[Trisquel-users] Re : Unforeseen feature of the join command

[lcerf]

It's great that sort can be "trained" to do the same kind of multi-stage  
sorting task that appears to be built into LibreOffice Calc.

It is built in, not trained.  And GNU sort is certainly much faster than what  
LibreOffice achieves on spreadsheets, which are also limited in the number of  
rows they can have.
