Quick ASCII Binary Tools

Just going to leave this here (and here) in case anyone needs a quick set of source-able functions to make quick ASCII->Binary and Binary->ASCII conversions from Linux command lines. 🙂

chrbin() {
     echo $(printf \\$(echo "ibase=2; obase=8; $1" | bc))
}
 
ordbin() {
     a=$(printf '%d' "'$1")
     echo "obase=2; $a" | bc
}
 
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
     echo
}
