sort command is case insensitive...alternatives?

[catalinnc]

hi...


on my win xp sp2 this line

Code: Select all

sort text.txt /o text.txt

makes a sorting that is case insensitive...

this is not good because i need to do a (de)dupe of the result with a case sensitive script...

content of text.txt is

Code: Select all

name1
name2
name3
NAME3
NAME2
NAME1
name3
name2
name1
NAME1
NAME2
NAME3

and the sorted text_sorted.txt is

Code: Select all

NAME1
name1
NAME1
name1
name2
NAME2
NAME2
name2
name3
NAME3
NAME3
name3

so a need a speedy alternate solution (maybe some batch with java?)


respect...

p.s. to be perfect clear i need a sorted result like

Code: Select all

name1
name1
NAME1
NAME1
name2
name2
NAME2
NAME2
name3
name3
NAME3
NAME3

or

Code: Select all

NAME1
NAME1
name1
name1
NAME2
NAME2
name2
name2
NAME3
NAME3
name3
name3

Just use the undocumented /C switch:

Code: Select all

C:\> sort /C test.txt
name1
name1
NAME1
NAME1
name2
name2
NAME2
NAME2
name3
name3
NAME3
NAME3

Great finding

The full version version of the switch is /case_sensitive

There's one more undocumented switch /u or /uni_output which will out put in unicode.

[Aacini]

Yes. Taken from sort.exe file:

Code: Select all

%s  %s case_sensitive  locale  memory  output  reverse record_maximum  temporary       uni_output  C   TEMP path   srt

Whoa! I've always wanted a case sensitive sort, and the undocumented /C option has been there all along

Great find Aacini, thanks


Another option is to use my JSORT.BAT utility. If all you need is case sensitive, then SORT /C is probably your best bet. But JSORT has a number of additional features you may be interested in.

It is a good find - but the thought that pops into my head is that the routine may not yet be robust, and is why the switch wasn't made public.

You'd think that a non-robust routine would have been removed - but we never know...

Anyone got Windows 10 so they can look at the help file to see if they added it.

It's not added in the help.
That's why I looked at sort.exe with strings.exe to see if there's something else undocumented.

Anyone want to stress test the undocumented switch? That should give us some idea if it's faulty, and if so, where.
