1.14 millert 61: .Sh DESCRIPTION
62: .Nm
1.8 aaron 63: is a program to maintain identical copies of files over multiple hosts.
1.1 deraadt 64: It preserves the owner, group, mode, and mtime of files if possible and
65: can update programs that are executing.
1.14 millert 66: .Nm
1.1 deraadt 67: reads commands from
1.14 millert 68: .Pa distfile
1.1 deraadt 69: to direct the updating of files and/or directories.
70: If
1.14 millert 71: .Pa distfile
72: is
73: .Sq - ,
74: the standard input is used.
1.2 dm 75: If no
1.14 millert 76: .Fl f
77: option is present, the program looks first for
78: .Pa distfile ,
79: then
1.25 jmc 80: .Pa Distfile ,
1.14 millert 81: to use as the input.
1.1 deraadt 82: If no names are specified on the command line,
1.14 millert 83: .Nm
1.1 deraadt 84: will update all of the files and directories listed in
1.14 millert 85: .Pa distfile .
1.1 deraadt 86: Otherwise, the argument is taken to be the name of a file to be updated
1.14 millert 87: or the label of a command to execute.
88: If label and file names conflict, it is assumed to be a label.
89: These may be used together to update specific files using specific commands.
90: .Pp
91: .Nm
1.13 millert 92: uses a remote shell command to access each target host.
93: By default,
1.14 millert 94: .Xr ssh 1
1.25 jmc 95: is used unless overridden by the
1.14 millert 96: .Fl P
97: option or the
98: .Ev RSH
99: environment variable.
1.13 millert 100: If the target host is the string
1.25 jmc 101: .Dq localhost
1.14 millert 102: and the remote user name is the same as the local user name,
103: .Nm
1.24 jmc 104: will run the command:
1.14 millert 105: .Bd -literal -offset indent
106: /bin/sh -c rdistd -S
107: .Ed
108: .Pp
109: Otherwise,
110: .Nm
1.24 jmc 111: run will run the command:
1.14 millert 112: .Bd -literal -offset indent
1.25 jmc 113: ssh \*(Lthost\*(Gt -l \*(Ltlogin_name\*(Gt rdistd -S
1.14 millert 114: .Ed
115: .Pp
1.25 jmc 116: .Ar host
117: is the name of the target host;
118: .Ar login_name
119: is the name of the user to make the connection as.
1.14 millert 120: .Pp
1.2 dm 121: On each target host
1.14 millert 122: .Nm
1.25 jmc 123: will attempt to run the command:
1.14 millert 124: .Bd -literal -offset indent
125: rdistd -S
126: .Ed
1.25 jmc 127: .Pp
128: Or if the
129: .Fl p
130: option was specified,
131: .Nm
132: will attempt to run the command:
133: .Bd -literal -offset indent
1.24 jmc 134: \*(Ltrdistd path\*(Gt -S
1.14 millert 135: .Ed
136: .Pp
1.2 dm 137: If no
1.14 millert 138: .Fl p
1.25 jmc 139: option is specified, or
1.24 jmc 140: .Aq Ar rdistd path
1.2 dm 141: is a simple filename,
1.24 jmc 142: .Xr rdistd 1
1.2 dm 143: or
1.24 jmc 144: .Aq Ar rdistd path
1.8 aaron 145: must be somewhere in the
1.14 millert 146: .Ev PATH
1.2 dm 147: of the user running
1.14 millert 148: .Nm
1.2 dm 149: on the remote (target) host.
1.14 millert 150: .Pp
151: The options are as follows:
152: .Bl -tag -width Ds
153: .It Fl A Ar num
1.2 dm 154: Set the minimum number of free files (inodes) on a filesystem that must exist
1.8 aaron 155: for

1.14 millert 158: .It Fl a Ar num
1.2 dm 159: Set the minimum amount of free space (in bytes) on a filesystem that must exist
1.8 aaron 160: for
1.14 millert 161: .Nm
1.2 dm 162: to update or install a file.
1.22 jmc 163: .It Fl c Ar mini_distfile
164: Forces
165: .Nm
1.27 jmc 166: to interpret the remaining arguments as a small distfile.
167: The format is:
168: .Bd -literal -offset indent
169: $ rdist -c name ... [login@]host[:dest]
170: .Ed
171: .Pp
172: The equivalent distfile is as follows:
1.22 jmc 173: .Bd -literal -offset indent
1.24 jmc 174: ( name ... ) -\*(Gt [login@]host
175: install [dest] ;
1.22 jmc 176: .Ed
1.14 millert 177: .It Fl D
1.2 dm 178: Enable copious debugging messages.
