How to stop shell script if curl failed
Solution 1:
You can check for exit code using $?:
exit_status = $?
if [ $exit_status != 0 ]
then
exit $exit_status
fi
If you want to analyze exit status, take a look at the Exit codes section from man curl page. There are a lot of different codes, depending on why it failed.
EDIT : You can use command1 || command2 as well. command2 is executed if and only if command1 has failed:
curl .... || exit 1
Solution 2:
Just exit if curl ends with a non-zero exit code:
curl http://www.example.com || exit 1
Or, make your script exit on error:
set -e
curl http://www.example.com
