Nice use of jc
and jq
!
Just a quick note that you don't need to pipe the output of jc
to jq
when assigning the JSON output to a variable:
result=$(ping -c $attempts -M do -s $bytes -W $timeout "${host}" | jc --ping -p | jq)
can be simplified to:
result=$(ping -c $attempts -M do -s $bytes -W $timeout "${host}" | jc --ping)
I also removed the -p
in the jc
command since it only makes the JSON pretty and is not needed for parsing.
You could even simplify this further with the jc
magic syntax, but I tend to prefer pipes for some reason:
result=$(jc ping -c $attempts -M do -s $bytes -W $timeout "${host}")
Cheers!
