Changing folder permissions and its sub folder and files?

stratotak · 12-27-2011, 07:37 PM

I need to change permission of a folder with sub folder and files in those subfolders to stream video and mp3's to my PS2 .I can right click each folder and sub folder and then each file in that folder to change permission but is there a quick command to to change permission on the main folder and all sub folders and files change.I need to change the permission in "Other" from none to read so the PS2 can read the files.When I right click and change permission in the main folder it doesnt change permission in subfolders.

have you read the chmod man page ?

Code:

man chmod 
--- then ---
su -
cd location/of/the/folder
chmod -R ??? folder

replace the ??? ( or ???? ) with the values
--- or ---
chown

Code:

man chown 
------------
su -
cd  location/of/the/folder

chown -R User:group folder

Following on from the above instead of using values like 655 you can do "chmod -R a+r <foldername>".

I would use the find command to locate all files, and another to locate directories. You need `x' set for directories, but don't want it set for non-executable files.

find dir/ -exec chown user.group '{}' \;
find dir/ -type d -exec chmod 0755 \;
find dir/ -type f -exec chmod 0644 \;

You need to run chown as root, and chmod as root if you own the file.

I'd like to add one small modification to jschiwal's find commands. Change the final "\;" at the end to "\+". The first pattern executes a separate command for each file, but the second runs them in xargs-like batch mode...launching only the minimum number of processes needed to handle the whole file list.

( Be aware though that "\+" only works for commands that are capable of handling multiple files as input, and only if they can be positioned at the end of the argument list. )

Hi,

Use simple chmod ??? -R folder name

4= read
2= write
1= execute

for example

chmod 777 -R foldername

here every one have full permission for read write and execute

$ chmod 0777 foldername
