E-73 CommKit Host Interface, Release 4.0
NAME
dkdotab – transparent remote command control file
DESCRIPTION
This file is used by the dkdo(1C) program to obtain information on where and how to process commands. The
default file is /etc/opt/dk/dkdotab.
dkdotab consists of one or more lines, each with exactly five fields. Each time a command emulation is
processed by dkdo(1C), it scans this file for the first match with the command requested. If a match is found,
the remaining fields indicate on which host the command is to be executed, what flags affect the operation of
dkdo(1C), what option letters are applicable for execution of the desired command, and whether the files
associated with this command are input, output, or a combination of both. If a field in the dkdotab is not
applicable for a given command, a – must be specified in place of the field.
The field that participates in the match is the Command field. If the call fails to one host, the table is scanned
for the next match and the calling process repeated.
The lines consist of the following fields delimited by tabs and/or blanks.
Command: Command to be executed on a remote host. This field length is not to exceed 16 characters.
System: System on which the command is to be executed. This field length is not to exceed 64
characters.
Flags: Zero or more of the flags s or x. This field length is not to exceed 32 characters.
s If the filenames are preceded by an s., as with SCCS files, the file without the s. is
sent.
x Use .rx instead of .do as the service class. Requesting the ’.rx’ service on the
remote system causes the user’s .profile on that system to be executed prior to the
remote command.
Options: Zero or more options may be specified for a given command. The options correspond to the
various command-specific options supported by dkdo(1C). This field length is not to
exceed 128 characters. The various options are delimited by four possible operators:
: Arguments that follow the option flag are arguments associated with that option.
The arguments may or may not follow directly after the option specification.
~ Only arguments that directly follow the option flag are associated with that option.
< Arguments that follow are input files.
> Arguments that follow are output files.
Files: Description of the type of files that follow the options associated with this command. This
field length is not to exceed 16 characters.
> Output file
< Input file
* The preceding file indicator applies to all remaining files associated with this
command.
: Preceded by a flag. Insert the indicated flag in the command line before it is
invoked.
