  ./zwatcher.sh -u x.com/script.js -s 60 -o out.txt -mc 200 -sc -title -n notifyid

Examples

1. Monitor a single domain with a scan interval of 60 seconds and save the results to scanresults.txt:

./zwatcher.sh -u example.com -s 60 -o scanresults.txt

1. Monitor a list of domains from a file called domains.txt with a scan interval of 120 seconds and save the results to scanresults.txt:

./zwatcher.sh -l domains.txt -s 120 -o scanresults.txt

Examples for javascript files

1. Monitor a list of js files in list called js-urls.txt with a scan interval of 120 seconds and save the results to scanresults.txt:

./zwatcher.sh -l js-urls.txt -s 120 -o scanresults.txt

1. Monitor one js file https://hackerone/scripts/admin.js with a scan interval of 120 seconds and save the results to scanresults.txt:

./zwatcher.sh -u https://hackerone/scripts/admin.js -s 120 -o scanresults.txt

Notifications

zwatcher can notify you when changes are detected. To enable notifications, you need to have the notify command installed, which allows sending notifications to the desktop.

The notify command can be installed using the following command:

go install -v github.com/projectdiscovery/notify/cmd/notify@latest

After installing notify, you can specify the notification ID "from notify config file" using the -n flag:

./zwatcher.sh -u example.com -s 60 -o scanresults.txt -n mynotifyid

When changes are detected, zwatcher will send a notification with notify.

Notes

• If the output file (o flag) does not exist, zwatcher will create it when the first scan is completed.
• If you specify a file containing a list of domains (l flag), zwatcher will continuously scan each domain in the list with the specified scan interval.
