Hi Dima, all,
I've attached a patch which aims to implement 'echo' and 'uniq' as aliases to
'cut' and 'unique' respectively. Anyone who is interested should be able to try
it out with `git apply /path/to/patch'.
I'm not quite sure whether to merge it. If you look in the tests, you'll see that when
datamash tries to do a "reverse lookup" of what command was used, it can't see
the alias. It instead sees the original command. (Basically because of what comes first
in a particular array, iiuc.)
Perhaps that's reasonable behavior for what is clearly flagged as just an
alias. Furthermore, to try to fix it would require some refactoring of the
field_operation structures, I think. If this is necessary, it should wait until
after v1.8 has been released.
Feedback welcome. I'll merge it tomorrow (i.e. Saturday morning Australia time)
if no significant objections arise.
