RE: UNIX question....

Hi Stephen,

The umask is a mask. That is, it masks out bits that would otherwise be set. It cannot turn on bits that would otherwise not be set. When you create an empty file with touch(1), it is assumed to an empty text/data file, not an empty executable file. Therefore the full permissions with a umask of 0 would be 666, not 777. Applying a umask of 2 gives 664. This is correct. However, if you were to create an executable file with that umask, then you would get the 775 that you are after. If you are not creating an executable, then why do you need the execute bits to be on?

Regards,
Steve Adams

A quick question for all you Oracle/UNIX people...... I need to create a file
with the
permissions 775 ( rwxrwxr-x ) and I have set the umask to what all the books
recommend.... with no luck.... The end user cant user CHMOD on the file, so I
need
to have the files created as 775. Any ideas would be much appreciated.

Thanks in advance.

$ umask -S

u=rwx,g=rwx,o=rx
$ touch junk
$ ls -l junk

-rw-rw-r-- 1 oracle dba 0 Jun 2 09:49 junk

       777

• 775

$ umask 002
$ touch junk
$ ls -l junk

-rw-rw-r-- 1 oracle dba 0 Jun 2 09:55 junk
