[oh-my-zsh] For safety, we will not load completions from these directories until
|
|
[oh-my-zsh] you fix their permissions and ownership and restart zsh.
|
|
[oh-my-zsh] See the above list for directories with group or other writability.
|
|
|
|
[oh-my-zsh] To fix your permissions you can do so by disabling
|
|
[oh-my-zsh] the write permission of "group" and "others" and making sure that the
|
|
[oh-my-zsh] owner of these directories is either root or your current user.
|
|
[oh-my-zsh] The following command may help:
|
|
[oh-my-zsh] compaudit | xargs chmod g-w,o-w
|
|
|
|
[oh-my-zsh] If the above didn't help or you want to skip the verification of
|
|
[oh-my-zsh] insecure directories you can set the variable ZSH_DISABLE_COMPFIX to
|
|
[oh-my-zsh] "true" before oh-my-zsh is sourced in your zshrc file.
