Using jq with bash to run command for each object in array
With xargs:
curl localhost:8082/connectors | jq .[] | xargs -L1 -I'{}' curl -XDELETE 'localhost:8082/connectors/{}'
Or equivalently, to show the output of that first curl:
echo '["quickstart-file-sink4","quickstart-file-source","quickstart-file-sink","quickstart-file-sink2","quickstart-file-sink3","quickstart-file-source2"]' | jq .[] | xargs -L1 -I'{}' curl -XDELETE 'localhost:8082/connectors/{}'
jq .[]
strips off one level of containment, so that a list becomes output as one line per item.
xargs -L1
processes one line at a time
xargs -I'{}'
specifies that the string {}
be replaced with the input line when invoking the following command.
xargs
is essentially a map operator for the shell.
Your best bet is probably to output each record in something like TSV format, then read that from a shell loop.
jq -r '.[]|[.user, .date, .email] | @tsv' |
while IFS=$'\t' read -r user date email; do
mycommand -u "$user" -d "$date" -e "$email"
done
jq
itself doesn't have anything like a system
call to run an external command from within a filter, although it seems that they are working on it.