1.22 jmc 179: .It Xo
180: .Fl d Ar var Ns = Ns Ar value
181: .Xc
1.1 deraadt 182: Define
1.14 millert 183: .Ar var
1.1 deraadt 184: to have
1.14 millert 185: .Ar value .
1.2 dm 186: This
1.26 jmc 187: option is used to define or override variable definitions in
1.14 millert 188: .Pa distfile .
189: .Ar value
1.1 deraadt 190: can be the empty string, one name, or a list of names surrounded by
191: parentheses and separated by tabs and/or spaces.
1.14 millert 192: .It Fl F
1.8 aaron 193: Do not fork any child
1.14 millert 194: .Nm
1.2 dm 195: processes.
196: All clients are updated sequentially.
1.14 millert 197: .It Fl f Ar distfile
1.26 jmc 198: Set the name of the distfile to
1.14 millert 199: .Ar distfile .
1.8 aaron 200: If
1.26 jmc 201: .Sq -
202: (dash) is used then read from standard input (stdin).
1.22 jmc 203: .It Fl L Ar remote_logopts
204: Set remote logging options.
1.8 aaron 205: See the section
1.26 jmc 206: .Sx MESSAGE LOGGING
1.2 dm 207: for details on the syntax for
1.26 jmc 208: .Ar remote_logopts .
1.22 jmc 209: .It Fl l Ar local_logopts
210: Set local logging options.
1.8 aaron 211: See the section
1.26 jmc 212: .Sx MESSAGE LOGGING
1.2 dm 213: for details on the syntax for
1.26 jmc 214: .Ar local_logopts .
1.22 jmc 215: .It Fl M Ar maxproc
1.14 millert 216: Set the maximum number of simultaneously running child
217: .Nm
1.2 dm 218: processes to
1.22 jmc 219: .Ar maxproc .
1.2 dm 220: The default is 4.
1.22 jmc 221: .It Fl m Ar host
1.19 jmc 222: Limit which machines are to be updated.
223: Multiple
1.14 millert 224: .Fl m
1.26 jmc 225: arguments can be given to limit updates to a subset of the hosts listed in
1.14 millert 226: .Pa distfile .
227: .It Fl n
228: Print the commands without executing them.
1.26 jmc 229: This option is useful for debugging a distfile.
1.22 jmc 230: .It Fl o Ar distopts
1.2 dm 231: Specify the dist options to enable.
1.14 millert 232: .Ar distopts
1.2 dm 233: is a comma separated list of options which are listed below.
234: The valid values for
1.14 millert 235: .Ar distopts
1.2 dm 236: are:
1.14 millert 237: .Bl -tag -width Ds
1.22 jmc 238: .It Ic chknfs
1.26 jmc 239: Do not check or update files on the target host
240: that reside on NFS filesystems.
1.22 jmc 241: .It Ic chkreadonly
1.26 jmc 242: Enable a check on the target host
243: to see if a file resides on a read-only filesystem.
1.2 dm 244: If a file does, then no checking or updating of the file is attempted.
1.22 jmc 245: .It Ic chksym
1.2 dm 246: If the target on the remote host is a symbolic link, but is not on the
247: master host, the remote target will be left a symbolic link.
248: This behavior is generally considered a bug in the original version of
1.14 millert 249: .Nm rdist ,
1.2 dm 250: but is present to allow compatibility with older versions.
1.22 jmc 251: .It Ic compare
252: Binary comparison.
253: Perform a binary comparison and update files if they differ rather than
254: comparing dates and sizes.
255: .It Ic defgroup Ns Op = Ns Ic groupname
1.17 millert 256: If the group of a file to be transferred does not exist on the destination
257: host, use the specified group instead.
258: If groupname is not specified, the
259: .Em bin
260: group is used.
1.22 jmc 261: .It Ic defowner Ns Op = Ns Ic owner
1.17 millert 262: If the owner of a file to be transferred does not exist on the destination
263: host, use the specified owner instead.
264: If owner is not specified, the user
265: .Em bin
266: is used.
1.22 jmc 267: .It Ic follow
268: Follow symbolic links.
269: Copy the file that the link points to rather than the link itself.
270: .It Ic history
271: When
272: .Ic savetargets
273: and
274: .Ic history
275: are both defined then the target file that is updated is first renamed from
276: .Pa file
277: to
278: .Pa file.NNN
279: where NNN increases for each generation update.
