I know I can use an ls -l junk1 command to get a listing of all files in the directory junk1, but I was wondering how I'd go about going through the files in junk1 in a for-in loop and issuing the ls -l command on them one by one.

Perl::Critic::Policy::Subroutines::ProhibitReturnSort(3pUser Contributed Perl DocumentatPerl::Critic::Policy::Subroutines::ProhibitReturnSort(3pm)NAME
Perl::Critic::Policy::Subroutines::ProhibitReturnSort - Behavior of "sort" is not defined if called in scalar context.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
The behavior of the builtin "sort" function is not defined if called in scalar context. So if you write a subroutine that directly
"return"s the result of a "sort" operation, then you code will behave unpredictably if someone calls your subroutine in a scalar context.
This Policy emits a violation if the "return" keyword is directly followed by the "sort" function. To safely return a sorted list of
values from a subroutine, you should assign the sorted values to a temporary variable first. For example:
sub frobulate {
return sort @list; # not ok!
@sorted_list = sort @list;
return @sort # ok
}
KNOWN BUGS
This Policy is not sensitive to the "wantarray" function. So the following code would generate a false violation:
sub frobulate {
if (wantarray) {
return sort @list;
}
else{
return join @list;
}
}
CONFIGURATION
This Policy is not configurable except for the standard options.
CREDITS
This Policy was suggested by Ulrich Wisser and the <http://iis.se> team.
