Catch an error at nginx reload

Question

I have a bash script that's make some operation on nginx's virtualhosts. I would like to know how to catch error if nginx not reloading correctly (nginx reload).

I think to use nginx -t but i don't know to intercept error in a bash script.

Do you want to log those errors somewhere then? In a separate file? Or simply echo the error message? — David B., Oct 14 '16 at 09:41
I want to determinate result of `nginx -t` (0-> not correct, 1-> correct) like a boolean — Davide, Oct 14 '16 at 12:04

Why do you want to make changes and then direct reload Nginx ? It can cause Nginx to stop working.

A better process would be to make changes -> do a configtest -> if configtest == ok -> reload nginx.

You may want to try something like:

#!/bin/sh

#...your script
nginx -t
if [ "$?" != "0" ]; then
    echo "Error!"
    exit 1
else
    echo "All good"
fi
