Examples of Unix/Linux Programming
Circling Cycle and its staff engaged in numerous Unix and Linux scripting projects over the years.The main reasons the scripting languages are favored are:
- Readily available on all platforms at no cost
- Processor-independent
- No compilation required
- Powerful modules and extensions
- Proven track of their implementation even on largest projects worldwide
- Simplicity versus unnecessary complexity
