Auto input to fetch cluster manager details

Team,

Presently i am trying to do basic checks on my my-sql cluster boxes.
The command ndb_mgm checks for the cluster environment details by typing the show command, and exit to come out of the ndb_mgm command.
Rather, than typing i have made a script abc.sh with the below contents in the below details

Code:

more abc.sh
/opt/app/abc/mysql/bin/ndb_mgm < <(yes show)

Here, once i run the script, the above command goes into iteration, and the details of show are shown on the screen in a continuous process,
(i.e:the same data is shown repetedly).Hence i just want to show it once on the screen and do the exit in-order for me to come out of the ndb_mgm command
Can anyone advise me ?

Regards
Whizkid

cmhaltcl

cmhaltcl(1m)															      cmhaltcl(1m)

NAME

       cmhaltcl - halt a high availability cluster

SYNOPSIS

       cmhaltcl [-f] [-v]

DESCRIPTION

       cmhaltcl  causes  all  nodes  in a configured cluster to stop their cluster daemons, optionally halting all packages or applications in the
       process.

       To stop a cluster, a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN  allowed  in  the  cluster  configuration
       file. See access policy in cmquerycl(1).

       This  command  will  halt  all  the  daemons on all currently running systems.  If the user only wants to shutdown a subset of daemons, the
       cmhaltnode command should be used instead.

   Options
       cmhaltcl supports the following options:

	      -f   Force the cluster to shutdown even if packages or group members are currently running.  This will cause the packages and  group
		   members to be halted.  If a package halt fails, the cluster halt will also fail.

	      -v   Verbose output will be displayed.

RETURN VALUE

       cmhaltcl returns the following value:

	       0   Successful completion.
	       1   Command failed.

EXAMPLES

       Halt the cluster daemons:

	      cmhaltcl
