RDYM (READY_MESSAGE) -- Set system ready message.
usage: rdym {-on | -off}
FORMAT
RDYM {-ON | -OFF}
RDYM enables or inhibits the output of a system ready message to
standard output after execution of each Shell command. The message
lists the CPU time required to execute the command and the elapsed
time since the last command. Both times are reported in seconds and
decimal fractions of seconds. The message appears on a line following
the echoed command line in the Shell's process transcript pad.
Turning on the ready message interactively causes it to be printed
after each line of input is processed. This means that if a
line contains several commands, or invokes a Shell script,
only one ready message will be printed.
Turning on the ready message in a Shell script causes it to be
printed after each command of the program is executed. If the
ready message is not disabled at the end of the Shell script,
it will remain in effect after the Shell script exits.
Ready message printing is enabled and disabled for LEVELS. The level
number increases each time a Shell script or the Shell is invoked,
and decreases when it exits. The times printed in the ready message
reflect the CPU and real time used since the last message at the same
level. Thus, for example, if the ready message is enabled in a Shell
script, after the last command of the program is finished, two (2)
ready messages will be printed: one showing the time used by that
command, and one showing the time used by the whole Shell script.
If the ready message is turned on by one level, it will remain on
when that level exits; however, if it is disabled by a level, it
will revert to its previous state when that level exits.
By default, system ready messages are disabled at log in.
OPTIONS
-ON Enable message.
-OFF Disable message.
