I have a numeric output from command, let's say:
sh -c 'exit 1' ; echo $?
or
bc <<< "1 + 1"
And I need to send it in GET request via curl, like http://example.com/?value=1
I've tried this:
sh -c 'exit 1' ; echo $? | curl -G -d @- http://example.com/
but it just got param with a name 1
and empty
value.
I know I can do something like:
result=`sh -c 'exit 129' ; echo $?` | curl -G -d value=${result} http://example.com
but I'd like to keep the first part of command unchanged and modify only part after pipe. Is it possible?
One possible solution I found:
sh -c 'exit 129'; echo $? | xargs -I '{}' curl -G "http://example.com?value={}";
