John, thanks for update.

as resilution we have options:
1. for reduce issues with differen shell on different platforms - need try to 
look Python or Perl or something similar based framwork.
2. try to find good way for PATH to correct tools with tests - probably it can 
depend on (1) and use definitions for tools in new frameworks
3. probably to look for universal replacements for DF, DU, FIND, GREP, SED, etc 
- probabbly by separate functions implementations for tests - also depend on (1)
4. anything else ?

Maybe someone know some tests framework what can be looked/investigated for 
automations ?
Ideas/links/ are welcome.

We need automation framwork, where we can specify setup/cleanup procedures and 
describe steps with tests.
this framework should provide abiliy for run one test or several tests.
