I have the following two files test.txt
and test1.txt.
I want to update the data of test.txt
in to test1.txt
under abc.com
, however, first it has to remove the existing data so final output looks like test1.txt
under output file section
test.txt
10.100.4.10
10.100.4.11
10.100.4.12
test1.txt
[abc.com]
10.100.44.10
10.100.44.11
[xyz.com]
10.100.55.10
10.100.55.11
[etc..]
OUTPUT FILE
test1.txt
[abc.com]
10.100.4.10
10.100.4.11
10.100.4.12
[xyz.com]
10.100.55.10
10.100.55.11
