Replace /1/ to /2/ using sed
 

Greetings!

I would like to replace a number along with '/' to a new number but I couldn't figure it out.

I have tried the following:

There are other numbers which should be unchanged, except the matched patter ones.

Thanks in advance!

you need to use another delimiter, for example ! instead of /

Is it not possible to use "/" as delimiter?

Try using something besides a slash for your replacement delimiter so it's easier to read and that so you won't have to escape the slash you are searching for. sed does not care what it is as long as you use three of a kind.

See:

However, you might want to think out the logic of how you are going to replace all 10 digits one at a time. You'll probably need a non-digit place holder for one of them.

It is definitely possible, in that case you need to protect all the / chars using \

Okay, I will do as suggested. Thank you.
