JSM(1) General Commands Manual JSM(1)
NAME
jsm - send a command and read a reply
SYNOPSIS
jsm [ -V | --version ] [ -v | --verbose | -d level | --debug=level ] [
-h | --help ] [ -p | --paths ] [ -n | --simulate ] var=val ...
DESCRIPTION
Jsm is used by jsc(1), jsq(1), and jss(1) to send commands to jsd(1)
and read its replies. It is not expected that users call jsm directly.
Commands and replies consist of a sequence of one or more var=val
pairs. The exact format of such commands and replies depends on the
recipient and the precise nature of the command being sent.
CONFIGURATION
None.
OPTIONS
-d level, --debug=level Determines how verbose this program will be.
The message types displayed for the different
values of level are as follows: 0 displays no
messages; 1 displays only errors, 2 displays
errors and warnings; 3 displays errors, warn-
ings and informational messages; higher values
display errors, warnings, informational mes-
sages and various messages intended for debug-
ging. The default is 2.
-h, --help Displays a brief usage message.
-p, --paths Lists the compiled-in paths of various files
and directories that this program uses. -n,
--simulate Some external commands that this
program runs may be displayed rather than ac-
tually executed. BEWARE: different programs
implement different levels of simulation; so
this option may work perfectly; on the other
hand it may do nothing at all!
-v, --verbose Equivalent to -d 3.
-V, --version Prints the program's version number and exits.
EXIT STATUS
On success jsm returns zero. On failure it returns non-zero and dis-
plays a diagnostic message.
FILES
None.
ENVIRONMENT VARIABLES
JS_NAME or LOGNAME If JS_NAME is set then it is used to set the
name of the instance of jsd(1) with which to
communicate. If that is not set then LOGNAME
is used instead. If that is also not set then
an error occurs.
EXAMPLES
None.
CAVEATS
None.
