FLoM is a free open source distributed lock manager that can be used to synchronize shell commands, scripts and custom developed software. When used in a shell environment, FLoM manages process synchronization in the same way that "nice" manages process prioritization. Shell commands, scripts and custom programs can be synchronized inside a single system or in a network of IP connected systems. FLoM supports different types of abstract resources: simple, numeric, set, hierarchical and transactional sequence. libflom, the library shipped with FLoM, allows you to develop your own application using a simple C, C++, Java, Perl, PHP or Python client API. SSL/TLS security for network communication, X.509 certificates for peer to peer mutual authentication.

A new system shell, which is (in some regards) stronger than even Windows Command prompt, made in pure C. This terminal is fairly new, and doesn't require any complex installing process. You just download it, and then immediately use it! HTerminal has an improved console interface with modern buttons. It only has 28 commands, but it is useful none the less! And, if you're already reading this, then why not give it a try? It is completely free and takes up less than 1 MB of space + you don't even have to install it. It is ready to be used the second you download it! And, worst case scenario, you just stop using it. And if you enjoy our app, give it a rating, and maybe tell us about newly discovered bugs! It is much appreciated because it gives feedback that helps us improve HTerminal for you.
