TclX interface to the command to change the owner of one or more files.
Some operating systems and/or file systems won't support this operation.
chown [-fileid] owner | {owner group}
Set owner of each file in the list filelist to owner, which
can be a user name or numeric user id. If the first parame-
ter is a list, then the owner is set to the first element of
the list and the group is set to the second element. Group
can be a group name or numeric group id. If group is {},
then the file group will be set to the login group of the
specified user.
If the option -fileid is specified, filelist is a list of
open file identifiers rather than a list of file names.
This option is not available on all Unix systems. Use the
infox have_fchown command to determine if this functionality
is available.
The chown command is not available on Windows 95/NT.
