UBB.Developers Forums Community Development Programming PHP and Server-side Scripting Some questions...

I was wondering...


What does



mean in Perl? I see it in if statements that opena some sort of file. And I have seen some other letters like that I think. Could you explain to me all the letters and what they do?

if (-e 'foo.pl') {

means "if the file foo.pl exists, then...."

You can get a list and explanation by typing

perldoc -f "-x"

at a command line

--mark

like your new/old quote Mark

George

George

George of the jungle...

... strong as he can beeee!

So how exactly do I get it to work? I tried put it in a cgi file like


perldoc -f "-x"


but it didn't work. Just a server error. Is there a different way to do this?

you'll use that command locally :rolleyes: to get an explanation of the command.

open command prompt `terminal in linux or command in windows` and type;

perldoc -f -x

also, there must be html perl documents in your system that are installed with perl... you can read them...

common ones are:

-e (file exists)

-x (file is executeable)

-r (file can be read)

-w (file is writeable)

-d (is a directory)

Thanks jordo. I am somewhat new to this so I don't understand some stuff.

I have a question.

if (-e '/ubb/ubbcgi/ultimatebb.cgi') {

I want it to find a file thats is on the same domain but a subdomain like board.stonecrick.com ... how do I get this to work. I tried doing it with the folder name on FTP and the full address because the file that is calling this is located at http://www.stonecrick.com/file.pl


That's not the real file but ya know what I mean.

if the file and script are on the same account or server;

if (-e '/ubb/ubbcgi/ultimatebb.cgi') {
#do something
} else {
#do something
}

will work... if they are in different machines or accounts, the program can not find the file...

Ok, Thanks.
