|
|
- embodies unix principle: separation of concerns
|
|
- minimal -> shell just manages interaction of other small tools
|
|
- highly programmable; supports complex automation
|
|
- bad
|
|
- has quirkiness that can trip everyone up
|
|
- tradeoffs
|
|
- Shell can be perfect to some tasks; terrible for others
|
|
- extremely powerful however also difficult to learn to use
