filter for up-arrow in terminal

[SternData]

A long time ago, in an operating system far, far away I used a tool
called PCED.  It had one really nice feature:  If I had typed a command like

copy a b

it saved it, just like bash does.  But when I typed

copy

and pressed up-arrow, it would filter the history entries and show only
those that started with "copy".

I'm already using autojump for the cd command. Is there something to
provide this filter on using up-arrow to scroll through past commands?

Yes: in bash, just start typing what you're looking for after ctrl-r.
Ctrl-r is bound by default to incremental search backwards.

You can have the same behavior with page-up. This feature must be
configured in /etc/inputrc:

# alternate mappings for "page up" and "page down" to search the history
"\e[5~": history-search-backward
"\e[6~": history-search-forward

which is (AFAIK) default in fedora.

Best regards
