     -   A: I don't. If I am going to SSH somewhere, I just start vterm,
         and haven't thought about any interop.
+- Q: Where can I find your eshell/do command? Probably you also have another bunch of interesting Eshell helpers.

+- Impressive. eshell is an emacs REPL! I knew I could issue some emacs commands but not this level of interactivity. Thanks!
+- The real elisp REPL is ielm, but eshell is more generally useful.
+- eshell is a REPL focused on the specific niche of shell.  ielm's the pure elisp repl, and it rocks.
+- yes. i know ielm. just hadn't realised how powerful eshell is.
+- howard-abrams : every time I've watched a talk of yours over the years, Emacs/Org-mode has absorbed one more use cases of mine, and made them be in literate form. I'm down to Emacs and a web browser, so I'm looking ahead to your talk about the Web in Emacs :)
+- You can also leverage org-mode source blocks tu turn outputs into inputs to other blocks so, plenty of alternatives to pipes 
+- Wow! Eshell is awesome! I have just learnt more tips! Thanks howard-abrams!
+- I think of Eshell as my *universal* machine REPL, i.e. not just ielm for emacs/elisp nor a shell for the machine, but *both* emacs/elisp and the OS/env.. In that way it's quite neat.
+- howard-abrams: thank you, very inspiring! I've always found 'normal' command line usage somewhat cumbersome and am certanly going to look at the code
+- I really like eshell but I sometimes find the aliases a bit hard to write. alias f if $* {find-file $1; for i in {cdr {flatten-tree $*}} {find-file-other-window $i}} {echo "No files"} - Should probably use Elisp instead
+  - I think the aliases are almost completely broken, and only seem to work in the barest of cases.
+    - Yes, in particular the Lisp part is broken. In combination with $*
+      - I agree that you should write a function for that. Because as I mentioned in my talk, aliases don't accept $* at all.
+        - Oh, they do. This alias works. I don't recall the reason why I wrote this as an alias. I probably just wanted to use an alias where possible.
+          - Huh ... that works? I need to try it out. I couldn't get that working, so that is why I wrote the function that I did.
+- watching your talk now; TIL /dev/kill and /devl/clip
