+sshfs
+-----
+
+As a non-root user,
+you can mount remote file systems locally with `sshfs`.
+It's probably as close as Unix is going to get for a while,
+and it's not awful.
+
+
+lm
+--
+
+The plan9 `lm` command is great:
+it's like `apropos` or `man -k` but it outputs lines you can
+copy and paste into a prompt to pull up the page.
+Here's a script to do the same thing with Unix:
+
+	#! /bin/sh
+	apropos -l "$@" | sed 's/\(.*\) (\(.*\)) * - /man \2 \1 # /'
+
+
+xdg-open
+--------
+
+This is the current Linux notion of how to do things like the plumber.
+Just about every modern program calls out to it to open files,
+and it uses whichever one is first in your path,
+so you can make a little script to do what you want and
+avoid having to configure all the weirdo files in ~/.config
+
+	#! /bin/sh
+	case "$1" in
+		*://*)
+			exec web "$1"
+			;;
+		*.pdf)
+			exec my-pdf-viewer "$1"
+			;;
+	esac
+
+
+mon
+---
+
+Russ Cox uses a program called `mon`
+to watch files and run them whenever they change.
+This is pretty handy for iterative debugging,
+you don't have to keep re-running your program every time you
+save/compile.
+
+Here's a start at one.
+It can be improved.
+
+	#! /bin/sh
+	while true; do
+		gonow=
+		stat=$(stat --format=%Y.%Z.%s $1)
+		if [ "$stat" != "${laststat:-$stat}" ]; then
+			laststat=$stat
+			gonow=yes
+		fi
+
+		if [ -n "$gonow" ]; then
+			echo "[[=== start ===]]"
+			$@
+			echo "[[=== done ===]]"
+		fi
+		laststat=$stat
+		sleep 1
+	done
