im trying to access this Download folder from a different Linux distribution, I can open files but cannot save changes to them. I am not sure what "502" means. Do i have to change the folder ownership from the Linux distro in which it was created or can i do it from inside tinycore? Also, I still want to be able to use the folder from its original Linux distro, but want to be able to open and modify files in there from Tinycore as well.

Hi h2sammo
Users and groups are assigned numbers. There is no 502 assigned in Tinycore so it just shows up as the number. The simplest
way to fix this would be:

Code: [Select]

sudo chmod 757 DownloadsThis will give write access to non 502 users. I'd need to see the directory listing for  Downloads  to tell you what to
change the access rights to for those files.

an excerpt of files inside Downloads folder:

Code: [Select]

tc@box:~$ ls -l /mnt/sdb3/Downloads
total 1043024

btw i tried the command recommended by you but i still dont have access to make changes to that folder.

[h2sammo]

i actually did the following command:

Code: [Select]

sudo chmod 757 /mnt/sdb3/Downloads/*

and now i can modify files in that folder. however, they still show as owned by 502. i dont get it:

Code: [Select]

tc@box:~$ ls -l /mnt/sdb3/Downloads/*
-rwxr-xrwx    1 502      502         964878 Dec 12 04:30 /mnt/sdb3/Downloads/1997_hossain_yardney_US5595839.pdf
-rwxr-xrwx    1 502      502         315247 Dec 15 15:19 /mnt/sdb3/Downloads/1_72V270AH(NMC).pdf

Hi h2sammo
That first command was to give you access to the directory. To allow you to modify the files, try this:

Code: [Select]

cd /mnt/sdb3/Downloads
sudo chmod o=rw *

Hi h2sammo

... and now i can modify files in that folder. however, they still show as owned by 502. i dont get it: ...

There are 3 sets of permissions, user, group, and other. The permissions that we want to modify is for other. User and
group on that device are 502. Other is anyone that is not 502.
