Substituting ls with ls -FGP system-wide?

[ph0enix]

I would like to substitute the ls command with 'ls -FGP' for all users and shells. How should I go about doing that?

Thanks!

/etc/profile

alias ls='ls -FGP'

Inform your users, especially the ones working with symlinks ..

That only works for bourne-type shells. Use /etc/csh.cshrc for csh. Note that aliases can be overridden by users. If that's a concern, then move /bin/ls to /libexec/ls and make /bin/ls a shell script:

#!/bin/sh
exec /libexec/ls -FGP $*

Which you will have to do with after each installworld. Probably easier to maintain a local patch to ls, that will set -FGP, like:

--- ls.c        2008-04-03 19:57:46.000000000 -0800
+++ /tmp/ls.c   2009-03-07 07:38:08.000000000 -0900
