Get the host from where you logged in

who -m | sed 's/.*(\(.*\)).*/\1/'
Will print the host associated with the current stdin. This is useful to set the DOIT_SERVER for the doit remote execution agent ( http://www.chiark.greenend.org.uk/~sgtatham/doit/ ) export DOIT_HOST=$(who -m | sed 's/.*(\(.*\)).*/\1/') Note that SSH_CLIENT variable can be lost if you use su or sudo (if set to reset vars)
Sample Output

@bashrc: It is not duplicated. You could read the description at least: "Note that SSH_CLIENT variable can be lost if you use su or sudo (if set to reset vars)"
