name Change the status of the layer referred to by name to that of current layer. Any unique
prefix is accepted.
WARNINGS
Commands
The behavior of the
block and unblock shl
commands is not guaranteed when the SHELL environ-
ment variable is set to
/usr/bin/csh (for csh (1)) or
/usr/bin/ksh (for ksh(1)), or when the shell
saves and restores the tty state (defined in termio (7)) before and after each command is invoked interac-
tively from that shell. For both
/usr/bin/csh and /usr/bin/ksh, the loblk or -loblk options of
stty can be used from within the layer to block or unblock the output of that layer.
Ptydaemon
For
shl to function properly, the
ptydaemon process must be running on the system. If your system
has been installed with the Desktop HP-UX product, then
ptydaemon will not be started by default. In
order to start this daemon, change
PTYDAEMON_START
from a "0" to a "1" in the
/etc/rc.config.d/ptydaemon
file. The system must either be rebooted for this change to take
effect, or you can manually start this daemon by typing :
/usr/sbin/ptydaemon
Note that ptydaemon will also be disabled if the DesktopConfig.LITECONFIG fileset has been installed
on the system, or if the system administrator has previously run the
SAM utility and selected the Apply
Lite HP-UX Configuration Action
from within any of SAM’s Kernel Configuration
screens.
shl does not support long user and group names on the current release, HP-UX 11i V3.
