The following code I added in the /etc/profile
# Be sure that VUE does not invoke tty commands

if [ ! "$VUE" ]; then

# set term if it's not set

if [ "$TERM" = "" -o "$TERM" = "unknown" -o "$TERM" = "dialup" \
-o "$TERM" = "network" ]
then
eval `ttytype -s -a`
fi

export TERM

# set erase to ^H, if ERASE is not set
if [ "$ERASE" = "" ]
then
ERASE="^H"
export ERASE
fi
stty erase $ERASE
fi #VUE IF

Some commands return an error for a background shell. In almost every case, we only ever want these commands to run when we are in an interactive shell.

Use the tty command to stop a command from running in a non-interactive shell:

tty > /dev/null && {
 ... place interactive shell commands here ...
}
