permission assignment

[guna81_m]

iam having four

1. groups - group1,group2,group3,group4

2. each group contain set of users .

3. directory name -- test

using ACL i assigned permission for test directory

group1 : rwx for directory test

group2 : r-x for directory test

if a user from group1 log into unix m/c
and he creates a file (or) directory in test and he can delete as mentioned in acl settings

question :

i have to set a permission in such a way , so that user from group1 can create a file and he should not delete the created file , how can i set the permission for this ?

I don't think you can. Write permission on a directory allows you to add AND remove entries.

(Because that's the way HP-UX is. :-)
If a user puts a file there, why can't he delete it? About the only thing that may be helpful is the sticky bit. This prevents non-owners from removing the file, even if they have Group or Other permission. Useful for /tmp and /var/tmp.

No chattr on HP-UX, just linux with that -i. There is chatr(1) but that only works on load modules dealing with execution properties.

so each and every time user have to use chattr command for created files , it is possibe to write a script ,so that user created files and directory automatically chattr .
