I have a long string of characters ( 40,000 chars)

Is there a simple way to do this in Perl? unpack()
doesn't seem to be the right solution; there are no
terminations for the strings I'm after.
Maybe that works for you?
my $string = 'string_of_40k_chars';
my @strings = $string =~ /.{6,6}/g;
my $remainder = substr($string, -1, length($string)%6);
Have I actually found something that is easier in C
than in Perl?
I couldn't tell.

You mean /.{6}/ instead of /.{6,6}/, I think. The latter will indeed
work, though.
I forgot that RE are greedy, thus /.{6}/ make the remainder line
superfluous, thanks.
If you really wanna use that regex thing, use:
my $alphabet = join( , A..Z );
my @chunks = ( $alphabet =~ /.{1,6}/g );
#my @chunks = unpack( (A6)*, $alphabet );
print join( , , @chunks ), \n;
But really, that unpack() trick is the way to go.
xoa
learning new stuff all the time, thanks again. Is unpack the more
efficient (faster, or less memory requiring) way to do this?

CPAN broken in Panther
Are there others having problems with CPAN in 10.3. ? None of the file transfer methods seems to work and everything times out on more than 10 different ftp archives. I already followed the instructions from one BSD mailing list: http://news.gw.com/comp.unix.bsd.openbsd.misc/37614 but it only skips the initial retrieval errors, and just copying all perl modules in the .cpan directory outside of CPAN just to install them from the cpan shell doesn't seem to be the solution. I know that lynx, wget, ftp etc are working outside of cpan I would be grateful for your advise or pointers to the archives (where I must have missed it then). thanks/h -- 1GHz TiBook 1GB - Superdrive MacOsX 10.3 aim: hannes92122 www: http://users.sdsc.edu/~hannes

Re: File write/read problem

It would also explain (I thingk) why I can't change the permissions of any of those directories with an ftp client. So if I change the ownership of the cgi-bin (and all the folders associated with the server) to www:www, then I should be able to write to the file. How is that accomplished? Thanks for your help, May I suggest that think of the security implications by making cgi-bin work writeable. It only has to be world executeable NOT more. If you want to write to a file write to a directory outside of cgi-bin in mac osx you might want to use /Users/shared/. If you still want change ownership issue the command 'man chown' in the terminal (without the quotes), for changing file permissions use 'man chmod'. Please Do inform yourself before you change ownership and permissions - you can screw yourself big time. JM2C/h

I've been coding for a short time (a year or so) and love it. I've been using other hosts for my scripts, and am now setting up my OSX server. I've run into a snag. I can't figure it out. When I try to read (or write, for that matter) to a file nothing happens. Below is an example script. If the file is there, nothing. If the files is not there, nothing. I get the initial print statement about the file contents, but that's it. Is this a permissions problem? I've checked the permissions of the folder and it's 775, everything looks good.

Since you get the initial statement - e.g. Part of your program are actually run through the interpreter I assume that you've taken care of the path to perl and also made sure you got Unix and NOT Mac line breaks. You probably intend to run this as a cgi script - thus how did you actually run the script? /h

I corresponded a bit with the author and he is aware that it works fine on 10.1 (I had it working) and it does not on 10.2. The module hasn't changed since last October or so. He has no Apple hardware to chase down the solution and it works everywhere else. He said if I, or anyone else I suppose, got it to install with some technique he would appreciate the info. I just recently found a solution that worked great for me on Mac OSX 10.2.4 (and 10.2.4 Server). Mount http://packages.opendarwinports.org in your finder install perl5.8 and all the libraries that you want from there. All the installs go in /opt/local and are very unlikely to interfere with anything you've installed already. The relink /usr/bin/perl to /opt/local/bin/perl and make sure you are running the new perl (which perl should now point to /opt/local/bin/perl). I also choose to put /opt/local/bin on position one in my path. Then run cpan -MCPAN -e shell and install all the modules you want, most of them work right out of the box and XML::LibXML and XML::LibXSLT did not pose any problem. Let me know if I was not detailed enough. HTH/h

I've only used ssh in the Terminal. -Tim Grant DBA, Knowledge Express If walk through means explain what I mean here it goes: Most of the files that I edit on my Powerbook reside on a Sun Host befind a firewall that does not allow insecure traffic (telnet ftp, etc.). To access them via BBEdit's FTP open remote function I establish an SSH tunnel that allows me to pipe the FTP through the firewall like: ssh -L 2025:remote.server.edu:21 remote.server.edu I can then establish an FTP connection in BBEdit using the local port (of the tunnel)127.0.0.1:2025 The question is in the context of the Shebang line but also of remote CVS check in and out. Someone posted that BBEdit would now read #! /which/perl/shall/I/use And checks the syntax against that Perl installation. I was wondering whether BBEdit would be so smart to see that a file actually resides on a remote server and would then test the perl script syntax against the remote Perl installation. The CVS question was already asked in a different mail, but basically can I use the CVS running on the remote server from within BBEdit? I hope I explained that ok? Best/h
