I'm using Fish with vim mode and something seems to have gone wrong, where the prompt displays the currently mode of vim (here [I] for insert) your terminal seems to interpret this as a command, so nothing works unless I delete the [I] at the start of the line. [I] [I]ls fish: Unknown command: '[I]ls'
