Alas, there is no such general setting. In fact "set -x" is not only reset for every child script but also when entering a subfunction in script. This default makes sense, because in most cases you do not want diagnostic output at all and whenever you request it explicitly (by issuing "set -x") you probably want to test only the one script (part) you set it, not everything else.

For the functionality you want i usually add the following line at a sensible place in every script:

Code:
#! /bin/ksh

[...] some introducory statements uninteresting for debugging

$chFullDebug

[...] more statements, interesting for diagnostic output

Under normal circumstances the shell variable "chFullDebug" is set to "" and the statement is silently ignored. If i need full debugging, though, i set it like this:

Code:
chFullDebug="set -xv" ; export chFullDebug

and from then on "set -xv" is issued in every script/function. because of the "export" keyword every subsequently opened environment inherits this setting.

Alternatively you could add "-xv" as option to the shebang line:

Code:
#! /bin/ksh -xv

[...] commands

If all the scripts you want to behave this way are in a certain place let a sed-script do the work for you. Put the following into a loop and feed it the list of scipt names you want to be changed:

Code:
sed '1 s/ksh/& -xv/g' /path/to/script.sh > /path/to/script.sh.debug

(Replace "ksh" with whatever shell you are using if needed.)

I hope this helps.

cmhaltserv

cmhaltserv(1m)															    cmhaltserv(1m)

NAME

       cmhaltserv - halt a service from the high availability package halt script

SYNOPSIS

       cmhaltserv [-v] service_name

DESCRIPTION

       cmhaltserv is used only in the high availability package halt script to halt a service.

       To  stop  a  package  service,  the  running  package  halt  script must be running as superuser(UID=0), or as a user with access policy of
       FULL_ADMIN allowed in the cluster configuration file. See access policy in cmquerycl(1) or cmmakepkg(1).

       If any part of a package is marked down, the package halt script is executed as part of the recovery process.

       This command sends a SIGTERM signal to the PID and the corresponding process group of the monitored service.  If this signal is	caught	by
       the running application, it is up to the application to ensure that the processes will be terminated.

   Options
       cmhaltserv supports the following options:

	      -v   Verbose output will be displayed.

RETURN VALUE

       cmhaltserv returns the following values:

	       0   Successful completion.
	       1   Command failed.

EXAMPLES

       To halt the service db1, do the following:

	      # Halt the service db1
	      cmhaltserv db1

       This line should only be executed within a package halt script.

AUTHOR

       cmhaltserv was developed by HP.
