Is there a command that when run on a binary
file shows 0s and 1s instead of gibberish ?

cheers,
chax.

The od command is probably what you're after, although it doesn't
support binqary output (but hex and octal are supported).

If you don't find any, why don't you write your own tool? It's probably not
more then like 10-15 lines of code in C.

I already wrote a small script before I posted this
query. I also wrote a program (I require it)
. which takes 0s and 1s sequence (char or int)
and pack it into binary file..
I wanted to know if a command or some function
already exits to do the same .. especially the
second one..

thanx
chax.

In case anyone is having trouble finding it, xxd comes with vim.

"xxd -i" is one of the most useful tools in the world. I seem to
rediscover it every few years. And 'xxd -b' can do what the op wants.
