Issue running script as root

1) Environment:Red Hat Linux, bash shell

Script to be run owned by user :myUser
Home environment of myUser: pathto/home

2) ESP agent with root access will run

JobXXX.sh
su - myUser -c "/pathto/home/bin/script.sh"
where script.sh has some echo statements and an exit statement in the end


Current behaviour when running the script:
root@ServerName1>./JobXXX.sh

(and then the control remains on the following path)
myUser@Servername1[pathto/home]
(have to print "exit" to get the output of echo statements and ctrl back to root@ServerName1


Expected behaviour when running the script:
root@ServerName1>./JobXXX.sh
  • Runs /pathto/home/bin/script.sh
  • Prints the echo statements
  • ctrl is root@ServerName1

Any suggestions how to fix the issue ?

Thanks for help.

RBASH(1)						      General Commands Manual							  RBASH(1)

NAME
rbash - restricted bash, see bash(1) RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow- ing are disallowed or not performed: o changing directories with cd o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV o specifying command names containing / o specifying a file name containing a / as an argument to the . builtin command o specifying a filename containing a slash as an argument to the -p option to the hash builtin command o importing function definitions from the shell environment at startup o parsing the value of SHELLOPTS from the shell environment at startup o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators o using the exec builtin command to replace the shell with another command o adding or deleting builtin commands with the -f and -d options to the enable builtin command o using the enable builtin command to enable disabled shell builtins o specifying the -p option to the command builtin command o turning off restricted mode with set +r or set +o restricted. These restrictions are enforced after any startup files are read. When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script. SEE ALSO
