chown, chgrp - change owner or group
chown owner file ...
chgrp group file ...
_C_h_o_w_n changes the owner of the _f_i_l_e_s to _o_w_n_e_r. The owner may be either a decimal UID or a login name found in the password file.
_C_h_g_r_p changes the group-ID of the _f_i_l_e_s to _g_r_o_u_p. The group may be either a decimal GID or a group name found in the group-ID file.
Only the super-user can change owner or group, in order to simplify as yet unimplemented accounting procedures.
