delete history commands
To delete command from current shell history and $HISTFILE use redodel command then chose command and press <kbd>Del</kbd> or <kbd>F8</kbd>.
Using <kbd>Del</kbd>/<kbd>F8</kbd> when using redo bind key (<kbd>Esc</kbd>+<kbd>/</kbd> or <kbd>Ctl</kbd>+<kbd>R</kbd>) will not remove command from current shell history (line editing limitation), but the $HISTFILE will be purged from the command.
When deleting history in $HISTFILE using redo bind key, set the following options to ensure the history is not written later in $HISTFILE by shell.
-
zsh options to set :
setopt appendhistory setopt incappendhistory -
bash options to set :
