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,
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

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..

Not clear. Post the relevant portion of your script, and OS & shell versions.

# Function Declaration Start

echo -n "Enter Series Name : "
read series
echo -n "Bug Number : "
read bugNumber

n=`ade createview xyz -latest -series $series
n=`ade useview xyz`   ----> here is where my script is getting stuck
n=`ade begintrans bug\-$bugNumber`  ----> this command should run only after we are inside the view, which happens by running useview command successfully.


This is my script.
These command are ADE commands. Ref # http://docs.oracle.com/cd/A60725_05/...er/iw04c03.htm

I do not want you to go into much details but all I want to do is, retain the path which is achieved by useview command and then continue supplying the begintrans command. Apparently useview command internally starts a subshell, so my doubt is how do i run following command in the subshell created by previous command and retain the paths.

Hope I am clear.

Please let me know if I can clarify more.
