Does anyone have a trick to run sdiff to display the filenames as a header?
Hi,

Does anyone know if there is anyway to run sdiff such that it shows the name of the files as it display the results of the differences? That is, I want it to show the filenames on each column and then display the differences
I can't find any option that allows this. Maybe someone has a trick of some sort to make this happen?
If not sdiff, maybe there is another command that I can use that functions the same as sdiff but does what am after?

$ sdiff --version
