what do you want to sort.
when the filenames are random, then you can not generate those filenames using this
secondly, when you are using the paste command, there is no need to sort as the list could be required in any order depending on the the user.

Hi, Unix Gurus,
In our existing file, there is a script like

My question is what's "${1:-0}" mean? I know it defines a variable but I don't know what's (1:-0) mean?
:wall:

Perl::Critic::Policy::Subroutines::ProhibitReturnSort(3)User Contributed Perl DocumentatioPerl::Critic::Policy::Subroutines::ProhibitReturnSort(3)
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.
