_O_r_d_i_s_t is a program to maintain identical copies of files over multiple
hosts. It preserves the owner, group, mode, and mtime of files if
possible and can update programs that are executing. _O_r_d_i_s_t reads
commands from _d_i_s_t_f_i_l_e to direct the updating of files and/or
directories. If _d_i_s_t_f_i_l_e is `-', the standard input is used. If no ----ffff
option is present, the program looks first for `distfile', then
`Distfile' to use as the input. If no names are specified on the command
line, _o_r_d_i_s_t will update all of the files and directories listed in
_d_i_s_t_f_i_l_e. Otherwise, the argument is taken to be the name of a file to
be updated or the label of a command to execute. If label and file names
conflict, it is assumed to be a label. These may be used together to
update specific files using specific commands.
The ----cccc option forces _o_r_d_i_s_t to interpret the remaining arguments as a
small _d_i_s_t_f_i_l_e. The equivalent distfile is as follows.
( _n_a_m_e ... ) -> [_l_o_g_i_n@]_h_o_s_t
install [_d_e_s_t] ;
Other options:
----dddd Define _v_a_r to have _v_a_l_u_e. The ----dddd option is used to define or
override variable definitions in the _d_i_s_t_f_i_l_e. _V_a_l_u_e can be the
empty string, one name, or a list of names surrounded by parentheses
and separated by tabs and/or spaces.
----mmmm Limit which machines are to be updated. Multiple ----mmmm arguments can be
given to limit updates to a subset of the hosts listed the _d_i_s_t_f_i_l_e.
----nnnn Print the commands without executing them. This option is useful for
debugging _d_i_s_t_f_i_l_e.
----qqqq Quiet mode. Files that are being modified are normally printed on
standard output. The ----qqqq option suppresses this.
----RRRR Remove extraneous files. If a directory is being updated, any files
that exist on the remote host that do not exist in the master
directory are removed. This is useful for maintaining truly
identical copies of directories.
----hhhh Follow symbolic links. Copy the file that the link points to rather
than the link itself.

oooorrrrddddiiiisssstttt((((1111cccc)))) oooorrrrddddiiiisssstttt((((1111cccc))))
----iiii Ignore unresolved links. _O_r_d_i_s_t will normally try to maintain the
link structure of files being transferred and warn the user if all
the links cannot be found.
----vvvv Verify that the files are up to date on all the hosts. Any files
that are out of date will be displayed but no files will be changed
nor any mail sent.
----wwww Whole mode. The whole file name is appended to the destination
directory name. Normally, only the last component of a name is used
when renaming files. This will preserve the directory structure of
the files being copied instead of flattening the directory
structure. For example, renaming a list of files such as ( dir1/f1
dir2/f2 ) to dir3 would create files dir3/dir1/f1 and dir3/dir2/f2
instead of dir3/f1 and dir3/f2.
----yyyy Younger mode. Files are normally updated if their _m_t_i_m_e and _s_i_z_e
(see _s_t_a_t(2)) disagree. The ----yyyy option causes _o_r_d_i_s_t not to update
files that are younger than the master copy. This can be used to
prevent newer copies on other hosts from being replaced. A warning
message is printed for files which are newer than the master copy.
----bbbb Binary comparison. Perform a binary comparison and update files if
they differ rather than comparing dates and sizes.
----DDDD Print debugging messages.
_D_i_s_t_f_i_l_e contains a sequence of entries that specify the files to be
copied, the destination hosts, and what operations to perform to do the
updating. Each entry has one of the following formats.
<variable name> `=' <name list>
[ label: ] <source list> `->' <destination list> <command list>
[ label: ] <source list> `::' <time_stamp file> <command list>
The first format is used for defining variables. The second format is
used for distributing files to other hosts. The third format is used for
making lists of files that have been changed since some given date. The
_s_o_u_r_c_e _l_i_s_t specifies a list of files and/or directories on the local
host which are to be used as the master copy for distribution. The
_d_e_s_t_i_n_a_t_i_o_n _l_i_s_t is the list of hosts to which these files are to be
copied. Each file in the source list is added to a list of changes if
the file is out of date on the host which is being updated (second
format) or the file is newer than the time stamp file (third format).
Labels are optional. They are used to identify a command for partial
updates.
Newlines, tabs, and blanks are only used as separators and are otherwise
ignored. Comments begin with `#' and end with a newline.

