To get matching entries, you can write
printf "%s\n" $history | grep foo
and to get the indices
printf "%s\n" $history | grep -n foo | cut -f 1 -d :
True, it can be shorter if there was a special-purpose string matcher,
but don't you think this would be bloat?
It would be neater if the commands operated with objects instead of
strings, and iPython does something like that.
