ALTFILE
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 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.
