dont know what sudo is or how to use it.
i have seen it in scripts though.
something that through a terminal, i can be logged into fluxbox and run a program as a different user (not root)
thanks

Re: run program as different user

su username

allows you to switch to any user in the terminal.

http://wiki.archlinux.org/index.php/Roo … %20Desktop

tells you how to enable GUI programs for other users. I'm pretty sure it works for all users, not just root.

HTH,

Re: run program as different user

this will allow you to run applications as a different user in an X session. It's not mine - I got it from somewhere but I don't remember it anymore.

#!/bin/sh
# usage is: 
# save as ~/script-name
# chmod +x script-name
# ~/xsu username 'programname &'
# ex: 
# ~/xsu john 'firefox &'

if [ $# -lt 2 ]
then echo "usage: `basename $0` clientuser command" >&2
     exit 2
fi

CLIENTUSER="$1"
shift

# FD 4 becomes stdin too
exec 4>&0

xauth list "$DISPLAY" | sed -e 's/^/add /' | {

    # FD 3 becomes xauth output
    # FD 0 becomes stdin again
    # FD 4 is closed
    exec 3>&0 0>&4 4>&-

    exec su - "$CLIENTUSER" -c \
         "xauth -q <&3
          exec env DISPLAY='$DISPLAY' "'"$SHELL"'" -c '$*' 3>&-"

}
