Чем отличается последовательное выполнение команд в CLI через точку с запятой (;) и два амперсанта (&&)?

In CLI commands, separated by a semicolon (;), commands are executed sequentially one after another, regardless of the result of the previous command. That is, all commands will be executed even if one of them fails.

Commands separated by double ampersand (&&) are executed sequentially, but the next command only runs if the previous one completed successfully (exit code 0). If any command fails, the chain execution stops.

Example:

mkdir test_dir; cd test_dir; echo "Hello"

Will execute all three commands, even if mkdir or cd fail.

mkdir test_dir && cd test_dir && echo "Hello"

The second and third commands will only execute if the previous ones succeeded.
