So, several months ago I started experimenting with the fish shell, and I made the decision that I like it. In fact so much that it will become my shell of the day - at least in the interactive shell used from within Konsole (KDE ftw) - I will not change the EOS default shell, this will still be bash, due to sanity and reasons and sane reasons. Changing the shell in Konsole is quite easy sad and done, but I will lose my precious bash history. How do I keep it?
fish imports the bash history when you first run it.
Have you tried renaming the fish history file and seeing if that causes it to re-import the bash history?
