in reply to file name parsing to get the original file name

As Abigail-II suggested, use File::BaseName. However, if you are parsing HTML form input, beware: the module is not going to work regardless of the operating system of the client. Windows machines put backslashes (\) instead of slashes (/) for instance, so if you need to receive file uploaded by a Windows client and your program is on an Unix server, you'll need to do:

fileparse_set_fstype("MSWin32");

before calling the parsing function. The default FS type of the module depends on the operaing system where the script runs (it's decided upon examining the $^O variabile).

    My general rule of thumb is to use forward slashes wherever you can get away with it, and use OS-specific separators only when testing shows that they're required. Be ready to accept the OS-specific separators or the forward slashes whenever the user supplies them.

    I just tried this test on Windows with Perl 5.6.0. It shows that File::Basename accepts forward or backslashes on Windows. This is not a thorough test on all platforms and versions. 

    use File::Basename qw(basename dirname);
print basename("c:\\path\\file.txt"), $/;
print basename("c:/path/file.txt"), $/;
print dirname("c:\\path\\file.txt"), $/;
print dirname("c:/path/file.txt"), $/;
__OUTPUT__
file.txt
file.txt
c:\path
c:/path

      Output on a Linux box is... 
      c:\path\file.txt
file.txt
.
c:/path
      ...which is obviously wrong if you need to deal with the win32 input.

    Hi Michele,

    I was trying your solution since my parsing is indeed HTML form input.Tried the other solutions but can't work, it still does not recognize the '\'

    Is there anything that I should need to add before inserting the :
    fileparse_set_fstype("MSWin32");
    Because my html shows an error when I add that line.

    Thanks

      Hi all,

      Thanks for the help, for my post just now I realized that the use File::Basename shouldn't use the qw(...)

      Thanks
