Re: Can not set execute permission to file in usb storage media with fat32 format
I want to execute some script file in usb storage media with fat32 format, but I can not set execute permission to them with chown +x. What shall I do? I don't think chown +x is possible on an alien FS. On my usb stick with FAT32, all files look like they're executables.

Re: Can not set execute permission to file in usb storage media with fat32 format
Very strange. The usb stick was mounted by debian system automatic. If I login with root and plug usb stick, I can execute the script after automatic mounting. But if I login with user and plug usb stick, I cann't execute it after automatic mounting with message permission denied. 2010/12/16 Manon Metten manon.met...@gmail.com I want to execute some script file in usb storage media with fat32 format, but I can not set execute permission to them with chown +x.

You can dump all of the mount information with the mount command and trim down to just that device with grep. $ mount | grep /media I expect it might say something like 'noexec' there.

The kernel uses an adaptor layer to make it mostly appear as a Unix filesystem but it is far from perfect. Trying to ignore that and act like it is a Unix filesystem is setting yourself up for a world of hurt. Bob signature.asc Description: Digital signature

Re: Can not set execute permission to file in usb storage media with fat32 format
I think that some extra security options were defined with automatic mounting also. But I don't find where to change them. The mount information as below. $ mount | grep /media /dev/sdb1 on /media/6361-6365 type vfat (rw,nosuid,nodev,uhelper=udisks,uid=0,gid=0,shortname=mixed,dmask=0077,utf8=1,showexec,flush) Either root 2010/12/16 Bob Proulx b...@proulx.com gulfstream wrote: Very strange.
