I uninstalled Homebrew, manually removed the /usr/local contents.
The following possible Homebrew files were not deleted:
/usr/local/.DS_Store
/usr/local/bin/
/usr/local/etc/
/usr/local/include/
/usr/local/lib/
/usr/local/libexec/
/usr/local/share/
/usr/local/texlive/
/usr/local/var/
You may consider to remove them by yourself.
You may want to restore /usr/local's original permissions
sudo chmod 0755 /usr/local
sudo chgrp wheel /usr/local
I want to know what the suggested commands do.

When you perform the
chmod 755 filename
command you allow everyone to read and execute the file, and the file owner is allowed to write to the file as well. You may need this for Perl and other scripts that should to be run via a webserver. If you apply 755 to a directory, it means that everyone can go to it and get its file listing.When you run
chgrp group-name filename
command you change the group of each filename to group-name.Running both commands using
sudo
prefix let you be sure that the changes takes effect, because your run it asroot
that is the user with most permissions on every single unix like machine.You can type
man chmod
,man chgrp
orman sudo
for more info and options.