Variables to be expanded begin with `$' followed by one character or a
name enclosed in curly braces (see the examples at the end).
The source and destination lists have the following format:
<name>
or
`(' <zero or more names separated by white-space> `)'
The shell meta-characters `[', `]', `{', `}', `*', and `?' are
recognized and expanded (on the local host only) in the same way as
_c_s_h(1). They can be escaped with a backslash. The `~' (tilde) character
is also expanded in the same way as _c_s_h but is expanded separately on the
local and destination hosts. When the ----wwww option is used with a file name
that begins with `~', everything except the home directory is appended to
the destination name. File names which do not begin with `/' or `~' use
the destination user's home directory as the root directory for the rest
of the file name.
The command list consists of zero or more commands of the following
format.
`install' <options> opt_dest_name `;'
`notify' <name list> `;'
`except' <name list> `;'
`except_pat' <pattern list> `;'
`special' <name list> string `;'
The _i_n_s_t_a_l_l command is used to copy out of date files and/or directories.
Each source file is copied to each host in the destination list.
Directories are recursively copied in the same way. _O_p_t__d_e_s_t__n_a_m_e is an
optional parameter to rename files. If no _i_n_s_t_a_l_l command appears in the
command list or the destination name is not specified, the source file
name is used. Directories in the path name will be created if they do
not exist on the remote host. To help prevent disasters, a non-empty
directory on a target host will never be replaced with a regular file or
a symbolic link. However, under the `-RRRR' option a non-empty directory
will be removed if the corresponding filename is completely absent on the
master host. The _o_p_t_i_o_n_s are `-RRRR', `-hhhh', `-iiii', `-vvvv', `-wwww', `-yyyy', and
`-bbbb' and have the same semantics as options on the command line except
they only apply to the files in the source list. When specifying several
options, each one mmmmuuuusssstttt begin with a hyphen. For example, use -bbbb -vvvv
instead of -bbbbvvvv, which is interpreted as the destination directory. The
login name used on the destination host is the same as the local host
unless the destination name is of the format ``login@host".
The _n_o_t_i_f_y command is used to mail the list of files updated (and any
errors that may have occurred) to the listed names. If no `@' appears in
the name, the destination host is appended to the name (e.g., name1@host,
name2@host, ...).

The _e_x_c_e_p_t command is used to update all of the files in the source list
eeeexxxxcccceeeepppptttt for the files listed in _n_a_m_e _l_i_s_t. This is usually used to copy
everything in a directory except certain files.
The _e_x_c_e_p_t__p_a_t command is like the _e_x_c_e_p_t command except that _p_a_t_t_e_r_n
_l_i_s_t is a list of regular expressions (see _e_d(1) for details). If one of
the patterns matches some string within a file name, that file will be
ignored. Note that since `\' is a quote character, it must be doubled to
become part of the regular expression. Variables are expanded in _p_a_t_t_e_r_n
_l_i_s_t but not shell file pattern matching characters. To include a `$',
it must be escaped with `\'.
The _s_p_e_c_i_a_l command is used to specify _s_h(1) commands that are to be
executed on the remote host after the file in _n_a_m_e _l_i_s_t is updated or
installed. If the _n_a_m_e _l_i_s_t is omitted then the shell commands will be
executed for every file updated or installed. The shell variable `FILE'
is set to the current filename before executing the commands in _s_t_r_i_n_g.
_S_t_r_i_n_g starts and ends with `"' and can cross multiple lines in _d_i_s_t_f_i_l_e.
Multiple commands to the shell should be separated by `;'. Commands are
executed in the user's home directory on the host being updated. The
_s_p_e_c_i_a_l command can be used to rebuild private databases, etc. after a
program has been updated.
The following is a small example.
HOSTS = (sequoia alic@redwood)
FILES = (/d1/project/{src,bin,lib,doc,dbm})
EXLIB = (acct.dir acct.pag)
${FILES} -> ${HOSTS}
install -R ;
except /d1/project/dbm/${EXLIB} ;
special /d1/project/dbm/acct "mkdbm $FILE" ;
srcs:
/d1/project/src -> yosemite
except_pat ( \\.o\$ /RCS\$ ) ;
PROGS = (dog flight arena)
update:
/usr/src/demos/${PROGS} -> lassen
install /usr/local/demos ;
notify bob;
${FILES} :: stamp.shasta
notify chuck@shasta ;

A complaint about mismatch of ordist version numbers may really stem from
some problem with starting your shell.
BBBBUUUUGGGGSSSS
Source files must reside on the local host where ordist is executed.
There is no easy way to have a special command executed after all files
in a directory have been updated.
Variable expansion only works for name lists; there should be a general
macro facility.
_O_r_d_i_s_t aborts on files which have a negative mtime (before Jan 1, 1970).
There should be a `force' option to allow replacement of non-empty
directories by regular files or symlinks. A means of updating file modes
and owners of otherwise identical files is also needed.
_O_r_d_i_s_t doesn't interpret properly multiple options to the 'install'
command unless each one begins with a hyphen.
On 4.3BSD, the local _r_d_i_s_t expects the remote _r_d_i_s_t to reside in
/usr/ucb. On IRIX, it resides in /usr/bsd. To allow the 4.3BSD _r_d_i_s_t to
communicate with the IRIS, create a symbolic link for /usr/ucb:
su
ln -s /usr/bsd /usr/ucb
