Most likely the script is trying to execute some other scripts and/or executables on the same filesystem, so that's why it fails. $ mount | grep tbig /dev/sdb1 on /media/tbig type fuseblk (rw,noexec,noatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096) $ bash -x /media/tbig/test.sh + echo 'Successful!' Successful! + source /media/tbig/sourced.sh ++ echo Sourced Sourced + /media/tbig/executed.sh /media/tbig/test.sh: line 7: /media/tbig/executed.sh: Permission denied + bash /media/tbig/executed.sh Executed! In this is case it's probably easiest to just mount the filesystem with 'exec'. Kind regards, Andrei -- http://wiki.debian.org/FAQsFromDebianUser signature.asc Description: PGP signature

Remember that "users" implies "noexec", too. If you want to keep "users", you should add "exec" explicitly.

If possible please refrain from sending html to the list, as the result on the receiver's end is unpredictable. If you really can't avoid it, don't bother adding any formatting (bold, etc.), it will only make things more difficult for us to read.

Actually you don't, you can just use 'bash myshellscript.sh' instead ;)
If this doesn't work for you (why?) read below.

That line has several issues, e.g. in Debian users are not automatically
members of the 'users' group.
'uid': use the number shown by running 'id' as your user. It is '1000'
for the user created during the installation process.
'gid=users' is needed only if you need the flash drive to be accessible
by more users in which case you must add them manually to that group
('adduser alice users').
If only you need access use your own gid instead (should be the same as
your uid).
'dmask'/'fmask' are redundant if you already specify 'umask=0'. Normally
I would suggest 'dmask=002' and 'fmask=113'. but you need 'fmask=003' or
similar, so it doesn't make a big difference.
'exec' is only needed because you specify 'users' (do you need it?). See
'man mount' for what it does.
'x-systemd.device-timeout' is redundant as well due to 'noauto' (systemd
shouldn't even attempt to mount it).
Kind regards,
Andrei

That means that "make-fstab" would construct an fstab from the currently mounted devices? I can't help it, that sounds somewhat daredevil to me.

But, as I said, if it's not a frequent operation, you might want to either mount manually or let some automounter do the job for you (most desktop environments do the latter). Me? I prefer to mount manually: when lights get out, I at least get some direct feedback on my actions ;-) Cheers -- tomás signature.asc Description: Digital signature
Re: cannot execute make-fstab in Debian?
Sorry about that. I should have tested it first. What I'm trying to achieve is to be able to save files and to run executable files (like .sh file) from an NTFS partition of the hard drive, as well as from a USB flash drive. It seems that in Debian, I can already do that in an NTFS partition of the hard drive, can you confirm? As for the flash drive, I have to add this line to the /etc/fstab file (so I can run .sh files from the flash drive) *UUID=2E7B-BA02 /media/myflashdrive vfat user,rw,noauto,uid=1000,gid=users,umask=0,dmask=0,fmask=0,users,exec,x-systemd.device-timeout=5s, 00 * In the other distro, I would delete the existing /etc/fstab file, execute *sudo make-fstab* in order to generate a new fstab file, and in that fstab file there would be a line for the flash drive. I would then edit that line to make it look like the one above so that I can run .sh files from the flash drive. As make-fstab command doesn't exist in Debian, I just added the above line to /etc/fstab and it seems to have solved the problem. But can you confirm that line as well? I'm not an expet. Thank you!

Perhaps you might tell us what the error message looks like. My guess is that there is no command with that name.
