Join two lines

[39931481]

Hello,
I had been trying to extract two consecutive lines starting from a line containing words and send the output to another file, but was not successful. Can some one give me a hand on this please.
Here is the input file format. . . .

and I am trying to capture every line with "ARCO : Completed" phrase and the next line to it.

Thank you in advance,

One way:
awk '/ARC0: Completed/{print;getline;print}' /path/to/input

Hope This Helps, PH.

Hi, just a variation on the solved question... I modified the sample data. What if I need to get the words/data after ARC0: Completed archiving? And then save this in variables like
mylog=log 2
mythread=thread 1
