OOPPTTIIOONNSS
--rroooott _r_o_o_t_p_a_t_h
Specify root of index tree.
--ddeevv _d_e_v_i_c_e The name of the reader device.
--vv Turn on verbose mode which prints status dur-
ing operation.
--cclloobbbbeerr Overwrite the disk index with the tape index.
--nnooiinnddeexx Restore the thdr file from tape but don't
rebuild the index. This implies --ssaavvee.
--ssaavvee Save the thdr file after index is restored.
--ffiirrsstt _f_i_r_s_t-_f_i_l_e
Number of first thdr file to restore. (0 ==
first file on tape).
--llaasstt _l_a_s_t-_f_i_l_e
Number of last thdr file to restore. (-1 ==
last file on tape).
--mmaattcchhPPaatthh _p_a_t_h_n_a_m_e
Restore only files that match the path _p_a_t_h_-
_n_a_m_e according to Unix globbing rules.
--mmaattcchhttbbuuff _t_b_u_f-_n_u_m
Restore only files that match the tbuf number
_t_b_u_f-_n_u_m according to Unix globbing rules.
--bbeeffoorree _d_a_t_e Restore only entries archived before _d_a_t_e.
--aafftteerr _d_a_t_e Restore only entries archived after _d_a_t_e.
--bbuuffssiizzee _b_y_t_e_s_i_z_e
Read from tape in _b_y_t_e_s_i_z_e units.

DDEESSCCRRIIPPTTIIOONN
JJbbuuiilldd is a system manager's utility for the Jaquith system.
It's purpose is to rebuild Jaquith's disk index from tape in
the event of disk crash.
Jbuild processes a single Jaquith tape by restoring a
sequence of index (thdr) file, parsing them, and rebuilding
the tree structure on disk. Several arguments control the
details of the restoration: The --ffiirrsstt and -last arguments
limit the range of thdr files which are read from tape. The
--mmaattcchhppaatthh argument restricts restoration to user file path-
names which match _p_a_t_h_n_a_m_e. The --nnooiinnddeexx option inhibits
the rebuilding of the disk index entirely; only the raw thdr
files are restored.
Jbuild is not network-aware since it is not for use by
clients. It assumes that it has direct access to the
readers.
_d_a_t_e is of the form _D_a_t_e_S_p_e_c[:_T_i_m_e_S_p_e_c]. _T_i_m_e_S_p_e_c is of the
form [hh[:mm[:ss]]], and _D_a_t_e_S_p_e_c is of the form
dd-month[-yyyy]. Month is the first 3 letters of the month;
all others are numbers. The '/' character is a substitute
for '-' and '.' may be used instead of ':'.
FFIILLEESS
Jbuild creates a temporary work file in the Jaquith root
called rebuild._p_i_d. The work file will be renamed
_a_r_c_h/thdr._n_u_m_b_e_r after the thdr file has been restored to
its archive, or thdr._p_i_d._c_o_u_n_t, if the file appears to be
bogus.
BBUUGGSS
Jbuild can restore only one volume at a time; several invo-
cations may be necessary to restore an entire logical
archive.
