Hi
I'm trying to check to see if a paticular file exist on the machine,
i'm unable to check for files insides directories which have space in
between their names, If i run the script from the command prompt they
seem to run fine, but when i try to open the script on a browser, it
is not able to even open the directory, i get a Invalid Argument
Error,This does not happen for directories which do not have a space
in their name.Any help is greatly appreciated

perldoc -q 500

I bet you're not using CGI.pm, and you're not decoding URI-encoded
entities properly. After you've followed all the directions in the
FAQ I just referred you to, try creating a small CGI program, using
CGI.pm, that just prints out "It exists", or "It doesn't exist" when
you pass a filename as a parameter. It shouldn't take more than 10
lines. Doing this will probably help you debug your problem.

How are you passing the directory name in to the CGI script? If you
are passing it through the GET method (i.e, the directory name
is part of the URL) then make sure that you replace each space
with the character triple %20 -- .e.g,

http://www.yahoo.com/~vijaysenthilv/...n/checkfile/hi there #wrong
http://www.yahoo.com/~vijaysenthilv/...ile/hi%20there #better

Show us your code that is trying to check to see if a paticular file
exist on the machine, and we will help you fix it.

perldoc -q browser

My CGI script runs from the command line but not the browser. (500
Server Error)

Any code is greatly appreciated.

See "perldoc -f -e"

Then chances are your problem is _not_ a Perl problem. Please see
"perldoc -q 500"

> but when i try to open the script on a browser,

How do you "open a script on a browser"?

Well, quite impoossible to do without seeing your code (or actually a
minimal example that exposes the problem).

Hi
I'm sorry i should have posted the code
__________________________________________________
require "cgi-lib.pl";
print "Content-type: text/html\n\n";



if (!(-e 'J:\DWGS\parking\LOT-10.dwg')) {
print "Not working----"
}

else {
print "working---";
}



if (!(-e 'J:\DWGS\Project Archive\911-001-1922-A-002-AB.pdf')) {
print "Not working----"
}

else {
print "working---";
}

The above code prints working and working when i run it from the DOS
promt but prints working and Not working when i open it in a browser,
i Did try using the %20 and forward slash format but that didnt help
either


Thanks

I suspect your question is a variation of this faq:

My CGI script runs from the command line but not the browser.

That is, I think you have a CGI question rather than a Perl question.

I am not going to mention strict, warnings and CGI.pm now,
but I might next time.

the %20 does not apply in your case.

does the problem go away if you rename away the space ?
does the first filepath fail if you rename a space into it?

maybe it is a permission problem. the user executing the script
as cgi is not the same as the one in the shell. and their environments
differ as well.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Please tell me this is something *you* wrote and not the old Perl4 CGI
library ......

If it's the latter, *please* consider using the CGI module .....

I get a invalid Argument error when i try to opendir command on
directories with space in their file name.I guess its a CGI error than
something to deal with perl, i'll try searching CGI sites to see if i
can come up with a fix
Thanks
