Replacing a character from standard output on the fly

I'm not sure this is possible, but I'm trying to replace a character from standard output on the fly.

The issue is like this. A command c1 produces the output So, c1 | less gives me ABC

I would like to replace occurrences of B with D, so I get ADC.

If possible that my command chain should be something like

c1 | <something> | less

and print ADC instead of ABC.

use sed:

c1 | sed 's/B/D/' |less

For the given example of replacing "ABC" with "ADC". If you want to replace all occurrences of B on D use the option g (global)

sed 's/B/D/g'

You can find more using:

man sed
