Changes the attributes of an existing file or directory. (Native
Mode) Syntax | |
ALTFILE[ FILE=] filename [ ] ;OWNER=ownername] ] [ [ ;GROUPID=] POSIXgroupname] |
Parameters | |
- filename
The filename of the object to be altered, specified
in either MPE or HFS syntax. The filename
may name a file, hierarchical directory, root, MPE group or account.
Note that MPE groups or accounts can ONLY be named via HFS (Hierarchical
File System) syntax. Temporary files are not recognized. This is a required parameter. You may not use wildcards, back-reference
a file equation, or name a system-defined file such as $NULL. If the filename is in MPE syntax and it has a lockword, do
NOT include the lockword on the command line, or you will get an
error. - ownername
The name of the user who will become the owner (UID)
of filename. This ownername
must already exist on the system. Default is for the UID of the
file to remain unchanged. Note that no qualification is done on
this name; it must be fully specified. To have the ownername
upshifted, enclose it in quotes. - POSIXgroupname
The name of the POSIX group (GID) that this file
will belong to. This POSIXgroupname must
already exist on the system. You cannot use this parameter to change
the GID of an MPE group or account. Default is for the file to retain
its previous GID. To have POSIXgroupname
upshifted, enclose it in quotes.
Operation Notes | |
You use the ALTFILE
command to alter a file's characteristics. Currently the attributes
that you may modify are the owner (UID) and POSIX group (GID) for
a file, hierarchical directory, MPE group or account, with the restriction
that you may not alter the GID for MPE groups or accounts. You must have the appropriate privilege to change the requested
attribute(s). In order to change the UID of a file, you must be
one of the following: The file's account manager (your logon
account matches the GID of the file and you have MPE/iX account
manager (AM) capability). In this case, ownername
must specify a user belonging to the account manager's logon account. A system manager (a user who has the MPE/iX system
manager (SM) user capability). In this case, ownername
may specify any user existing in the user database.
In order to change the GID of a file, you must be one of the
following: The file owner (your logon name matches
the UID of the file). In this case, POSIXgroupname
must specify your logon account. The file's account manager (your logon account matches
the GID of the file and you have the MPE/iX account manager (AM)
capability). In this case, POSIXgroupname
must specify the account manager's logon account. A system manager (you have MPE/iX system manager
(SM) capability). In this case, POSIXgroupname
may specify any GID existing in the group database.
You may issue the command once to modify multiple attributes.
If you specify multiple attributes, all modifications must succeed
for any to take effect. If you enter no attributes, the command
has no effect on the specified file. Related Information | |
