Have you ever hit alt + backspace while in a zsh session, intending to delete just the last part of a path, or a word, or an identifier, but ended up deleting far more than that?
This is probably because you are using the default value for $WORDCHARS.
The default value for $WORDCHARS is
*?_-.[]~=/&;!#$%^(){}<>
i.e. pretty much everything and the kitchen sink. Usually, therefore, you will want to remove characters which you don’t want to be considered parts of words
You can delete a word in a terminal? Is this zsh specific or is there a bash equivalent?
Terminal user for 20 years, never heard of this.
Alt+Backspace works in bash too, and should work in any other command-line program that reads input using readline.
