Aw, I loved TECO - so much so that I wrote a version for every platform 
I used after that until I got into consulting for various different 
companies that used UNIX's of various flavors.

At some point in that transition, I learned vi. Now I wouldn't do 
without it.

The only detrimental thing about TECO to me, was that it was used to 
start off EMACS. ;)

I'm glad that I'm not the only one who remembers TECO; a fun game was to 
type your name at it to see what it did.

I've started using it again; at least until I can get vi running under

I’m a bizarre UNIX relic.    I never learned vi.   I went from “ed” to the various emacs variants (starting with Warren Montgomery’s EMACS, then JOVE and UNIPRESS, and later GNU).     I used INed (a commercialization of the Rand editor) but didn’t particularly like that either.    My coworkers for years would be amused when if I found the machine had no EMACS variant, I’d just use ed.    I could be startlingly fast in ed and you do learn regular expressions well if you have to do a lot of editing that way.    On a few machines where I’m confronted with VI and no ed/emacs, I just use VI in “ex” mode.

A great game to play while traveling is to interpret what license plates do in TECO.

A previous boss insisted that all his support staff learn ED, because one 
day it might be the only editor available on a trashed box (you can't 
mount /usr etc).

That's happened to me relatively recently (I know ed just well enough to get machines out of that state).

Of course nowadays you can't rely on the thing called 'ed' being 'ed': I know someone who lives in ed but can't run it on some machines because it relies on something in /var somewhere being writable, which it isn't.  I've always thought that the *whole point* of ed was that it did not rely on vast tracts of the system actually being there, still less beng functional.  This person now has to edit things with cat (which, in some future release, will probably start assuming that there's a configured ipv6 interface or something, because why would that ever not be true?).

Hi Ronald,

One thing I miss with vim(1) is the lack of open mode, the half-way
house between ex and vi modes.  I still use ed daily when I know the
edit I want to do and have the context to work by, e.g. output from
previous commands, on the screen, that I don't want removed by a
full-screen editor.  But sometimes it would be nice to be able to `f(c%'
rather than always have to regexp the edit and vi's open mode would give
me that.

I've idly considered an ed that also maintained a cursor within the line
that could be used with vi-like commands.

But seriously, you want an ed with a cursor, you need only take
GNU ed and hook it up with GNU readline, and there you go.  If
GNU ed doesn't already have such support.  Absolutely no need to
reinvent either wheel.

My two cents,

That would allow me to edit the command I'm entering, e.g. `,n'.  What
I'm suggesting is the command I'm entering can manipulate the in-line
cursor when I press Enter to submit the command.  I don't want
interactive editing of lines in the file;  I know where to find that.

ed 1.14.2-1 here hasn't.  And I wouldn't expect its dependencies to
grow.

Since `ed` is line-based, one could presumably use it with `rlwrap` or
something like that.

I don't think I understand what you're getting at. It's been decades,
I think, since I last saw / used open mode, which is what I thought
you wanted, so I think I'm confused.

I think what Ralph wants is something like "LINES=1 vi"
but without clearing the screen so that commands that
are cursor relative can work. rlwrap and readline don't
edit the current line in the file, only the command input.

OK, that I can understand.  It's ages since I played with
readline, but I think you can preload the buffer it works on
(bash does that, no?) so ed + readline could be made to work
that way.

At least, I think so.

I already have too many side projects on my plate, or I'd try it. :-)

Editing that way seem is bass ackwards -- probably more code
would needed to interface with readline than just implementing
it in ed. As a one line version requires just line movement
commands, there is no reason why you can't use full power of
vi through a narrow window - such as d} to delete to the end
of para and have the next line dispayed. Readline wouldn't
help there. And readline weighs in @ 28K LOC to ed's 3.5K (on
plan9 it is under 1.6K).

Yes, you can set a startup hook to preload the buffer contents. Bash
uses that for `read -ei'.

