searching sed inplace from stdout

Hello Folks,

I am searching a command where i want to write the replace string into files.

Below are the scenarios.

I have file called test.txt and the below are the contents.

[wininstall]
server1fqdn: server1.com
server1comps: ifwe=False ifge=False ifze=False

server2fqdn: server2.com
server2comps: ifwe=False ifge=True ifze=False

[endwininstall]

Now i am trying to replace 'ifge=True' to false in the text.txt file.

I tried the below commanad:

cat test.txt | grep -w server2comps | cut -d ":" -f2-14 | grep -oP 'ifge[^[:blank:]]*' | sed 's/True/False/g'

output:

ifge=False

But my question is how can write this changes in file directly using 'i' option.

Can any help me out this.
