Hi corona, your solution works for 0. I am wondering how to include other pattern which is 1011.

Scrutinizer, your command is picking up 0 on even lines as well.

Thanks so much for your effort

Code:
awk 'NR%2 { L=$0; next }; (L=="0")||(L=="1011") { print L; print }' datafile

That's right...
Code:
sed -n 'N;/^0\n/p;/^1011\n/p' infile
