Unable to translate IP addresses using tr

Question

I have a file that has lot of IP addresses. I need to change those IP addresses into some numbers. Below is how a file "data" will look

152.14.12.1
152.14.12.2
152.14.12.3

When I execute cat data | tr -s '152.14.12.1' '9', it replaces everything and the output is 9 9 9 9. How to do this. Any help would be appreciated.

Answer 1

Maybe you prefer to use sed, to replace a string, and not tr that is intended for a SET of chars, like:

cat data | sed "s/152.14.12.1/9/g"

gives you:

9

152.14.12.2

152.14.12.3
