Cannot create / delete files from directories copied from cdrom

rangalo · 2009-12-24 19:48:45

I copied my backed up projects (mainly java) from a cdrom. Now all the directories inside have wrong permissions (not writable).

Even if I changed the permissions to +w I cannot delete or create files in them. There are many directories. I copied with mc (F5).

Am I making any mistake ? How should I copy them back ?

regards,
Hardik

ls -l a file as an example and paste the result here

If I create the folder and copy other files inside, it works. But still I have to change the permission (+w). Can I copy with default umask ? Should I change something in fstab ?

Here the output ..

everything's read only

rangalo · 2009-12-24 20:07:54

yes, and I want to change that with the last command ... it works .. but I want to avoid changing the permissions...

ewaller · 2009-12-24 20:12:30

try:

sudo chmod -R o+w [insert name of top directory here]

It should recursively change the permission for all files in the directory such that "other" has write privilege. BE SURE you are acting only on the directory you want to change.

That's to be expected, read only medium yields read only files, even after copying to a rw medium.
I would suggest chmod -R u+w instead of chmod -R o+w, the owner (you) is the one that needs write permission not everyone else .

rangalo · 2009-12-25 12:32:30

thanks,

that fixed it.

This is linux flaw, but you can run real backup to preserve ACL
