I am trying to completely disable the zsh completion system. I removed the following from my `.zshrc`: autoload -Uz compinit compinit Still it is giving some suggestions. I used: zstyle ':completion:*' use-compctl false Still it is giving some suggestions. For example, % ls ls lsblk lshw lslocks lsmod ..... I guess I am looking for something like zstyle ':completion:*' use-compsys false So, what can I do to completely disable zsh completion system. *Thanks ,Ahmad Ismail*
