I set umask ugo=rwx for a test user.

I then vi a test file (tree). When it's created it's not getting X, just RW.

"tree" [New file] 1 line, 5 characters
$ ls -ltr
total 672
-rw-rw-r-- 1 root sys 5296 Apr 3 06:33 ps_data
-rw-r--r-- 1 root other 5 Apr 25 12:41 speckeysd.lock
-rw------- 1 root other 310984 Apr 25 12:41 dtdbcache_:0

-rw-rw-rw- 1 rallen cdsweb 5 May 16 12:46 tree
$ umask
00
$


When I create a file it has RW for UGO, but not X. Why isn't execute being set for UGO?

Thanks!
