Re: chmod 660 on /dev/pass*

Okay,

>Well, make it three columns: device owner:gid permission.

It's late, but here's a first shot.


(1) The /etc/devperms.local config file:
---------------------------------------------

#################
# devperms.local test file
#################


# bacula-sd needs access to /dev/pass?, so grant rw permissions to
group.
pass*   root:operator   660     # This space for rent

# Test entry: keep MAKEDEV's ownership and permissions
nsa0    root:operator   660

# Fridge access
fridge  heinz:ketchup   644





(2) What could be appended to MAKEDEV:
------------------------------------------------

DEVPERM_FILE="/etc/devperms.local"

# No local device permissions file, so go home
[ -f $DEVPERM_FILE ] || exit

# Read stuff from file
cat $DEVPERM_FILE |
while read LINE
do

        # Skip empty lines and comments
        [ `echo $LINE | grep -c ^$` -eq 0 ] || continue
        [ `echo $LINE | grep -c ^#` -eq 0 ] || continue

        # Split current line into fields
        set - `echo $LINE`

        # Ignore lines with less than three fields
        [ $# -ge 3 ] || continue

        # Need a separator ':' in field #2 (owner:group)
        [ `echo $2 | grep -c :` -eq 1 ] || continue

        # Check if last char of field No.1 is an asterisk
        DEVICE=`echo $1 | cut -d\* -f1`
        FAMILY=`echo $1 | cut -d\* -f2`

        # Just do it
        if [ -z "$FAMILY" ]
        then

                # Set owner, group and permissions for entire device
family
                ls -1 /dev/${DEVICE}* |
                while read ENTRY
                do

                        echo "Family: $ENTRY --> chown $2 --> chmod
$3"
                        #chown $2 $ENTRY
                        #chmod $3 $ENTRY

                done

        else

                # Set owner, group and permissions for a single device
                echo "Single: $DEVICE --> chown $2 --> chmod $3"
                #chown $2 $DEVICE
                #chmod $3 $DEVICE

        fi

done



Could be beautified, but according to local time here, it's okay...and
works. (After getting rid of line wraps :)
