How to convert binary number to text/ascii?

Hi,
is there command in linux which is able to convert binary (0101001010000100) to text like it means something?

Thx

bc ibase=2 0101001010000100 should do the trick.

EDIT: I found another article that says you need to use echo and pipe to bc like this

Code:

echo 'ibase=2;obase=A;0101001010000100' | bc

EDIT2: If you want to use wcalc, just do

Code:

wcalc 0b0101001010000100

The "0b" at the beginning means it is a binary input.

I noticed those examples convert over, but not to the actual ASCII characters; ie 01110100011001010111001101110100 to test. Is there anyway to do that?

Try

Code:

bin='01110100011001010111001101110100'

printf $(echo "obase=16;ibase=2;$bin" | bc | sed 's/../\\x&/g')



test

EDIT
Any non-printing characters can be converted to a dot or deleted using tr

Code:

printf $(echo "obase=16;ibase=2;$bin" | bc | sed 's/../\\x&/g') | tr -c '[:print:]' '.'
