Executing a command in subshell

Hi All,

I am trying to create a shell script which runs on my linux machine.

The requirement is so that,
Code:
ade createview xyz -> this steps creates a view
ade useview xyz -> we are entering inside the view
ade begintrans -> begin a transaction

My script has following code :

lets say my view name is xyz

Code:
n=`ade createview xyz`
n=`ade useview xyz`
n=`ade begintrans`

When I run these commands separately in my system, everything works fine but while trying to run these commands via shell script, the
ade createview xyz

command is successful but it stucks at the second command. I read something about subshells and pipelines, and since the 3rd command must run after the 2nd command I tried the parenthesis and |, it doesnt work.

FYI, the second command changes the directory structure, inside from which only 3rd command can be run.

Please suggest that how do I make sure that the 2nd command changes the directory structure and in side which only 3rd command is run..

Also is there any way user can also see the output these commands prints while I run them separately directly on terminal.

Thanks in adv..
Dish

nisserver(1M)						  System Administration Commands					     nisserver(1M)

NAME
nisserver - set up NIS+ servers SYNOPSIS
/usr/lib/nis/nisserver -r [-x] [-f] [-v] [-Y] [ -d NIS+_domain] [ -g NIS+_groupname] [-l network_passwd] /usr/lib/nis/nisserver -M [-x] [-f] [-v] [-Y] -d NIS+_domain [ -g NIS+_groupname] [ -h NIS+_server_host] /usr/lib/nis/nisserver -R [-x] [-f] [-v] [-Y] [ -d NIS+_domain] [ -h NIS+_server_host] DESCRIPTION
The nisserver shell script can be used to set up a root master, non-root master, and replica NIS+ server with level 2 security (DES). If other authentication mechanisms are configured with nisauthconf(1M), nisserver will set up a NIS+ server using those mechanisms. nisauth- conf(1M) should be used before nisserver. When setting up a new domain, this script creates the NIS+ directories (including groups_dir and org_dir) and system table objects for the domain specified. It does not populate the tables. nispopulate(1M) must be used to populate the tables. OPTIONS
-d NIS+_domain Specifies the name for the NIS+ domain. The default is your local domain. -f Forces the NIS+ server setup without prompting for confirmation. -g NIS+_groupname Specifies the NIS+ group name for the new domain. This option is not valid with -R option. The default group is admin.<domain>. -h NIS+_server_host Specifies the hostname for the NIS+ server. It must be a valid host in the local domain. Use a fully qualified hostname (for example, hostx.xyz.sun.com.) to specify a host outside of your local domain. This option is only used for setting up non-root master or replica servers. The default for non-root master server setup is to use the same list of servers as the parent domain. The default for replica server setup is the local hostname. -l network_password Specifies the network password with which to create the credentials for the root master server. This option is only used for master root server setup (-r option). If this option is not specified, the script prompts you for the login password. -M Sets up the specified host as a master server. Make sure that rpc.nisd(1M) is running on the new master server before this command is executed. -R Sets up the specified host as a replica server. Make sure that rpc.nisd is running on the new replica server. -r Sets up the server as a root master server. Use the -R option to set up a root replica server. -v Runs the script in verbose mode. -x Turns the echo mode on. The script just prints the commands that it would have executed. Note that the commands are not actually executed. The default is off. -Y Sets up a NIS+ server with NIS-compatibility mode. The default is to set up the server without NIS-compatibility mode. USAGE
Use the first synopsis of the command (-r) to set up a root master server. To run the command, you must be logged in as super-user on the server machine. Use the second synopsis of the command (-M) to set up a non-root master server for the specified domain. To run the command, you must be logged in as a NIS+ principal on a NIS+ machine and have write permission to the parent directory of the domain that you are setting up. The new non-root master server machine must already be an NIS+ client (see nisclient(1M)) and have the rpc.nisd(1M) daemon running. Use the third synopsis of the command (-R) to set up a replica server for both root and non-root domains. To run the command, you must be logged in as a NIS+ principal on a NIS+ machine and have write permission to the parent directory of the domain that you are replicating. The new non-root replica server machine must already be an NIS+ client and have the rpc.nisd daemon running. EXAMPLES
Example 1: Setting up Servers To set up a root master server for domain sun.com.: root_server# /usr/lib/nis/nisserver -r -d sun.com. For the following examples make sure that the new servers are NIS+ clients and that rpc.nisd is running on these hosts before executing nisserver. To set up a replica server for the sun.com. domain on host sunreplica: root_server# /usr/lib/nis/nisserver -R -d sun.com. -h sunrep To set up a non-root master server for domain xyz.sun.com. on host sunxyz with the NIS+ groupname as admin-mgr.xyz.sun.com.: root_server# /usr/lib/nis/nisserver -M -d xyz.sun.com. -h sunxyz -g admin-mgr.xyz.sun.com. To set up a non-root replica server for domain xyz.sun.com. on host sunabc: sunxyz# /usr/lib/nis/nisserver -R -d xyz.sun.com. -h sunabc ATTRIBUTES
