- Thanks for the explanation of the ownerships in the posts, but the
- problem we encountered is that the first name S892999 shown below is
- essentially a user's name.
-
- ~~~~~~~~~~~~~~
- $ dir login.com;3 /security
-
- Directory $DUA0:[STUD.S882000]
-
- LOGIN.COM;3 [S892999,S882000] (RWED,RWED,,)
- ^ ^
- Total of 1 file. | |
- | |
- Another user's name-- --- owner of the account
-
- ~~~~~~~~~~~~~~
-
- I'm just wondering if there is a possiblity that the name of a group
- can be the same as the name of a user. Or is there any way to check
- the group name in VMS? like "ypcat group" in UNIX running NIS.
-
- Thanks in advance.
