file - folder permission issues


Hi all,

I have two users, one is an application user, through application is installed and one is a readonly user which is used by users to view log files.

There is an repetitive issue where I have to give permission to certian application logs to 755 recursively to be able to be viewed by user readonly.

Quote:
apps user:


id
uid=60000(apps) gid=8500(dba) groups=8500(dba)

umask
0022


ls -l

-rwxr-xr-x 1 apps dba 630339 Oct 11 15:59 server.log

new files created with this user

touch a; ll a
-rw-r--r-- 1 apps dba 0 Oct 11 16:04 a
Quote:
readonly user



id
uid=502(readonly) gid=54321(oinstall) groups=54321(oinstall),60000(apps)

umask
0022


readonly user has been put into apps group. but could not write to the folder, which works as expected.

touch a
touch: cannot touch `a': Permission denied

But new files are created with permission 644 due to which they are not been able to be viewd by readonly user, and permissions have to be given recursicvely on folder with chmod -R 755 /path/to/log folder to make them viewable by readonly user.

Kindly suggest how to acheive that the files created by apps user in the logs folder will have permission of 755 or 750 so that readonly user can view them.

Any user will be able to read file if there is 'read' permission is available on a file for related group or others. Meanwhile if you want that user to have full permission, then define a new umask value for 'appsuser'. To do this, just add following line at the end appuser's .bashrc or .profile file:
Code:
umask 000
Then source the file:
Code:
~$ source .bashrc
OR
~$ source .profile

Not much sure, but as far as I am concerned, it's showing 'sticky bit' permission (Read here: http://www.tldp.org/LDP/intro-linux/...ect_03_04.html).

The . is to show the condition of any ACLs that may be on the file. A "." indicates no ACLs. If an ACL entry did exist, it would show a + sign. You can retrieve the ACLs associated with a file using "getfacl". On files with no ACL it will just list the user/group/other access modes on three lines. (see manpage on getfacl for more info.
