Midnight Commander subshell trolling guard #1

Open midenok opened 10 years ago

To avoid horrible subshell trolling (when you forget and run MC under MC), you can do following dirty hack. Put this into your .bashrc:

check_mc()
{
    if [ -n "$MC_SID" ]
    then
        echo You are under mc!
    else
        "$@"
    fi
}

mc() { check_mc /usr/bin/mc "$@"; }
sudo()
{
    if [ -z "$1" ]
    then
        check_mc /usr/bin/sudo
    else
        /usr/bin/sudo "$@"
    fi
}
ssh() { check_mc /usr/bin/ssh "$@"; }

Better solution would be suspend MC and run command in parent shell. Anyone's try to make script for this is welcome!
