NAME    [Toc]    [Back]

     oldrdist - remote file distribution program

SYNOPSIS    [Toc]    [Back]

     oldrdist [-nqbRhivwy] [-f distfile] [-d var=value] [-m host]
[name ...]
     oldrdist [-nqbRhivwy] -c name ...  [login@]host[:dest]

DESCRIPTION    [Toc]    [Back]

     oldrdist  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.  oldrdist
reads commands
     from distfile to direct the updating of files and/or  directories.

     Options specific to the first SYNOPSIS form:

     -f  distfile   Use  the  specified distfile.  If distfile is
``-'', the standard
 input is used.

     If either the -f or `-' option is not specified, the program
looks first
     for ``distfile'', then ``Distfile'' to use as the input.  If
no names are
     specified on the command line, oldrdist will update  all  of
the files and
     directories  listed in distfile.  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

     Options specific to the second SYNOPSIS form:

     -c     Forces  oldrdist to interpret the remaining arguments
as a small

           The equivalent distfile is as follows.

                 (name ...) -> [login@] host
                       install [dest];

     Options common to both forms:

     -b    Binary comparison.  Perform a  binary  comparison  and
update files if
           they differ rather than comparing dates and sizes.

     -d var=value
           Define  var  to  have value.  The -d option is used to
define or override
 variable definitions in the distfile.  Value  can
be the empty
           string,  one  name,  or  a list of names surrounded by
parentheses and
           separated by tabs and/or spaces.

     -h    Follow symbolic links.  Copy the file  that  the  link
points to
           rather than the link itself.

     -i     Ignore  unresolved links.  oldrdist will normally try
to maintain
           the link structure of files being transferred and warn
the user if
           all the links cannot be found.

     -m host
           Limit  which  machines are to be updated.  Multiple -m
arguments can
           be given to limit updates to a  subset  of  the  hosts
listed in the

     -n     Print  the commands without executing them.  This option is useful
           for debugging distfile.

     -q    Quiet mode.  Files that are being modified are normally printed on
           standard output.  The -q option suppresses this.

     -R     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.

     -v    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.

     -w    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 (
           dir2/f2  ) to dir3 would create files dir3/dir1/f1 and
           instead of dir3/f1 and dir3/f2.

     -y    Younger mode.  Files are  normally  updated  if  their
mtime and size
           (see stat(2)) disagree.  The -y option causes oldrdist
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

     distfile  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
           [label:]<source list> `::' <time_stamp file>  <command

     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
     source list specifies a list of files and/or directories  on
the local
     host  which  are to be used as the master copy for distribution.  The
     destination list 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

     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:

           `(' <zero or more names separated by whitespace> `)'

     The shell meta-characters `[', `]', `{', `}', `*',  and  `?'
are recognized
     and  expanded  (on  the  local host only) in the same way as
csh(1).  They
     can be escaped with a backslash.  The `~' character is  also
expanded in
     the same way as csh(1) but is expanded separately on the local and destination
 hosts.  When the -w 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 install command is used to copy out of date files and/or
     Each source file is copied to each host in  the  destination
list.  Directories
   are   recursively   copied   in   the   same   way.
opt_dest_name is an optional
 parameter to rename files.  If no install 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  -R  option a non-empty directory will be removed if the
     filename is completely  absent  on  the  master  host.   The
options are -R,
     -h,  -i,  -v,  -w, -y, and -b and have the same semantics as
options on the
     command line except they only apply  to  the  files  in  the
source list.  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 notify 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 except command is used to update all of the files in the
source list
     except for the files listed in name list.  This  is  usually
used to copy
     everything in a directory except certain files.

     The  except_pat  command  is  like the except command except
that pattern
     list is a list of regular expressions  (see  ed(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 pattern
     list but not shell file pattern matching characters.  To include a `$',
     it must be escaped with `'.

     The  special  command is used to specify sh(1) commands that
are to be executed
 on the remote host after the file in name list is  updated or installed.
   If  the  name list 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
     string starts and ends with `"' and can cross multiple lines
in distfile.
     Multiple  commands  to the shell should be separated by `;'.
Commands are
     executed in the user's home directory on the host being  updated.  The
     special  command  can  be used to rebuild private databases,
etc.  after a
     program has been updated.

     The following is a small example:

           HOSTS = ( matisse root@arpa )

           FILES = ( /bin /lib /usr/bin /usr/games
           /usr/lib /usr/man/man? /usr/ucb /usr/local/rdist )

           EXLIB  =  (  Mail.rc  aliases  aliases.dir aliases.pag
crontab dshrc
           sendmail.cf sendmail.fc sendmail.hf  sendmail.st  uucp
vfont )

           ${FILES} -> ${HOSTS}
           install -R ;
           except /usr/lib/${EXLIB} ;
           except /usr/games/lib ;
           special /usr/lib/sendmail "/usr/lib/sendmail -bz" ;

           /usr/src/bin -> arpa
           except_pat ( \.o/SCCS) ;

           IMAGEN = (ips dviimp catdvi)

           /usr/local/${IMAGEN} -> arpa
           install /usr/local/lib ;
           notify ralph ;

           ${FILES} :: stamp.cory
           notify root@cory ;

FILES    [Toc]    [Back]

     distfile     input command file
     /tmp/rdist*  temporary file for update lists

DIAGNOSTICS    [Toc]    [Back]

     A  complaint  about mismatch of oldrdist version numbers may
really stem
     from some problem with starting your shell, e.g., you are in
too many

HISTORY    [Toc]    [Back]

     The oldrdist command appeared in 4.3BSD.

BUGS    [Toc]    [Back]

     Source files must reside on the local host where oldrdist is

     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.

     oldrdist aborts on files which have a negative mtime (before
Jan 1,

     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.
