Bug How to run cmds after changing to a new env (shell) in a shell script

Hi,

I am using HP-UNIX.

I have a requirement as below

I have to change env twice like:

cadenv <env>
cadenv <env>
ccm start -d /dbpath
ccm tar -xvf *.tar
ccm rcv ....
mv *.tar BACKUP

but after I do the first cadenv <env> , I am unable to execute any of the later commands .

I have tried using /bin/sh -c "cmd"

but it does not seem to work. I have not sepreated these cmds by ; though. They are still seperated by newline. they look as below:


cadenv <env>
cadenv <env>
/bin/sh -c "ccm start -d /dbpath"
/bin/sh -c "ccm tar -xvf *.tar"
/bin/sh -c "ccm rcv ...."
/bin/sh -c "mv *.tar BACKUP"

can someone please help?

thanks,
Charlei

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME
atf-sh [-s shell] -- interpreter for shell-based test programs SYNOPSIS
atf-sh script DESCRIPTION
atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library. atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL. atf-sh executes the inter- preter, loads the atf-sh(3) library and then runs the script. You must consider atf-sh to be a POSIX shell by default and thus should not use any non-standard extensions. The following options are available: -s shell Specifies the shell to use instead of the value provided by ATF_SHELL. ENVIRONMENT
ATF_LIBEXECDIR Overrides the builtin directory where atf-sh is located. Should not be overridden other than for testing purposes. ATF_PKGDATADIR Overrides the builtin directory where libatf-sh.subr is located. Should not be overridden other than for testing purposes. ATF_SHELL Path to the system shell to be used in the generated scripts. Scripts must not rely on this variable being set to select a specific interpreter. EXAMPLES
Scripts using atf-sh(3) should start with: #! /usr/bin/env atf-sh Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh. Instead, you have to hardcode the path to atf-sh in the script and then use the -s option afterwards as a single parameter: #! /path/to/bin/atf-sh -s/bin/bash ENVIRONMENT
ATF_SHELL Path to the system shell to be used in the generated scripts. SEE ALSO
atf-sh(3) BSD
