Top Forums Shell Programming and Scripting awk: reading into an array and then print the value corresponding to index Post 302328592 by akshaykr2 on Wednesday 24th of June 2009 05:47:48 PM

Thanks a lot! I really appreciate your help

---------- Post updated at 05:47 PM ---------- Previous update was at 05:23 PM ----------

What values are assigned to array f[$1]? I understand its indexed by $1 of file opnoise. Or I guess the index does not matter in this case, its just creates an array with all the records in $1 of file opnoise. Am I thinking right? Could you please further explain the meaning of f1[$1].
