MT(1) UNIX Programmer's Manual MT(1) NNAAMMEE mt - magnetic tape manipulating program SSYYNNOOPPSSIISS mmtt [ --ff _t_a_p_e_n_a_m_e ] _c_o_m_m_a_n_d [ _c_o_u_n_t ] DDEESSCCRRIIPPTTIIOONN _M_t is used to give commands to a magnetic tape drive. If a tape name is not specified, the environment variable TAPE is used; if TAPE does not exist, _m_t uses the device /_d_e_v/_r_m_t_1_2. Note that _t_a_p_e_n_a_m_e must reference a raw (not block) tape device. By default _m_t performs the requested operation once. Operations may be performed multiple times by specifying _c_o_u_n_t. The available commands are listed below. Only as many char- acters as are required to uniquely identify a command need be specified. eeooff, wweeooff Write _c_o_u_n_t end-of-file marks at the current position on the tape. ffssff Forward space _c_o_u_n_t files. ffssrr Forward space _c_o_u_n_t records. bbssff Back space _c_o_u_n_t files. bbssrr Back space _c_o_u_n_t records. rreewwiinndd Rewind the tape (_C_o_u_n_t is ignored). oofffflliinnee, rreewwooffffll Rewind the tape and place the tape unit off-line (_C_o_u_n_t is ignored). ssttaattuuss Print status information about the tape unit. _M_t returns a 0 exit status when the operation(s) were suc- cessful, 1 if the command was unrecognized, and 2 if an operation failed.
