ASCII to Binary and Binary to ASCII conversion tools?

Which is a good tool to convert ASCII to binary, and binary to ASCII?

I was hoping for something like:

$ echo --binary "This is a binary message"

01010100 01101000 01101001 01110011 00100000 01101001 01110011 00100000 01100001 00100000 01100010 01101001 01101110 01100001 01110010 01111001 00100000 01101101 01100101 01110011 01110011 01100001 01100111 01100101

Or, more realistic:

$ echo "This is a binary message" | ascii2bin

01010100 01101000 01101001 01110011 00100000 01101001 01110011 00100000 01100001 00100000 01100010 01101001 01101110 01100001 01110010 01111001 00100000 01101101 01100101 01110011 01110011 01100001 01100111 01100101

And also the reverse:

$ echo "01010100 01101000 01101001 01110011 00100000 01101001 01110011 00100000 01100001 00100000 01100010 01101001 01101110 01100001 01110010 01111001 00100000 01101101 01100101 01110011 01110011 01100001 01100111 01100101" | bin2ascii

This is a binary message

PS: I'm using bash

PS2: I hope I didn't get the wrong binary

ascii binary bash

Using bc and bash:

#!/bin/bash



chrbin() {

        echo $(printf \\$(echo "ibase=2; obase=8; $1" | bc))

}



ordbin() {

  a=$(printf '%d' "'$1")

  b=$(echo "obase=2; $a" | bc)

  printf '%08d' $b 

}



ascii2bin() {

    echo -n $ | while IFS= read -r -n1 char

    do

        ordbin $char | tr -d '\n'

        echo -n " "

    done

}



bin2ascii() {

    for bin in $

    do

        chrbin $bin | tr -d '\n'

    done

}

ascii2bin "This is a binary message"

bin2ascii 01010100 01101000 01101001 01110011 00100000 01101001 01110011 00100000 01100001 00100000 01100010 01101001 01101110 01100001 01110010 01111001 00100000 01101101 01100101 01110011 01110011 01100001 01100111 01100101
