［原创脚本］ sussh：一个使su能forward X的脚本。

yongjian

虽然现在多用sudo来执行root权限,但有时在某些情况下还是会用到su, 特别是在远程没有sudo配置的环境。这样，在转换到另外一个用户后(多数是root), X authentication的信息就丢失了。自己写了一个脚本可以使到su到另外一个用户后仍能保持X权限， 运行X apps.

# Description:
# Allows one to su to another user within a SSH session and still be
# able to launch X11 apps.

# Check to see if a user id was supplied on the command line
case $# in
        1) uid="$1" ;;
        *) echo "Usage: $0 <username>"
        exit 1 ;;
esac

# Check if $DISPLAY is set
if [[ $DISPLAY = "" ]]; then
        echo "The DISPLAY environment variable must be defined."
        echo "You may need to turn on X11 forwarding in your SSH client."
        exit 1
fi

if [[ $(echo $DISPLAY | grep "localhost") != "" ]]; then
        DISPORT=$(echo $DISPLAY | awk -F: '{print $2}'| awk -F. '{print $1}')
        NEWDISPORT="$(uname -n)/unixDISPORT"
else
        NEWDISPORT=$DISPLAY
fi

XAUTH="/usr/bin/X11/xauth"        # Set the location of xauth
ARG=$($XAUTH list $NEWDISPORT)   # Get the X11 magic cookie

su - $uid -c \
"$XAUTH add $ARG; \

SSH_TTY=$SSH_TTY; \
SSH_CLIENT='$SSH_CLIENT'; \
export DISPLAY SSH_TTY SSH_CLIENT; \
