It preserves the owner, group, mode, and mtime of files if possible and can update programs that are executing. -.Nm Rdist +.I Rdist reads commands from -.Ar distfile +.I 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. +.I distfile +is `\-', the standard input is used. +If no +.B \-f +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, -.Nm rdist +.I rdist will update all of the files and directories listed in -.Ar distfile . +.IR 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.

Each file in the source list is added to a list of changes if the file is out of date on the host which is being updated (second format) or the file is newer than the time stamp file (third format).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 +.PP Labels are optional. They are used to identify a command for partial updates. -.Pp +.PP Newlines, tabs, and blanks are only used as separators and are otherwise ignored. Comments begin with `#' and end with a newline. -.Pp +.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 +.PP The source and destination lists have the following format: -.Bd -literal -offset indent +.nf + +.ti +.5i -.Ed or -.Bd -literal -offset indent -compact +.ti +.5i `(' `)' -.Ed -.Pp + +.fi +These simple lists can be modified by using one level of set addition, +subtraction, or intersection like this: +.nf + +.ti +.5i +list '-' list +or +.ti +.5i +list '+' list +or +.ti +.5i +list '&' list + +.fi +If additional modifications are needed (e.g., ``all servers and client +machines except for the OSF/1 machines'') then the list will have +to be explicitly constructed in steps using "temporary" variables. +.PP The shell meta-characters `[', `]', `{', `}', `*', and `?' are recognized and expanded (on the local host only) in the same way as -.Xr csh 1 . +.IR csh (1). They can be escaped with a backslash. The `~' character is also expanded in the same way as -.Xr csh 1 +.IR csh but is expanded separately on the local and destination hosts. When the -.Fl w +.B \-o\fIwhole\fR 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 +.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' opt_dest_name `;' -.It `notify' `;' -.It `except' `;' -.It `except_pat' `;' -.It `special' string `;' -.El -.Ed -.Pp +.nf + +.RS +.ta \w'cmdspecial 'u +\w'name list 'u +`install' opt_dest_name `;' +`notify' `;' +`except' `;' +`except_pat' `;' +`special' string `;' +`cmdspecial' string `;' +.RE + +.fi +.PP The -.Ic install +.I 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 +.I Opt_dest_name is an optional parameter to rename files. If no -.Ic install +.I 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.

If no `@' appears in the name, the destination host is appended to the name (e.g., name1@host, name2@host, ...). -.Pp +.PP The -.Ic except +.I except command is used to update all of the files in the source list -.Ic except -for the files listed in -.Ar name list . +.B except +for the files listed in \fIname list\fP.

Variables are expanded in -.Ar pattern list +part of the regular expression. Variables are expanded in \fIpattern list\fP but not shell file pattern matching characters. To include a `$', it must be escaped with `\e'. -.Pp +.PP The -.Ic special +.I special command is used to specify -.Xr sh 1 +.IR 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.

Multiple commands to the shell should be separated by `;'. Commands are executed in the user's home directory on the host being updated.
