Remove duplicate consecutive lines with specific string
Hello,

I'm trying to remove the duplicate consecutive lines with specific string "WARNING".

File.txt
Code:
abc;
WARNING 2345
WARNING 2345
WARNING 2345
WARNING 2345
WARNING 2345
bcd;
abc;
123
123
123
WARNING 1234
WARNING 2345
WARNING 2345
efgh;
1234
1234
12
134
WARNING 2345
WARNING 1234
WARNING 1234

Output should be something like this -
out.txt

Code:
abc;
WARNING 2345
bcd;
abc;
123
123
123
WARNING 1234
WARNING 2345
efgh;
1234
1234
12
134
WARNING 2345
WARNING 1234

I have tried sed but didn't accomplish what I'm trying to achieve -

Code:
sed -r 'N; /(WARNING)[^\n]*\n\1/ s/\n.*//; P; D' File.txt
abc;
WARNING 2345
WARNING 2345
WARNING 2345
bcd;
abc;
123
123
123
WARNING 1234
WARNING 2345
efgh;
1234
1234
12
134
WARNING 2345
WARNING 1234

Please provide your suggestions to do that using sed or any other method.

Thank you.
