Thanks for the review. Like this?
#!/bin/bash
# Fix a problem introduced by older versions of setup.exe
# Directories with 1777 permissions were erroneously created
# with 777 inheritable default permissions. This is a security
# problem for non-Cygwin apps using these folders. This is
# especially tragic in case of /tmp.
GUARDFILE="/etc/.1777fix"
DIRLIST="/home /tmp /usr/tmp /var/log /var/run"
if [ ! -f "${GUARDFILE}" ]
then
cnt=0
success=0
for file in ${DIRLIST}
do
# We test if the default group or other permissions are rwx.
# If so, it's dangerous and highly likely that these are still
# the permissions set by setup.exe
case $(getfacl "${file}") in
*default:group::rwx* | *default:other:rwx* )
cnt=$(($cnt + 1))
setfacl -m d:g::r-x,d:o:r-x "${file}" 2>/dev/null \
&& success=$(($success + 1))
;;
esac
done
# If no file needed treatment, or if all setfacl calls succeeded,
# create the guard file.
[ $cnt -eq $success ] && touch "${GUARDFILE}"
fi
