These are interactive promts from converting between the different number formats to decimal and reverse.

# hex-dec
h2d() {
    echo
    echo TO DEC, ctrl+c to end
    echo
    while :
    do
        read -p "hex> " i
        echo "ibase=16; $i" | bc
        echo
    done
}
d2h() {
    echo
    echo TO HEX, ctrl+c to end
    echo
    while :
    do
        read -p "dec> " i
        echo "obase=16; $i" | bc 
        echo
    done
}

# oct-dec
o2d() {
    echo
    echo TO DEC, ctrl+c to end
    echo
    while :
    do
        read -p "hex> " i
        echo "ibase=8; $i" | bc
        echo
    done
}
d2o() {
    echo
    echo TO OCT, ctrl+c to end
    echo
    while :
    do
        read -p "dec> " i
        echo "obase=8; $i" | bc 
        echo
    done
}

# bin-dec
b2d() {
    echo
    echo TO DEC
    echo
    while :
    do
        read -p "bin> " i
        echo "ibase=2; $i" | bc
        echo
    done
}
d2b() {
    echo
    echo TO BIN, ctrl+c to end
    echo
    while :
    do
        read -p "dec> " i
        echo "obase=2; $i" | bc 
        echo
    done
}

Put these into your ~/.bashrc.

Enjoy.
