In order to cope with having to use Windows at work I run Cygwin. My shell of choice is zsh. For whatever reason the Cygwin package of zsh installs with a series of directories that the zsh completion system deems to be insecure and it makes sure you know this. Each time a new shell is opened (in my case through a Windows native rxvt terminal) I would receive the following warning:
|
|
|
|
Ignore insecure directories and continue [ny]?
|
|
|
|
Pressing 'y' becomes a bit tedious after a while so I decided to track down these insecure directories and fix them.

Running compaudit revealed the following:
|
|
|
|
% compaudit
|
|
There are insecure directories:
|
|
/usr/share/zsh/site-functions
|
|
/usr/share/zsh/4.3.4/functions
|
|
/usr/share/zsh
|
|
/usr/share/zsh/4.3.4
|
|
|
|
Examining the permissions on these directories showed they were all group writable.
|
|
|
|
% ls -ld /usr/share/zsh/site-functions
|
|
drwxrwx---+ 2 wmoore mkgroup-l-d 0 Sep 4 10:54 /usr/share/zsh/site-functions
|
|
|
|
Stripping them of the group write permission fixed the problem and made starting a new shell a little more pleasant.
|
|
|
|
% chmod g-w /usr/share/zsh/site-functions /usr/share/zsh/4.3.4/functions /usr/share/zsh /usr/share/zsh/4.3.4
|
|
% compaudit
|
|
%
|
|
|
|
**Update:** _kylexlau_ provides this one line solution for correcting to permissions on each of the directories that compaudit returns:
|
|
|
|
compaudit | xargs chmod g-w
|
