Change all permissions
- Anmelden oder Registrieren um Kommentare zu schreiben
I just installed Trisquel, migrating from Mac OS X. I made a backup of my home directory in OS X onto an external hard drive, but the permissions were set for my old user in OS X, so I can't read the files in Trisquel. How would I change the permissions in the whole directory tree?
sudo chown -R `whoami`:`whoami` /path/to/home/folder
I am a member!
Assuming the username gameboy, and the directory called
files-from-osx,do this in a terminal:
sudo -i
enter your password
chown --recursive gameboy /home/gameboy/files-from-osx/
exit
chmod --recursive 755 /home/gameboy/files-from-osx/
HTH,

I'm not sure if it worked, because this is a sample of much of the output:
"chown: changing ownership of `/media/320 Gigabyte/Mac Mini Home Folder Backup/': Read-only file system"
The files are on an external hard drive, connected by USB.
I also noticed that there is no option to delete files on that drive, the 'Move to Trash' option on the right-click menu is grayed out.

If your name shows up in the output of
ls -la /media/320\ Gigabyte/Mac\ Mini\ Home\ Folder\ Backup/'
you own the files. I think the owner's and group's names are in the 4th
and 5th columns of the listing.
What is the output of
chmod --recursive 755 /media/320\ Gigabyte/Mac\ Mini\ Home\ Folder\
Backup/'
This 'chmod' command sets permissions such that you can do everything to
the files, but your group and all other users can only read and execute.
It doesn't actually say my name, but here is the output.
I'm not sure, it was formatted as HFS+ with Mac OS X 10.6.8, and I don't know how to read permissions yet.

Oh, I'm not sure how to work with those formats in Trisquel. Whenever I
want to exchange files, using a USB drive, I format the file system as
FAT on the USB. When sneaker-netting files from one machine running
GNU/Linux to another, I suppose you can format the USB as ext3, ext4, or
xfs?
Looks like this is a fairly common issue. If my web search-fu is strong, this happens because of a problem with the file system.
The best solution would be to copy all you wish to save off the disk and then reformat it. Or if you're a gambler, you could fsck [1] it. :)
If I try to copy it, it says "Permission Denied", or something like that.

I ended up copying and reformatting one of these after returning home to
Trisquel from another distro that messed things up. Long story. LOL.
Also, if you haven't broken down the Mac Mini, you can start it, connect
it to your network, find it on your Trisquel box (open the desktop
folder called "network servers"), and log into your Mini from there.
Once connected, working with the remote folder is just like working with
any folder already on the Trisquel side.
I'm running Trisquel on my Mac Mini as my primary machine. I have a Time Machine backup, too, (uses version control) but I just copied my OS X home folder to an external drive, then installed Trisquel.
Try Nautilus (File Manager) as root.
Alt+F2 > gksu nautilus > type your password.
Or in Terminal:
sudo nautilus
your password
And change the permissions with right click in the folder > properties.
