Örnek kimliği, etiket adı, maliyet merkezi, sahibi gibi başlık içeren bir dosya yazmak istiyorum. ve bunun altında JSON çıkışındaki belirli değerler. Burada verilen çıktı sadece bir örnek.
Nasıl kullanarak da yapabilirsiniz sed
ve awk
?
Beklenen çıktı :
Instance id Name cost centre Owner
i-1234576 RDS_Machine (us-east-1c) 1234 Jyoti
