.Sh DESCRIPTION
|
|
.Nm Rdist
|
|
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.
|
|
.Nm Rdist
|
|
reads commands from
|
|
.Ar distfile
|
|
to direct the updating of files and/or directories.
|
|
.Pp
|
|
Options specific to the first SYNOPSIS form:
|
|
.Pp
|
|
.Bl -tag -width indent
|
|
.It Fl
|
|
If
|
|
.Ar distfile
|
|
is
|
|
.Sq Fl ,
|
|
the standard input is used.
|
|
.It Fl f Ar distfile
|
|
Use the specified
|
|
.Ar distfile.
|
|
.El
|
|
.Pp
|
|
If either the
|
|
.Fl f
|
|
or
|
|
.Sq Fl
|
|
option is not specified, the program looks first for
|
|
.Dq Pa distfile ,
|
|
then
|
|
.Dq Pa Distfile
|
|
to use as the input.
|
|
If no names are specified on the command line,
|
|
.Nm rdist
|
|
will update all of the files and directories listed in
|
|
.Ar 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 commands.
|
|
.Pp
|
|
Options specific to the second SYNOPSIS form:
|
|
.Pp
|
|
.Bl -tag -width Fl c
|
|
.It Fl c
|
|
Forces
|
|
.Nm rdist
|
|
to interpret the remaining arguments as a small
|
|
.Ar distfile .
|
|
.Pp
|
|
The equivalent distfile is as follows.
|
|
.Pp
|
|
.Bd -filled -offset indent -compact
|
|
.Pq Ar name ...
|

