jot(1) fulfills the same fuction as seq(1) - the former predates (first appeared in 4.2BSD) the latter, hence it can be mostly (only?) found on the *BSDs so there was never need to re-implement seq(1) there, while the latter is in GNU land and Plan 9 who haven’t adopted jot(1).
I’m sure there are reasons this would be useful, I’m just failing to see them. What problem does this solve?
I can’t immediately come up with a reason, but I’m sure there’s one … somewhere haha.
I can only come up with “testing tool”. It would be nice if this was mentioned somewhere in the manual, though.
