Windows executable have directory permission in udev automount

Hi! I've used the arch wiki to set automount
https://wiki.archlinux.org/index.php/Ud … n-mounting
My rule looks like that:

KERNEL!="sd[a-z]*", GOTO="media_by_label_auto_mount_end"
ACTION=="add", PROGRAM!="/sbin/blkid %N", GOTO="media_by_label_auto_mount_end"

# Individua l'etichetta
PROGRAM=="/sbin/blkid -o value -s LABEL %N", ENV{dir_name}="%c"
# utilizza basename per to gestire etichette come ../mnt/foo
PROGRAM=="/usr/bin/basename '%E{dir_name}'", ENV{dir_name}="%c"
ENV{dir_name}=="", ENV{dir_name}="usbhd-%k"

ACTION=="add", ENV{dir_name}!="", RUN+="/bin/su tomk -c '/usr/bin/pmount -A -u 177 --dmask 066 %N %E{dir_name}'" 
ACTION=="remove", ENV{dir_name}!="", RUN+="/bin/su tomk -c '/usr/bin/pumount /media/%E{dir_name}'"
LABEL="media_by_label_auto_mount_end"

Directory are marked "executable" of course, all files but .exe are not. How can I change .exe permissions?

Re: Windows executable have directory permission in udev automount

I actually have not configured UDev like you have mentioned.. But at times I have seen cases where files in windows partitions do not have any execute permissions.. It was always because the corresponding fstab entry had "noexec" flag.. I even got the problem a couple of times when "noexec" flag was not specified.. It always worked for me when I removed the "noexec" flag (if present) and added the "exec" flag to the fs entry in /etc/fstab
Maybe you can try the same

Scuse me for the delay,
I have no entry in /etc/fstab and I've tried to toggle the flag -e in the rule without results

ACTION=="add", ENV{dir_name}!="", RUN+="/bin/su tomk -c '/usr/bin/pmount -A -u 177 --dmask 066 %N %E{dir_name}'" 

ACTION=="add", ENV{dir_name}!="", RUN+="/bin/su tomk -c '/usr/bin/pmount -A -e -u 177 --dmask 066 %N %E{dir_name}'"

Re: Windows executable have directory permission in udev automount

Paraphrasing man pmount (which I know you read):

One of the pmount options is --exec.  You will note from the documentation that the default is noexec (recheck line 47 of the man output)

Edit: Okay, I see you are using the -e option.  Sorry.  Never-the-less, look further down the documentation and look at umask vs dmask and fmask

Re: Windows executable have directory permission in udev automount

I've corrected "-u" with "--fmask"

ACTION=="add", ENV{dir_name}!="", RUN+="/bin/su tomk -c '/usr/bin/pmount -A --fmask 177 --dmask 066 %N %E{dir_name}'"

and nothing changed.
My problem is: new.txt has right permissions, new.exe no: it's executable.
Any help without useless sarcasm?

You are correct.  That came across with a lot more sarcasm and a lot less humor than I had planned.

Apologies.
