delete history commands

To delete command from current shell history and $HISTFILE use redodel command then chose command and press Del or F8.

Using Del/F8 when using redo bind key (Esc/ or CtlR) 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 :

  shopt -s histappend cmdlist
  PROMPT_COMMAND='history -a'
  

limitations

• zsh on ubuntu 22 : in vi mode, to have Esc/ correctly binded, you need to put in ~/.zshenv:

  skip_global_compinit=1
