Package: cereal
Version: 0.21-1
Severity: normal
Hi,
if udev's SYMLINK function is used to have static device names for
USB-to-serial adaptors, cerealadmin's method to detect the group
needed is flawed:
SGROUP=$(ls -l "$TTY" | awk '{ print $4 }')
will get the symlink's group, which is root.
A better approach would be to dereference the symlink before obtaining
the group.
SGROUP=$(stat --dereference --printf="%G\n" $4)
Alternatively, ls's -H switch can be used.
Greetings
Marc
