I'm running similar commands on (e.g.) a set of files. As an example, let's say I'm doing something like this (this isn't what I'm doing, it's just an example):
> cat path/to/dir/file01.txt
[file contents]
> another-command path/to/dir/file01.txt
[more output]
> cat path2/to/dir/file02.txt
[file contents, from which I can tell I should do something different]
> different-command path2/to/dir/file02.txt
[yet more output]
> cat path3/to/dir/file03.txt
[file contents]
> another-command path3/to/dir/file03.txt
[output]
etc.
It would be convenient if, after using the ↑ key to return to a previous command, I could overwrite non-duplicated text ― like the file name, or a common part of the path — rather than having to delete it and retype it.
Is there a way to do this?

Bash has that but it isn't bound to any key by default.
Add the line
to your
$HOME/.inputrc
or/etc/inputrc
to use Ctrl+o to toggle between insert mode and override mode.See the
READLINE
section in the Bash manpage for more.
