Problem while removing file by group user
I am experiencing a problem while removing the a file by group user.
For example - I have two users say A and B. One CSV file is created by A user with 774 (rwxrwxr--)permission. The directory(the csv file is created inside this) permission is set to 755(rwxr-xr-x). Now, user B and A are in same group. But I am unable to remove the file by B user as it is giving “Permission Denied” error. The umask has been set to 002 for user A. Could anybody please suggest how can I solve this issue. Is there any problem with the permission?
Thanks in advance
