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.
