Como usar o comando grep para mostrar a saída abaixo?

    

Answer 1

Você pode usar o grep com -A . Algo como:

$ grep -A 13 '^\[2\]' inputfile.txt

O -A especifica o número de linhas que você deseja incluir após a correspondência.

Mas acho que seria melhor usar sed neste caso:

$ sed -n '/^\[2\]/,/^$/p' inputfile.txt

Isso imprimirá tudo entre [2] e uma linha vazia.

O mesmo usando awk :

$ awk -v RS='' -v ORS='\n\n' '/^\[2\]/' inputfile.txt
