Yup, that's it.

Ooops, so it does. Still a brief summary of history specific switches
would
be friendly. 'fc' in it's totality is a bit intimidating.
BTW Bart, the way I was trying to do it was educational so I don't
regret it,
and I think my question is still a useful exercise: how would we do that
if there was no easy way? Combining the words results in a 'command not
found' error, since it seems to want to believe that 'history -10 |
....' is one
command so I hafta leave the words unmagically joined yet the normal thing
seems to be to strip spaces down to a single one when making an array,
and that's a problem with the methods I was trying. I don't doubt it's
easy if you
get the incantation exactly right. It doesn't help that all this splitting
is invisible. As you pointed out:
> eval history -n $nnumber $sstring
... is a easy as pie so long as there's no need to massage the output,
but even if you do, I'm betting it's still only a couple of lines. Of
course
there's sed, but I'm banking on an internal solution.
