Running a docker alpine container, my PS1 is:

PS1="u@h:w$ "

So when logging into the container, you get

root@worker:/$

So if I type in something like

root@worker:/$ cd /tmp/dir/path

And then do a reverse-i-search for tmp/di

The prompt looks like this for each character along the way:

(reverse-i-search)`t': cd /tmp/dir/path
(reverse-i-search)`tm: cd /tmp/dir/path
(reverse-i-search)`tmp cd /tmp/dir/path
(reverse-i-search)`tmp/cd /tmp/dir/path
(reverse-i-search)`tmp/dd /tmp/dir/path
(reverse-i-search)`tmp/di /tmp/dir/path

So now that I've typed tmp/di, if I hit the end key the prompt looks like this:

root@worker:/$tmp/dir/path

Worth noting that if I hit enter it performs the correct command, and if I scroll back through the history, it shows the correct command, so it's clearly just something to do with the presentation.

I'm wondering if this is a problem with my PS1 or if I've done something else wrong.

Thank you!

Edit:

Here is the entire .bashrc
