules can help to check connecting threats for a certain page ? or if I run
$alive = `ping $ip` a good idea ?
9. Any modules can help to read and write the ID3vX for mp3 files ?
Any ideas and respond will be very very helpful..... Really urgent for a project
design and development.....
Thank you very much =)
Connie
