    Dang!
    Have you ever used the Linux terminal?
    Use the same conventions for path naming

    What exactly are you trying to do lol.

    It should be something like cd <folder>

    try this

    Code:
    #!/usr/bin/perl -w
    
    $dirname = "/tmp";
    
    opendir ( DIR, $dirname ) || die "Error in opening dir $dirname\n";
    while( ($filename = readdir(DIR)))
    {
         print("$filename\n");
    }
    closedir(DIR);

    which platform are you writing this for? Windows, Mac, Solaris, AIX, HP-UX, Linux?
    Are you sure you have a tmp directory?

    Here is complete code i am using:-
    Error:- No such file or directory

    Dir:-CUBAS_ComStack_COMMON(placed in same directory as script)

    Code:
    #!/usr/bin/perl
    
        use strict;
        use warnings;
    
        my $dir = '/CUBAS_ComStack_COMMON';
    
        opendir(DIR, $dir) or die $!;
    
        while (my $file = readdir(DIR)) {
    
            # Use a regular expression to ignore files beginning with a period
            next if ($file =~ m/^\./);
    
    	print "$file\n";
    
        }
    
        closedir(DIR);
        exit 0;

    Try removing the '/' from the dir name!

    Your code is correct. Check the perms on the directory.

    Okay... this really has nothing to do with C. You probably want `ls -R /tmp` (for recursive) or `tree /tmp`. Both can be found in the manual.

    true, about the c part, but for perl look up function

    finddepth

    are you trying to create the Unix find command?

    for c programming try ftw function.

    yeah right zacs!
    at least move to general discussions.

    but this can surely be done using C:
    Code:
    char cmd[512];
    sprintf(cmd, "ls -R &#37;s", dirName);
    system(cmd);
    Edit: I forgot to add my dreaded laugh!
    MuwahahahahahhaHaHahahaahhaaahahahahha

    Har har, you funny man

    If you wanted to do it in C, opendir/readdir() would be your best bet. Rather trivial if you ask me
