directories

i'm developing a script under win32 that searches through directories looking for a directory with certain characters in it's name. i'm relativley new to perl just FYI. i have 2 problems:

1- the script will work under NT but not 9x. i figure this has something to do with the file systems but i'm not exactly sure what. any ideas?

2- i need the script to look at ONLY directories, not directories and files. i assume i can do this with and if expression testing whether i could opendir it but i was just wondering if there was any easier way.

thanx and please be gentle i am but a simple newbie.

A good module that does similar things is File::Find. If you get really stuck, you might take a look at its guts. As to your two questions: There shouldn't be any file system level differences... it's more likely you've accidentally used an option which isn't supported on ActiveState's interpreter for 9x. (fork() and alarm() come to mind) The -X test will help you here. Specifically: `if (-d $filename) { print "$filename is a directory.\n"; } else { print "$filename is a file. Skipping...\n"; }` [download]	[reply] [d/l]

It should work on both. What exactly is going wrong? You can test a filehandle or a filename with the -d file test operator, which returns true if the file is a directory, false if not, and undefined if the file was not found: `for $x ("windows", "sheep", "etc") { if (-d $x) { print "Found directory: $x\n"; } }` [download]	[reply] [d/l]

Coincidentally, I asked from the wisdom of the monks on a little sub I wrote on this node. My problem was that the script was working and I didn't thing it should have. It works fine on everything I tested (Linux, NT, 95, 98 and BeOS). Just remember that on Win machines you have to indicate what HD you're running off of, ie: `my $dir = 'd:/temp';` [download] or else it will run from the place you called it... HTH... #!/home/bbq/bin/perl # Trust no1!	[reply] [d/l]
