Using rdist
Creating the Distfile
If there is no install command in a distfile or if the destpath option is
not used with the install command, the name of the file on the master
host is given to the remote host’s file. Parent directories in a file’s path
are created on a remote host if they do not exist. rdist does not replace
non-empty directories on a remote host. However, if the -R option is
specified with the install command, a non-empty directory is removed
on the remote host if the corresponding directory does not exist on the
master host.
For a detailed description of commands and their options, type
man 1 rdist at the HP-UX prompt.
The following two examples of file distribution commands use the
variable definitions that were shown previously:
${FILES} -> ${HOSTS}
install -R ;
except /usr/lib/${EXLIB} ;
except /usr/games/lib ;
srcs:
/usr/src/bin -> arpa
except_pat ( \\.o$ /SCCS\$ ) ;
The first example distributes the source files defined in the variable
FILES to the destination hosts defined in the variable HOSTS. rdist
copies the files to each remote host, removing files in the remote host’s
directory that do not exist on the master directory. rdist does notupdate
files in /usr/lib/${EXLIB} or in /usr/games/lib.
The second example (labeled srcs) distributes the directory
/usr/src/bin to the host arpa; object files or files that are under SCCS
control are not copied.
special [ file ] ” command ” Specifies command(s) that are to be executed on the remote host
after each specified file is updated or installed. Used to rebuild
databases and configuration files after a program has been
updated. If file is not specified, command is performed for
every updated file. command can contain multiple commands,
each separated by semicolons. The user’s home directory on the
remote host is the default working directory for each command.
