ALTFILE
This command changes the attributes of an existing file or directory.
SYNTAX
ALTFILE [FILE=] filename [[;OWNER=] ownername] [[;GROUPID=] POSIXgroupname]
PARAMETERS
filename The file name of the object to be altered. 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 cannot use
wildcarding to specify file names, nor can you use
back-referenced file equations. This parameter cannot
name a system-defined file (such as $NULL). You can
specify file names using both MPE and HFS syntaxes.
MPE-syntax names may not include lockwords; the lockword
for a lockworded file is not needed for this command to
succeed, and if included in the filename results in 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. This name will be
upshifted if it is NOT quoted. [Optional]
POSIXgroupname The name of the group (GID) that this file will belong
to. This POSIXgroupname must already exist on the
system. This parameter cannot be used to change the GID
of an MPE group or account. The default is for the file
to retain its previous GID. This name is upshifted when
you enclose it in quotes.
Operation Notes
* Usage
You use the ALTFILE command to alter a file's characteristics.
You can modify the owner (UID) and POSIX group (GID) for a file,
hierarchical directory, MPE group or account. You cannot alter
the GID of MPE groups or accounts.
* Required Capabilities
The user must have the appropriate privilege to change the
requested attribute. To change the UID of a file, you must be one
of the following:
* The file's account manager whose logon account matches the
GID of the file and who has the MPE/iX account manager
capability. In this case, ownername must specify a user
belonging to the account manager's logon account.
* A system manager who has the MPE/iX system manager user
capability. In this case, ownername may specify any user
existing in the user database.
To change the GID of a file, you must be one of the following:
* The file owner (a user whose logon name matches the UID of
the file). In this case, POSIXgroupname must specify the
user's logon account.
* The file's account manager whose logon account matches the
GID of the file and who has the MPE/iX account manager (AM)
user capability. In this case, POSIXgroupname must specify
the account manager's logon account.
* A system manager who has the MPE/iX system manager user
capability. In this case, POSIXgroupname may specify any
GID existing in the group database.
You can use ALTFILE to modify multiple attributes at the same time. If
you try modifying multiple attributes, all changes must succeed for any
to take effect. If you do not specify any attributes, the command has no
effect on the file specified.
