You can use "sed" to edit the file, you do not have to do it manually. To distribute the command you have several options, but none of them "out of the box", without having to set up the procedure:

1) Use ssh-keys to establish passwordless root-login between certain servers (usually one centralized admin-server which is allowed to connect to any other servers). Then use a simple loop to remote-execute the command on a list of servers. This is about as close to the "distributed shell" from the PSSP/Cluster1600 middleware suites as it gets.

2) If you have a centralized HMC you could use this to execute commands as "root" on a list of LPARs.

3) Some centralized monitoring software (for instance HP/OpenView) run local agents on every machine monitored which can be used as a vehicle to execute arbitrary scripts.

I hope this helps.

viewsudo

VIEW-OS(1)						      General Commands Manual							VIEW-OS(1)

NAME

       viewsudo - execute a command as another (virtual) user

SYNOPSIS

       viewsudo [-g groupname|#gid] [-u username|#uid] command

DESCRIPTION

       viewsudo allows a user to execute a command as the superuser or
	      another user in View-OS.

OPTIONS

       viewsudo accepts the following command line options:

       -g group
	   Normally,  viewsudo	sets the primary group to root.  The -g option causes sudo to run the specified command with the primary group set
	   to group.  To specify a gid instead of a group name, use #gid.  When running commands as a gid, many shells require	that  the  '#'	be
	   escaped  with  a  backslash	('[u2019]).   If  no -u option is specified, the command will be run as the invoking user (not root).	In
	   either case, the primary group will be set to group.

       -u user
	   The -u option causes viewsudo to run the specified command as a user other than root.  To specify a uid instead of  a  user	name,  use
	   #uid.  When running commands as a uid, many shells require that the '#' be escaped with a backslash ('[u2019]).

RETURN VALUES

       Upon successful execution of a program, the exit status from viewsudo will simply be the exit status of the program that was executed.
