Subject: Re: Unix to dos; dos to unix...
Hi There,
Just a small addition on the remarks :
I don't know if you realy want this to automate, but vi can do it as well.
Just type :
:1,$s/[Ctrl + v] [Ctrl + m]//g
The [Ctrl + v] makes you able to type in an escape character.
Most of all the [Ctrl + m] (^M) is bothering you.
:) I know, I know. It's beginners@perl and not beginners@unix.
Just want to help.
Good Luck !!

There is a utility out there that will convert unix-style end-of-lines (LF)
to dos-style (CR/LF)...
Just for giggles, I'm trying to write a perl script to do this...
Here's what I've tried...
while (INFILE) {
$line = $_;
$line=~tr/\012/\015\012/;
print OUTFILE ($line\n);
}
The problem is that the output, when viewed with notepad, contains
inappropriate line breaks...
The same input file, when converted using the unix utility unix2dos,
converts properly. This leads me to believe that I'm missing something
obvious here
I'm not asking for the answer per se, but perhaps a pointer?

RE: perlcc the system cannot find the file specified. ??
I did ...I went to \perl\bin and found perlcc.bat - I then copied my .pl program (lamore.pl) there and typed: perlcc -o z.exe lamore.pl It started running and invoked Perl twice and then coughed up that message. I browsed perlcc.bat and did not find the message in there so it must be coming from perl.exe but no clue on which file perl.exe wants.

Hi Jonathan,
Very interesting reply and it opened my eyes(!)scary stuff.
Kindly explain a bit before I write some PERL/CGI code
and have a user fill in a field that I do a regexp
on and wipe out my web hosting site!!
You should be very, very scared indeed. If you are doing
CGI you do need to take a lot more care. Taint mode is helpful
when you wish to strengthen your code. I'd read the relevent
security chapters a few times over, it is quite enlightening.
perldoc perlsec
Also, do get your code checked out by peers... it's amazing
what others can spot that you didn't know. If you don't have
anyone then email it to the list (if small or complex) or myself
(if big). I quite enjoy pointing out subtle problems/issues when
reviewing code ;)
I write because I tried what you did (changing the rm etc!!) and
it doesn't work, i.e. I tried this for $two on perl v5.6.0
on my PC platform and it does not create junk.txt as I think
it should. I also do not find the ? command in my perl books.
perldoc perlre
$two=?{system 'echo hello world junk.txt'}
Okay, I've just tested this one. I haven't been telling
the whole truth it seems! This *WILL ONLY* be executed in a
use re 'eval' scope - which gives you some security from it. The other
problem kind I showed still causes it's grief without this. Just
remember that someday, someone *could* put that statement in.
You need to place () around the ?{} block, by the way.
(I am somewhat of a newbie, using perl every day since mid
September 2001 to process and compare large text files and fields
therein).
I was a paid summer student starting just two months
earlier, for a period of 12 weeks... however, I had/have plenty of time
to dig into the interesting things.

how to tell if hash value is null vs missing
Consider this perl stub:
$value=$myhash{$mykey};
If the value in the hash at $mykey is , then $value becomes and
if $mykey is not a valid key, then $value still becomes
How do I differentiate between the two?
Please email me (email address below) if you know the answer.
