Scripnix: Useful Python3 and bash shell scripts for macOS/BSD and *NIX

A lot of these scripts have areas of nuance and subtlety that are likely not addressed.

The backup script that essentially runs cp "$x" "$x.$(date +%y%m%d)" would greatly benefit from the --reflink option to GNU cp, but only when running on a COW filesystem (ZFS or BtrFS). This particularly strikes me.

For those of us who nest tmux sessions:

  # Map a PID to a tmux session and window
  # in which to find that process (typically
  # $EDITOR):
  #
  function p2mux {
    local fmt='#{session_name} #{window_index} #{pane_tty} #{window_name}'
    find /tmp/tmux-$UID -type s -print0 |
    xargs -0i tmux -S '{}' list-panes -a -F "$fmt" 2>/dev/null |
    grep -w "$(ps -p "$1" -o tty= || echo pts/NO_SUCH_TTY)"
  }

Yes, I nest tmux sessions. I've one session per-project, each running in a window of the same name in a top-level session. I've a different prefix for the top-level (^T) and the nested sessions (^A, because old habits from the days of screen(1) die hard). Every $EDITOR instance goes in a window named after the basename of the file being edited. `p2mux` is very useful in this setup.

Using `pane_pid` to make this more compact is tricky because I want to find processes that might be stopped and not running in the foreground.

no offense but how is this getting so many upvotes?

Great way to take the fun out of using the Linux CLI.
