| Subject: | Error while using the module with |
Issue in : File-Util-3.27
I am using the File::util module for listing the directories.
The script runs as a non root user, so when this lists the directory
/etc/,it leads to a fatal error. The part of the error is as follows.
"The system returned this error:
»Permission denied«"
So i have used --fatals-as-status option in new() to proceed with the
script after returning undef.
But in this case I get the following error.
Can't use string ("0") as an ARRAY ref while "strict refs" in use at
/usr/local/lib/perl5/site_perl/5.10.0/File/Util.pm line 274.
In the module at line 274 the result of list_dir is being pushed into an
array "dirs".
The list_dir on occurence of an error returns undef which is being push
into the "dirs" array without handling the undef condition.This is the
cause for the above error.
