i try to move one large .dmp file
to other disk space.
let say from /export/m.dmp to /tmp directory
in export the files is owned by sysops
$ -rwxr-xr-x 1 sysops dba
when i cp the file to /tmp
the owner is root.
i try to move using sysops id but get error
'no permission,access denied'
how can i grant back the file to sysops.
