[Q] Permanently Change Folder Permission

---

I am trying to change the folder permission of the "data/gps" folder to "rwx rwx rwx", by default, it's set to "rwx --- ---".

I can do this by using ES File Explorer but the folder permission gets reverted to the default upon reboot. So I'm guessing ES File Explorer can't change it permanently.

My question is, is there any method that I can use to change it permanently? I have Terminal Emulator installed, but I've never used it before so I don't want to go around messing with it just yet (unless if I can get a confirmation that it'll do what I need it to do).

I would appreciate any help on this. Thanks.

Update:

I tried it with Terminal Emulator, "chmod 777 /data/gps". No luck, the permissions still reverted to default upon reboot.

I was informed that all scripts placed within "/etc/init.d" folder are executed on boot. So I created a shell script file and placed it in that folder.

#Change folder permission
chmod 777 /data/gps

Unfortunately, that didn't work either. I don't know if the script above is incorrect or incomplete. One thing I can't figure out though, are all the scripts in the folder executed with superuser privilege? Correct me if I'm wrong but in order to change the permission for "/data/gps" folder, superuser privilege is required. I have tried the following scripts, nothing works.

#Change folder permission
su chmod 777 /data/gps

#Change folder permission
sudo chmod 777 /data/gps

#Change folder permission
sudo su chmod 777 /data/gps

Anyone with ideas?


UPDATE: I have got this fixed! Turns out that there was nothing wrong with the script. Placing the script in the init.d folder does the trick, it's just that I couldn't get it to work with CM9, it works perfectly on OneCosmic ROM. Maybe CM9 doesn't support init.d?
