adding a new line using sed command

UNIX Solaris
1

I need to find text "A" and replace it with A B. The issue is that I need a new line between A and B. \n does not do the work. Any help would be much appreciated.

Thanks,

Use perl

perl -p -i -e 's/A/A\nB/g' somefile

Make a script file for sed, e.g....

s/A/A\
B/g

...use it like this...

sed -f myscript somefile
