We had a case where we wanted two different applications (run by different users) to be able to read and write from the same file system.
\nThis is how we solved this problem:<\/p>\n

    \n
  1. Create a group which these users will belong to :[shell]groupadd GROUP_NAME[\/shell]<\/li>\n
  2. Edit user1 and user2 to be a member of this group:[shell]
    \nusermod -a -G GROUP_NAME user1 ;
    \nusermod -a -G GROUP_NAME user2;
    \n[\/shell]<\/li>\n
  3. Create a shared directory. In our case, it had to be the document root for an Apache site. Thus we chose the location SHARED_FOLDER<\/li>\n
  4. Now we need to change the group of this folder :[bash]chgrp -R GROUP_NAME SHARED_FOLDER [\/bash]<\/li>\n
  5. We’ll also need to grant the group write access on this folder :[bash]chmod g+w SHARED_FOLDER [\/bash]<\/li>\n
  6. Now we’ll need to set the GroupID flag on this folder. For a directory, the set-groupID flag means that all files created inside that directory will inherit the group of the directory. Without this flag, a file takes on the primary group of the user creating the file. This property is important to people trying to maintain a directory as group accessible. The subdirectories also inherit the set-groupID property. (http:\/\/www.dartmouth.edu\/~rc\/help\/faq\/permissions.html).[bash]chmod +s SHARED_FOLDER[\/bash]<\/li>\n
  7. Now in your .bashrc \/ .bash_profile, set the umask as 002. Setting this umask ensures that all the newly created files by this user will have the permission “rw-rw-r”. Thus giving the group write permission.:\u00a0[bash] umask 002 [\/bash]<\/li>\n<\/ol>\n

    Now when either of the users create any file in the SHARED_FOLDER, all the users of this group will have the read\/write permissions on that file. Not only this, these permissions will be on the subfolders and the files with-in that folder as well.<\/p>\n

    But, if any of these users create a file outside the SHARED_FOLDER, the primary group of that file\/folder will be the same as the primary group of that user. Thus files\/folder only in the SHARED_FOLDER are shared between these users.<\/p>\n

    This is just one of the many great abilities that Linux provides.<\/p>\n

    Hope this saves you some time.<\/p>\n

    Your feedback and suggestions are welcome.<\/p>\n
