Simple bash script to create apache2 virtualhost for localhost. Can be used for public subdomains on developer server with changes - "replace .localhost".

Tested on Ubuntu, but should work where dependency met.

Not for production, for development purposes only.

Use zenity for gui and pkexec for root permissions, so can be run without terminal, however some terminal output persist.

/etc/hosts file looks like: (so allowing add any subdomain)

127.0.0.1 localhost *.localhost

Note the wildcard, script doesn't create domains.

I'm not very experienced at bash scripting. Review and improve security, compatibility, maybe also some features with domains.

It's also on GitHub: https://github.com/LeonidMew/CreateVirtualHost
