everybody (owner - group - others) has got execute rights on executable files: rwx r-x r-x.This has to be true for all data files in all folders and sub-folders. everybody (owner - group - others) hasgot all rights on the data files: rw- rw- rw.This has to be true for all folders and sub-folders. everybody (owner - group - others) has got all rights on the folders: d rwx rwx rwx.It should not be necessary to change ownership and/or access permissions on the ext2 filesystem of your USB disk everytime, once you have setup the folder permissions in such a way that It is meant to be opened and used by anybody/everybody on any Linux machine, to provide true portability and if anything gets lost, destroyed or damaged. Previously it was created by root in another Linux and This was the source of my problem? when I tried to run it as a "normal account" on Mint.Īnd before anybody gets horified and concerned about leaving everything open on this drive to anybody - it doesn't matter, because it is always backed up and protected somewhere else (after all you can't really trust 100% some usb drive?). I want all the files in this drive to be readable, modifiable and openable by everybody and anybody, so that if I connect it to another Linux machine it simply runs without any questions. I appreciate that it is not Mint issue, but this is as good a place to ask for advice as one can get, so I hope you guys don't mind me raising it as a topic?Īt the moment the permissions look as follows: Otherwise I would welcome any suggestions which would help me to make my calibre on usb drive truly portable. Next idea is to get Flash usb memory and format it FAT32 to se if this gets around all this permission stuff. ![]() ![]() In theory it is perfect for me because it is truly portable, but it is a bummer if I have to fart around with permission every time I connect it to another machine The whole idea is to have both the library and calibre totally separate from the system and capable of running on it's own as long as it is connected to some Linux machine. I grasped (eventually) the problem with permissions created by using normal user accout to create portable calibre installation. I am moving from XP (and from Puppy Linux) hence my need to adjust mentally to the mainstream Linux frame of mind I understand (and wasn't trying to suggest) that my problems aren't Mint specific Thank you for comprehensive and helpful explanation. In order to check, on the second system, where the problem occurs, open a terminal window.Įxecute the following commands and post the screen output here: ![]() As a consequence the portable Calibre installation is owned by an unknown user and your account on the second system is missing the permissions to read, write or execute Calibre files. On the second system, either you use a different account or the accound has got the same name, but a different UID. ![]() As a consequence the whole portable Calibre installation will be owned by this account. On the system where you copied the portable installation to the external USB hdd, you will have done so with your normal user account. The Linux access permission concept is based on owner, group and others and on the permissions which can be granted to owner, group and others. They are not specific to Linux Mint, but common to any Linux and Unix system. Provided the answer is "yes, it has", then the normal Linux ownership and access permission rules apply. The USB hdd has been formatted with ext3 or ext4, i.e.
