[talk] I declare not so stupid unix tricks thread open

[Mischa Diehm]

On systems that have lsof  (could probably be changed for fstat): 

# fast changedir to directories already open by other shells
fcd () {
        COUNT=0
        lsof -d cwd | grep '^bash' | sed -e 's/^.* \///' | \
            sort -u | grep -v '^home/mischa$' | while read i; do COUNT=$((COUNT+1)); echo "[$COUNT] /$i";  done

        read j;

        case $j in
            [1-9])
            DIR="/$(lsof -d cwd | grep '^bash' | sed -e 's/^.* \///' | sort -u | \
                grep -v '^home/mischa$' | sed -n ${j}p)"

                if [ "$DIR" != "/" ]; then
                    cd "$DIR"
                fi

                ;;
            *)
                ;;
        esac
}
