Exit Status within sudo su - $user
I am having a problem reading the exit status of a command or script within a sudo.


Code:
return_code=99

sudo su - $User << EOF >> $output_file
$Script
return_code=$? 
exit $return_code
EOF

echo "return_code=$return_code"

returns
"return_code=99"

the $script above is a test script with a "exit 5" at the end. When I run it as the user and echo $? I get a 5.

I have been scanning the forums, trying my own stuff too, but cant seem to find the answer. How do I get the return code from the script (or command) passed out?

Thanks if you can help.

LEARN ABOUT LINUX

s390_sthyi

S390_STHYI(2)							System Calls Manual						     S390_STHYI(2)

NAME

       s390_sthyi - emulate STHYI instruction

SYNOPSIS

       #include <asm/unistd.h>

       int s390_sthyi(unsigned long function_code, void *resp_buffer,
		      uint64_t *return_code, unsigned long flags);

DESCRIPTION

       The  s390_sthyi() system call emulates the STHYI (Store Hypervisor Information) instruction.  It provides hardware resource information for
       the machine and its virtualization levels.  This includes CPU type and capacity, as well as the machine model and other metrics.

       The function_code argument indicates which function to perform.	The following code(s) are supported:

       0      Return CP (Central Processor) and IFL (Integrated Facility for Linux) capacity information.

       The resp_buffer argument specifies the address of a response buffer.  When the function_code is 0, the buffer must  be  one  page  (4K)	in
       size.   If  the	system call returns 0, the response buffer will be filled with CPU capacity information.  Otherwise, the response buffer's
       content is unchanged.

       The return_code argument stores the return code of the STHYI instruction, using one of the following values:

       0       Success.

       4       Unsupported function code.

       For further details about return_code, function_code, and resp_buffer, see the reference given in NOTES.

       The flags argument is provided to allow for future extensions and currently must be set to 0.

RETURN VALUE

       On success (that is: emulation succeeded), the return value of s390_sthyi() matches the condition code of the STHYI instructions, which	is
       a  value  in the range [0..3].  A return value of 0 indicates that CPU capacity information is stored in *resp_buffer.  A return value of 3
       indicates "unsupported function code" and the content of *resp_buffer is unchanged.  The return values 1 and 2 are reserved.

       On error, -1 is returned, and errno is set appropriately.

ERRORS

       EFAULT The value specified in resp_buffer or return_code is not a valid address.

       EINVAL The value specified in flags is nonzero.

       ENOMEM Allocating memory for handling the CPU capacity information failed.

       EOPNOTSUPP
	      The value specified in function_code is not valid.

VERSIONS

       This system call is available since Linux 4.15.

CONFORMING TO

       This Linux-specific system call is available only on the s390 architecture.

NOTES

       Glibc does not provide a wrapper for this system call, use syscall(2) to call it.

       For  details  of  the   STHYI   instruction,   see   the   documentation   page	 <https://www.ibm.com/support/knowledgecenter/SSB27U_6.3.0
       /com.ibm.zvm.v630.hcpb4/hcpb4sth.htm>.

       When  the system call interface is used, the response buffer doesn't have to fulfill alignment requirements described in the STHYI instruc-
       tion definition.

       The kernel caches the response (for up to one second, as of Linux  4.16).   Subsequent  system  call  invocations  may  return  the  cached
       response.
