This is another excellent candidate for an extended vi editing mode.

The shell command line editing description says only: "Repeat the most recent non-motion command, even if it was executed on an earlier command line."

The shell description says: "Repeat the most recent f, F, t, or T command." with no mention of the remembered search character. > (I'm using http://pubs.opengroup.org/onlinepubs/9699919799/utilities/vi.html > as > my reference) I use the shell command line editing description in http://pubs.opengroup.org/onlinepubs/9699919799/utilities/sh.html#tag_20_117_13_03 Chet -- ``The lyf so short, the craft so long to lerne.'' - Chaucer ``Ars longa, vita brevis'' - Hippocrates Chet Ramey, UTech, CWRU [email protected] http://tiswww.cwru.edu/~chet/ _______________________________________________ Bug-readline mailing list [email protected] https://lists.gnu.org/mailman/listinfo/bug-readline
