As explained in the FAQ for this mailing list: * Please post answers back to the list so others can benefit: private conversations don't benefit people who may only be following along on the list or reading the archives later. Now to assist you, here's an actual example cut and pasted from the machine I'm using right now. I have a USB key with vfat filesystem with label "SDS814XHD" as shown here: $ lsblk -f | grep SDS814XHD sdc vfat FAT16 SDS814XHD 843A-B464 Here's 'grep' showing the relevant line in /etc/fstab that allows that particular key to be mounted by any user: $ grep SDS814XHD /etc/fstab LABEL=SDS814XHD /mp/sds814xhd vfat noauto,gid=share,dmask=7007,fmask=7117,shortname=winnt,quiet,user Note in that line the use of the 'user' option as described in 'man mount'. Here's what happens when a plain user 'david' mounts the USB key: $ whoami david $ mount -v LABEL=SDS814XHD mount: /dev/sdc mounted on /mp/sds814xhd. User david owns the files: $ ls -l /mp/sds814xhd total 32 drwxrwx--- 3 david share 16384 1980-01-01 11:00 SDS814XHD drwxrwx--- 2 david share 16384 2024-11-15 19:25 SIGLENT $ umount -v LABEL=SDS814XHD umount: /mp/sds814xhd (/dev/sdc) unmounted I hope that example helps you to do what you need. If you reply, please make sure that your reply goes to the list, not to me. Thanks.