280: The first generation is 001, and the last is 999.
1.29 ! jmc 281: After 999 generations, the counter is reset and stuck to 001,
! 282: and 001 will get overwritten all the time.
1.22 jmc 283: This is undesirable behavior, so some other method needs to be devised
284: to clean up or limit the number of generations.
285: .It Ic ignlnks
286: Ignore unresolved links.
287: .Nm
288: will normally try to maintain the link structure of files being transferred
289: and warn the user if all the links cannot be found.
290: .It Ic nochkgroup
1.2 dm 291: Do not check group ownership of files that already exist.
292: The file ownership is only set when the file is updated.
1.22 jmc 293: .It Ic nochkmode
1.2 dm 294: Do not check file and directory permission modes.
295: The permission mode is only set when the file is updated.
1.22 jmc 296: .It Ic nochkowner
297: Do not check user ownership of files that already exist.
298: The file ownership is only set when the file is updated.
299: .It Ic nodescend
1.2 dm 300: Do not descend into a directory.
1.14 millert 301: Normally,
302: .Nm
1.2 dm 303: will recursively check directories.
1.14 millert 304: If this option is enabled, then any files listed in the file list in the
305: distfile that are directories are not recursively scanned.
1.2 dm 306: Only the existence, ownership, and mode of the directory are checked.
1.22 jmc 307: .It Ic noexec
1.29 ! jmc 308: Automatically exclude executable binary files that are in
1.22 jmc 309: .Xr a.out 5
1.29 ! jmc 310: or
! 311: .Xr elf 5
1.22 jmc 312: format from being checked or updated.
313: .It Ic numchkgroup
1.9 aaron 314: Use the numeric group ID (GID) to check group ownership instead of
1.2 dm 315: the group name.
1.22 jmc 316: .It Ic numchkowner
1.9 aaron 317: Use the numeric user ID (UID) to check user ownership instead of
1.2 dm 318: the user name.
1.22 jmc 319: .It Ic quiet
320: Quiet mode.
321: Files that are being modified are normally printed on standard output.
322: This option suppresses that.
323: .It Ic remove
324: Remove extraneous files.
325: If a directory is being updated, any files that exist on the remote host
326: that do not exist in the master directory are removed.
327: This is useful for maintaining truly identical copies of directories.
328: .It Ic savetargets
1.2 dm 329: Save files that are updated instead of removing them.
1.15 deraadt 330: Any target file that is updated is first renamed from
1.14 millert 331: .Pa file
1.2 dm 332: to
1.14 millert 333: .Pa file.OLD .
1.22 jmc 334: .It Ic sparse
1.29 ! jmc 335: Enable checking for sparse files.
1.14 millert 336: One of the most common types of sparse files are those produced by
337: .Xr db 3 .
1.3 dm 338: This option adds some additional processing overhead so it should
339: only be enabled for targets likely to contain sparse files.
1.22 jmc 340: .It Ic updateperm
341: Do not send the whole file when the size and the modification time match.
342: Instead, just update the ownership, group, and permissions as necessary.
343: .It Ic verify
344: Verify that the files are up to date on all the hosts.
1.26 jmc 345: Any files that are out of date will be displayed
346: but no files will be changed and no mail will be sent.
1.22 jmc 347: .It Ic whole
348: Whole mode.
349: The whole file name is appended to the destination directory name.
350: Normally, only the last component of a name is used when renaming files.
351: This will preserve the directory structure of the files being
352: copied instead of flattening the directory structure.
353: For example, rdisting a list of files such as
1.26 jmc 354: .Pa /p/dir1/f1
1.22 jmc 355: and
1.26 jmc 356: .Pa /p/dir2/f2
1.22 jmc 357: to
358: .Pa /tmp/dir
359: would create files
1.26 jmc 360: .Pa /tmp/dir/p/dir1/f1
1.22 jmc 361: and
1.26 jmc 362: .Pa /tmp/dir/p/dir2/f2
1.22 jmc 363: instead of
364: .Pa /tmp/dir/dir1/f1
365: and
366: .Pa /tmp/dir/dir2/f2 .
367: .It Ic younger
368: Younger mode.
369: Files are normally updated if their
370: .Em mtime
371: and
372: .Em size
373: (see
374: .Xr stat 2 )
375: disagree.
376: This option causes
377: .Nm
378: not to update files that are younger than the master copy.
