Use Curl For Finding DataBase Errors?

Question

I have a list of domains in a file say list.txt I've got a report that many of these domains showing "Database Connection Error" I want to know all domains that can't connect with db properly. I thought curl could be a useful utility for that, so I try

curl -sSf http://`cat list.txt` > /dev/null | grep -I "database connection error" 

But with that I get whole bunch of other issues, I still get others errors in output, also (the bigger concern) I do not get domain name for which that error outputs. Please someone help me.

Answer 1

Make the things in loop.

for i in `cat list.txt`; do if [ "$(curl -sSf http://$i 2>/dev/null | grep -i 'database connection error')" != "" ] then echo $i fi done
