tips

  1. Commands can be abbreviated to save on typing, as long as they are unambiguous:

    ```bash

    these are the same

    psfu tree show affinity psfu t s a ```

  2. Use piped input to show forest or to modify multiple process trees:

    ```console $ pgrep 'tmux: server' | psfu t s a 1459 tmux: server [0, 1, 2, 3] ├── 1460 bash [0, 1, 2, 3] │ └── 3764 emacs [0, 1, 2, 3] │ ├── 108151 aspell [0, 1, 2, 3] │ └── 111340 rust-analyzer [0, 1, 2, 3] │ └── 111370 rust-analyzer [0, 1, 2, 3] └── 3772 bash [0, 1, 2, 3] └── 114364 psfu [0, 1, 2, 3]

    $ pgrep emacs | psfu t m a 0

    $ pgrep 'tmux: server' | psfu t s a 1459 tmux: server [0, 1, 2, 3] ├── 1460 bash [0, 1, 2, 3] │ └── 3764 emacs [0] │ ├── 108151 aspell [0] │ └── 111340 rust-analyzer [0] │ └── 111370 rust-analyzer [0] └── 3772 bash [0, 1, 2, 3] └── 114399 psfu [0, 1, 2, 3] ```
