How to replace one line with three in sed
Hi,
I have a problem. I want to use SED to replace one line with three
It looks like:
PARAM='first_line,second_line,third_line'
And in file:
blablabla
blablabla
PARAM
blablabla
blablabla
blablabla

All I want is to change this into:

blablabla
blablabla
first_line
second_line
third_line
blablabla
blablabla
blablabla

I did it like:

Code:
sed 's/PARAM/first_line\nsecond_line\nthird_line/' file_with_blablabla

awk '/PARAM/{print "firstline\nsecondline\nthirdline";next}1' file

Export the PARAM variable to the environment otherwise whatever solution you use will not work.

Code:
export PARAM='first_line,second_line,third_line'

awk '/PARAM/{system("echo $"$0)};!/PARAM/' file | tr ',' '\n'
