UNIX Terminal commands can really speed things up, take grep for example if you are not sure of where you put a file or if some text is in a file you can run a simple command like this.
Find all references to “www.domain.com”
grep -R 'www.domain.com' /var/www/html
PowerShell has a similar command
cd C:\inetpub\wwwroot dir -Recurse | Select-String -pattern "www.domain.com" | Format-Table linenumber, filename, path, line -autosize
If you don’t want to show the line text you can leave off the ,line in format-table
cd C:\inetpub\wwwroot dir -Recurse | Select-String -pattern "www.domain.com" | Format-Table linenumber, filename, path -autosize