379: This can be used to prevent newer copies on other hosts from being replaced.
380: A warning message is printed for files which are newer than the master copy.
1.14 millert 381: .El
1.22 jmc 382: .It Fl P Ar rsh-path
1.14 millert 383: Set the path to the remote shell command.
1.21 jmc 384: .Ar rsh-path
1.7 deraadt 385: may be a colon separated list of possible pathnames.
1.2 dm 386: In this case, the first component of the path to exist is used.
1.24 jmc 387: For example,
1.26 jmc 388: .Pa /usr/bin/ssh:/usr/bin/rsh
389: or
1.14 millert 390: .Pa /usr/bin/ssh .
1.22 jmc 391: .It Fl p Ar rdistd-path
392: Set the path where the rdistd server is searched for on the target host.
393: .It Fl Server
394: This option is recognized to provide partial backward compatible support
395: for older versions of
396: .Nm
397: which used this option to put
398: .Nm
399: into server mode.
400: If
401: .Nm
402: is started with the
403: .Fl Server
404: command line option, it will attempt to exec (run) the old version of
405: .Nm rdist ,
406: .Pa /usr/bin/oldrdist .
1.14 millert 407: .It Fl t Ar timeout
1.26 jmc 408: Set the timeout period,
409: in seconds,
410: for waiting for responses from the remote
1.14 millert 411: .Nm
1.2 dm 412: server.
413: The default is 900 seconds.
1.14 millert 414: .It Fl V
1.2 dm 415: Print version information and exit.
1.16 jmc 416: .El
1.14 millert 417: .Sh DISTFILES
1.2 dm 418: The
1.14 millert 419: .Pa distfile
1.1 deraadt 420: contains a sequence of entries that specify the files
421: to be copied, the destination hosts, and what operations to perform
1.19 jmc 422: to do the updating.
423: Each entry has one of the following formats.
1.14 millert 424: .Bd -literal -offset indent
1.24 jmc 425: \*(Ltvariable name\*(Gt `=' \*(Ltname list\*(Gt
426: [ label: ] \*(Ltsource list\*(Gt `\-\*(Gt' \*(Ltdestination list\*(Gt \*(Ltcommand list\*(Gt

1.14 millert 428: .Ed
429: .Pp
1.1 deraadt 430: The first format is used for defining variables.
431: The second format is used for distributing files to other hosts.
432: The third format is used for making lists of files that have been changed
433: since some given date.
1.14 millert 434: The
435: .Em source list
436: specifies a list of files and/or directories on the local host which are to
437: be used as the master copy for distribution.
438: The
439: .Em destination list
440: is the list of hosts to which these files are to be copied.
441: Each file in the source list is added to a list of changes if the file
442: is out of date on the host which is being updated (second format) or
1.1 deraadt 443: the file is newer than the time stamp file (third format).
1.14 millert 444: .Pp
445: Labels are optional.
446: They are used to identify a command for partial updates.
447: .Pp
1.1 deraadt 448: Newlines, tabs, and blanks are only used as separators and are
1.14 millert 449: otherwise ignored.
450: Comments begin with
451: .Sq #
452: and end with a newline.
453: .Pp
454: Variables to be expanded begin with
455: .Sq $
456: followed by one character or a name enclosed in curly braces
457: (see the examples at the end).
458: .Pp
1.1 deraadt 459: The source and destination lists have the following format:
1.14 millert 460: .Bd -literal -offset indent
1.24 jmc 461: \*(Ltname\*(Gt
1.14 millert 462: .Ed
1.1 deraadt 463: or

1.24 jmc 465: `(' \*(Ltzero or more names separated by whitespace\*(Gt `)'
1.14 millert 466: .Ed
467: .Pp
1.2 dm 468: These simple lists can be modified by using one level of set addition,
469: subtraction, or intersection like this:
1.14 millert 470: .Bd -literal -offset indent
1.2 dm 471: list '-' list

1.1 deraadt 563: for details).
564: If one of the patterns matches some string within a file name, that file will

566: Note that since `\e' is a quote character, it must be doubled to become
1.14 millert 567: part of the regular expression.
568: Variables are expanded in
569: .Em pattern list
570: but not shell file pattern matching characters.
571: To include a `$', it must be escaped with `\e'.
572: .Pp
1.1 deraadt 573: The

1.2 dm 610: command, except it is executed only when the entire command is completed
611: instead of after each file is updated.
1.14 millert 612: The list of files is placed in the
