cause I think the -k is interpreted as specifying the input twice. ow would I change this so that its as equivalent as possible but runs on windows? Thanks

And what does the documentation say?

I'm on windows, I have two sort.exe files on my system, one came with perl, the other is gnu sort

They have different syntaxs

I don't use the windows version much, but to avoid breaking some batch files and stuff that rely on it, I also named the gnu version gsort.exe

You can distinguish between the two 

$ sort /? |head
SORT [/R] [/+n] [/M kilobytes] [/L locale] [/REC recordbytes]
  [[drive1:][path1]filename1] [/T [drive2:][path2]]
  [/O [drive3:][path3]filename3]
  /+n                         Specifies the character number, n, to
                              begin each comparison.  /+3 indicates th
+at
                              each comparison should begin at the 3rd
                              character in each line.  Lines with fewe
+r
                              than n characters collate before other l
+ines.
                              By default comparisons start at the firs
+t
                              character in each line.

$ gsort /?
gsort: open failed: /?: Invalid argument