|
|
.Op Ar dest ;
|

.Ed
|
|

|
|
.El
|
|
.Pp
|
|
Options common to both forms:
|
|
.Pp
|
|
.Bl -tag -width Ic
|
|
.It Fl P Ar rshcmd
|
|
Alternative program to provide
|
|
.Xr rsh 1 -like
|
|
transport to the remote server. It must provide a binary-transparent path
|
|
to the remote server, and must have a command argument syntax that is
|
|
compatable with
|
|
.Xr rsh 1 .
|
|
.It Fl d Ar var=value
|
|
Define
|
|
.Ar var
|
|
to have
|
|
.Ar value .
|
|
The
|
|
.Fl d
|
|
option is used to define or override variable definitions in the
|
|
.Ar distfile .
|
|
.Ar Value
|
|
can be the empty string, one name, or a list of names surrounded by
|
|
parentheses and separated by tabs and/or spaces.
|
|
.It Fl h
|
|
Follow symbolic links. Copy the file that the link points to rather than the
|
|
link itself.
|
|
.It Fl i
|
|
Ignore unresolved links.
|
|
.Nm Rdist
|
|
will normally try to maintain the link structure of files being transferred
|
|
and warn the user if all the links cannot be found.
|
|
.It Fl m Ar host
|
|
Limit which machines are to be updated. Multiple
|
|
.Fl m
|
|
arguments can be given to limit updates to a subset of the hosts listed in the
|
|
.Ar distfile .
|
|
.It Fl n
|
|
Print the commands without executing them. This option is
|
|
useful for debugging
|
|
.Ar distfile .
|
|
.It Fl q
|
|
Quiet mode. Files that are being modified are normally
|
|
printed on standard output. The
|
|
.Fl q
|
|
option suppresses this.
|
|
.It Fl 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.
|
|
.It Fl 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.
|
|
.It Fl 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 ( dir1/f1 dir2/f2 ) to dir3 would create
|
|
files dir3/dir1/f1 and dir3/dir2/f2 instead of dir3/f1 and dir3/f2.
|
|
.It Fl y
|
|
Younger mode. Files are normally updated if their
|
|
.Ar mtime
|
|
and
|
|
.Ar size
|
|
(see
|
|
.Xr stat 2 )
|
|
disagree. The
|
|
.Fl y
|
|
option causes
|
|
.Nm rdist
|
|
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.
|
|
.El
|
|
.Pp
|
|
.Ar 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.
|
|
.Pp
|
|
.Bd -literal -offset indent -compact
|
|
<variable name> `=' <name list>
|
|
[label:]<source list> `\->' <destination list> <command list>
|
|
[label:]<source list> `::' <time_stamp file> <command list>
|
|
.Ed
|
|
.Pp
|
|
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
|
|
.Ar 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
|
|
.Ar 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 format).
|
|
.Pp
|
|
Labels are optional. They are used to identify a command for partial updates.
|
|
.Pp
|
|
Newlines, tabs, and blanks are only used as separators and are
|
|
otherwise ignored. Comments begin with `#' and end with a newline.
|
|
.Pp
|
|
Variables to be expanded begin with `$' followed by one character or
|
|
a name enclosed in curly braces (see the examples at the end).
|
|
.Pp
|
|
The source and destination lists have the following format:
|
|
.Bd -literal -offset indent
|
|
<name>
|
|
.Ed
|
|
or
|
|
.Bd -literal -offset indent -compact
|
|
`(' <zero or more names separated by white-space> `)'
|
|
.Ed
|
|
.Pp
|
|
The shell meta-characters `[', `]', `{', `}', `*', and `?'
|
|
are recognized and expanded (on the local host only) in the same way as
|
|
.Xr csh 1 .
|
|
They can be escaped with a backslash.
|
|
The `~' character is also expanded in the same way as
|
|
.Xr csh 1
|
|
but is expanded separately on the local and destination hosts.
|
|
When the
|
|
.Fl 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.
|
|
.Pp
|
|
The command list consists of zero or more commands of the following
|
|
format.
|
|
.Bd -ragged -offset indent -compact
|
|
.Bl -column except_patx pattern\ listx
|
|
.It `install' <options> opt_dest_name `;'
|
|
.It `notify' <name list> `;'
|
|
.It `except' <name list> `;'
|
|
.It `except_pat' <pattern list> `;'
|
|
.It `special' <name list> string `;'
|
|
.El
|
|
.Ed
|
|
.Pp
|
|
The
|
|
.Ic install
|
|
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.
|
|
.Ar Opt_dest_name
|
|
is an optional parameter to rename files.
|
|
If no
|
|
.Ic 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 corresponding filename is completely absent on the master host.
|
|
The
|
|
.Ar 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".
|
|
.Pp
|
|
The
|
|
.Ic 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, ...).
|
|
.Pp
|
|
The
|
|
.Ic except
|
|
command is used to update all of the files in the source list
|
|
.Ic except
|
|
for the files listed in
|
|
.Ar name list .
|
|
This is usually used to copy everything in a directory except certain files.
|
|
.Pp
|
|
The
|
|
.Ic except_pat
|
|
command is like the
|
|
.Ic except
|
|
command except that
|
|
.Ar pattern list
|
|
is a list of regular expressions
|
|
(see
|
|
.Xr re_format 7
|
|
for details).
|
|
If one of the patterns matches some string within a file name, that file will
|
|
be ignored.
|
|
Note that since `\e' is a quote character, it must be doubled to become
|
|
part of the regular expression. Variables are expanded in
|
|
.Ar pattern list
|
|
but not shell file pattern matching characters. To include a `$', it
|
|
must be escaped with `\e'.
|
|
.Pp
|
|
The
|
|
.Ic special
|
|
command is used to specify
|
|
.Xr sh 1
|
|
commands that are to be executed on the
|
|
remote host after the file in
|
|
.Ar name list
|
|
is updated or installed.
|
|
If the
|
|
.Ar 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
|
|
.Ar string .
|
|
.Ar String
|
|
starts and ends with `"' and can cross multiple lines in
|
|
.Ar 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
|
|
.Ar special
|
|
command can be used to rebuild private databases, etc.
|
|
after a program has been updated.
|
|

.Sh HISTORY
|
|
The

.Nm rdist
|
|
command appeared in
|
|
.Bx 4.3 .
|
|
.Sh DIAGNOSTICS
|
|
A complaint about mismatch of rdist version numbers may really stem
|
|
from some problem with starting your shell, e.g., you are in too many groups.
|
|
.Sh BUGS
|
|
Source files must reside on the local host where
|
|
.Nm rdist
|
|
is executed.
|
|
.Pp
|
|
There is no easy way to have a special command executed after all files
|
|
in a directory have been updated.
|
|
.Pp
|
|
Variable expansion only works for name lists; there should be a general macro
|
|
facility.
|
|
.Pp
|
|
.Nm Rdist
|
|
aborts on files which have a negative mtime (before Jan 1, 1970).
|
|
.Pp
|
|
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.
