Is it possible to set up permision on the file such owner can create the file & write into that but can not delete file.

Immediate answer highly appreciated

Yes. Deleting files is dependent on the directory's permissions. So if you set "~/folder" to be read-only, then you can't delete any files inside "~/folder", and if you then set "~/folder/file" to have write permissions, you will have a file that can be written to but not deleted

Yes:

Code:

root@CW8:/tmp# touch dir/test.file
root@CW8:/tmp# chown c:users dir/test.file
c@CW8:/tmp/dir$ echo xxx > test.file 
c@CW8:/tmp/dir$ rm test.file
rm: cannot remove `test.file': Permission denied
