#### Shells
|
|
- start and stop OS processes
|
|
- used to control OS
|
|
- connect output of one OS process to input of another process -> this is the idea of [Unix pipes](None)
|
|
- manage environment variables: pass params to programs
|
|
- parse and evaluate command line instructions from user |
