I was using my $tmp = glob("file20240101.*") to find the full filename regardless of the extension(I knew there was only one of each file), when I found glob was alternating between working and failing
Rendering it as my ($tmp) = glob("file20240101.*") fixed the problem, but I'm wondering why, If it was going to go wrong I'd have thought treating glob's list in a scalar context would return the number of elements in the list
#!/usr/bin/perl
use warnings;
use strict;
for (1..4) {
my $tmp = glob($0);
print "$_ $tmp\n";
}
print "###\n";
for (1..4) {
my ($tmp) = glob($0);
print "$_ $tmp\n";
}
Output:
1 glob.pl
Use of uninitialized value $tmp in concatenation (.) or string at glob.pl line 7.

3 glob.pl
