Current shell session hungs when run another binary
Hi,
I am on AIX 7.1 and when I try to login to my account and sudo to other generic account (mqm user) my ssh session just hungs.

==================
Code:
$ id
uid=16150(sxp) gid=179(rax) groups=1179(raxs)
$
$
$ sudo su - mqm
Password:

--------
Changed username to: mqm
--------
Code:
. /opt/IBM/mq8/usr/mqm/bin/setmqenv -p /opt/IBM/mq8

-- this works when executed manually.
==================

I need to include the above command (. /opt/IBM/mq8/usr/mqm/bin/setmqenv -p /opt/IBM/mq8) in .kshrc to avoid retyping every time when I log into mqm user.

When I include this command in .kshrc, my login session just hungs when I sudo to mqm user. I need to do a 'Ctrl + c' to come out.

Can you please advise how to avoid the hung session?.

chsh

CHSH(1) 							   User Commands							   CHSH(1)

NAME

       chsh - change login shell

SYNOPSIS

       chsh [options] [LOGIN]

DESCRIPTION

       The chsh command changes the user login shell. This determines the name of the user's initial login command. A normal user may only change
       the login shell for her own account; the superuser may change the login shell for any account.

OPTIONS

       The options which apply to the chsh command are:

       -h, --help
	   Display help message and exit.

       -R, --root CHROOT_DIR
	   Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory.

       -s, --shell SHELL
	   The name of the user's new login shell. Setting this field to blank causes the system to select the default login shell.

       If the -s option is not selected, chsh operates in an interactive fashion, prompting the user with the current login shell. Enter the new
       value to change the shell, or leave the line blank to use the current one. The current shell is displayed between a pair of [ ] marks.

NOTE

       The only restriction placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker is the superuser,
       and then any value may be added. An account with a restricted login shell may not change her login shell. For this reason, placing /bin/rsh
       in /etc/shells is discouraged since accidentally changing to a restricted shell would prevent the user from ever changing her login shell
       back to its original value.

FILES

       /etc/passwd
	   User account information.

       /etc/shells
	   List of valid login shells.

       /etc/login.defs
	   Shadow password suite configuration.

       chfn(1), login.defs(5), passwd(5).
