Hi, So you apparently want this order: `MAINUI_PF_4.0.001.10BA.8669 MAINUI_PF_4.0.001.10AU.1898 MAINUI_PF_4.0.001.10AV.7890 MAINUI_PF_4.0.001.8Q.7769` [download] Or, given that the line start is always the same, basically, you want this order: `10BA.8669 10AU.1898 10AV.7890 8Q.7769` [download] You obviously are not sorting on the last field, so that the sort key presumably boils down to: `10BA 10AU 10AV 8Q` [download] But even with this simplified view of your data to be sorted, I am at trouble figuring out the sorting rules that can lead to such an order. Can you please explain your sorting rules?	[reply] [d/l] [select]

What's the rule for sorting these values? The standard lexicographic comparison that sort uses by default produces a different order, so it's not obvious to me. Perl 6 - the future is here, just unevenly distributed	[reply]

In reading the documentation on "perldoc -f sort," especially notice the discussion of sort-comparison functions and the comparison operators (both string and numeric) that can be used within them.	[reply]


Problems? Is your data what you think it is?
