About
A list of command is a sequence of one or more pipelines
- separated by one of the operators: ‘;’, ‘&’, ‘&&’, or ‘||’,
- and optionally terminated by one of ‘;’, ‘&’, or a newline.
| Control Operators | Definition |
|---|---|
| ; (Semicolon) or newline | Delimit commands, start a command sequentially |
| & (Ampersand) | Start a command asynchronously |
| && (AND) | The next command is executed only if the first command returns true |
| || (OR) | The next command is executed if the first command doesn't return true |
