I encountered a weird issue with globbing in perl not returning all files, while I was testing out a script for recursive dir-processing on my Synology NAS.
Basically it didn't show (/match?) all the files in a specific directory. If I move the file to a different directory or even rename it, it STILL doesn't show, as if something is wrong with the file.
If I copy the file to a new file, neigher of the files are showing.
I can pipe more data into the file and touch it - It doesn't make a difference until I create a new file (e.g. pipe new data into it, thus overwriting it):
This has caused some serious headscratching... The closest thing I got while googling, was someone claiming that glob is heavily buggy.
I'm open to alternatives, but I hope they are not too different, since I've already made a pretty huge script based on the browse-function. I guess I could simply call the 'ls' command itself, but it would be nice to have something more perl-native.
Since I can't post URL's yet, I'll paste the browse script here (for good measure):
Hello All,

I am completely new to perl programming. My father is helping me learn said programming language. However, I am stuck on one of the assignments he has given me, and I can't find very much help with it via google, either because I have a tiny attention span, or because I can be very very dense.

Hi,
Can someone please clarify how we are able to use both IO and GLOB symbols of a package variable interchangeably?
Please consider the following code:
open(FH,"myfile") || die "Unable to open file myfile:$@";
my $glob_var = *main::FH{GLOB};
my $io_var = *main::FH{IO};
print $glob_var... (0 Replies)
