Hi Guys,
the following piece of code doesnt seem to work
my $folder= $hash{working_directory};
chdir("$folder") or die "can't change dir $folder" ;
I printed out the output and checked if the the variable $folder was
being loaded and it was being loaded correctly.
while this works if I put in the absolute path.
chdir("/test/rep") or die "can't change dir /test/rep" ;
hmmmm any thoughts.
cheers,
pop.

Why are you quoting that variable?

Perl is your friend. Let it help by telling what went wrong:
or die "can't change dir $folder: $!";

hmmmm. Are you sure that the working directory of your script is what
you think it is? Quick and dirty check: print `pwd`;

Hi David,
Still learning, I put in the $! and it gave me this error
"can't change dir /test/rep/
No such file or directory at custom.pl line 156."
The working dir of the script is /users/XXX/perlscripts/ and I am
trying to access a folder at the home level /test/rep to run a command
in that folder.

thnx. Thats what I did. I was a bit posessed by the idea of a preforking
server and lost the focus somehow.
I now have a forking server thats running very nice and consuming very
little memory ;)

I guess you can start off with going through the following parts of
Perl
File access, File parsing and Regex. This should show give you point
knowledge on how to parse files and search for specific sites.

Subject: transfering a string from client to server without deadlock?
Message-Id: <446afd4e$0$581$79720d31@newsreader.inode.at>
I use Net::Daemon for a very simple server-client-szenario
client is sending a string to the server and the server is processing
the string and returning a answerstring to the client and the client is
terminating.
Problem: the string is very long and can contain virtually any character
(its the output of freeze() from the Storable-Module which serializes
even complex hashes)
So how does the Server know when the Client has finished sending its string?
I tried several attempts that all works, but I'm sure they will fail on
certain data:
* the client sends the length of the string first, so the server knows
how much data it needs to wait for. (this will sure fail when using
utf8-encoded data and client/server will be on different machines with
different perls)
* I use a very complex "EOF"-pattern like \n\0\0\0\0\n and pray to my
gods that this pattern will never be part of the string.
I am sure that there is a much better/simple/prooved solution to this
problem that must be a standard-problem.
thnx,
peter
