Shalom,

Arun umask works in a sort of counter-intuitive way.

umask 027
touch umask.027
umask 002
touch umask.002
umask 000
touch umask.000
ll
total 66
drwxr-xr-x 2 root sys 96 Aug 17 13:58 ./
drwxrwxrwx 8 bin bin 33792 Aug 17 13:58 ../
-rw-rw-rw- 1 root sys 0 Aug 17 13:58 umask.000
-rw-rw-r-- 1 root sys 0 Aug 17 13:58 umask.002
-rw-r----- 1 root sys 0 Aug 17 13:58 umask.027


Hope this helps.

Are you creating the file as that particular user? If there is reference of umask in the .profile of the user, then the /etc/profile will be overwritten !!

Please let us know how did you set umask for the user.

Files are always created with a permission of -rw-rw-rw. Therefore, umask 00 leaves the permissions as shown. Only a directory is created with -rwxrwxrwx. NOTE: 777 is a very bad permission for a file. If the file is not a script, then the file has no business having the execute bit set. And allowing a file to have world-writable permission means that the contents will be completely trashed by anyone on the computer.

777 is (wrongfully) used to solve permission problems and (sadly) documented in many beginner Unix books as a 'normal' permission. A 777 file should only be a junk file. All other files should be protected from the 'world' with 664 or 644 permission.