Sorry if I wasn't clear.  I miss open mode as vim doesn't have it, and
I'd sometimes find it useful.

Separately, I use ed regularly, and have though about its `compose a
command, submit it', model being extended to commands that act upon a
cursor that's within the line, just as `.' is the line within the file.
I don't mean readline editing of the command, nor of the current line in
the file.  More what one might see on the RHS of `:map Q ...', but in
the style of ed.

Stan Rabinowitz once asked a question in DEC's Trivia NOTES
conference:  "What do these two-character sequences have in common?"
There followed four sets of two special characters.  The answer was
that those were the only two-character sequences that were NOT valid
TECO commands.

For all that it's the butt of jokes, ed is awesome. I didn't really 
appreciate it until vi wasn't an easy goto option anymore (v6). After 
reading Kernighan's tutorial, I kind of fell in love with it. g/re/p? 
Who'd of thunk it? ed may not be 'visual', but the entire document is 
editable and its support of regex and the global command are incredibly 
powerful. Especially, for so incredibly tiny an editor. Finally, ed is 
the sibling of sed and once I got the connection there, it opened up a 
whole new world of editing awesomeness.

It took me a while to realize that ed(1) is what TECO should have been....
Too much TECO trauma scared me away for far too long.... But maybe it was
all the TECO macros I wrote to make the BH100 terminal useful as an editor
in full screen mode....

TECO (and therefore Emacs) and ed(1) represent two completely opposite
views on software development and IT in general.  The one is
fanatical about minimalism and 'less is more' approach, while the other
stands for 'more is more'.

That is why MIT and Bell Labs represented two very different cultures.  In
the history of computing I have not found any other group of computer
scientists that so deeply emphasized minimalism and 'less is more' approach.

This group produced the original UNIX and C, Plan 9, and Go programming
language.  Everything else in the Unix camp including BSD, Linux or GNU was
never about minimalism as its main goals, although one can argue that in
the early years Linux kernel was small and minimal.

Parent.  :-)

Something I learned today was (sed's author) McMahon's method of
arranging a tournament.

    ...was originally used as a club ranking system at the New York Go
    Club.  It was then adopted for Go tournaments in Britain, and has
    since become the most popular tournament system used in Go.

I still don't get what was so bad about TECO.

*20t$$
<20 lines of text>
*fs<text to search for>$<text to replace it with>$$
*0lt$$ ; type current line to review what you've changed.

Very simple.

*<fstextsearch$textreplace$>$$

replace all occurrences of textsearch.

Now, of course, searching for something like a regular expression was 
much harder.

Q-registers, all sorts of cool stuff.

But then, maybe I'm talking about a later version of TECO than you all. 
I think I was on version 22 on TOPS-10 6.03A

[TUHS] basic tools / Universal Unix

[Clem Cole]

Teco commands were described as being 'indistinguishable from line noise.'
  On 10/30/120 cps dial up lines, that was not always a good thing ;-)

One of my favorite stories of teco years ago, one of my friends was editing
a teco macro and had gotten up from his terminal for a minute, his wife
looked at the screen and asked him if his 2 year old has been attacking the
keyboard again.

BTW:   My friend and former co-worker, Paul Cantrell wrote an excellent
teco implemnentation for UNIX.   I believe if you go to his web site (
copters.com) and poke around its available for download.

Tom Almy's version, based on Pete Siemsen's TECO implementation
is available as a FreeBSD port. Also runs on a bunch of other
platforms. A more recent version with Blake McBride's changes
is at https://github.com/blakemcbride/TECOC. I had used TECO a
long time ago on TOPS-10 so I played with this version but it
feels completely foreign to me now:-)

Suddenly I fell like I'm in a TECO support group ;)

I have my own implementations of TECO - both on UNIX and MSDOS (of all 
things). They both do colorization of structured programming, something 
that preceded EMACs colorization by a few years.

I always wondered if my released MSDOS version of TECO gave people ideas.

When did EMACS start coloring things? I started it in my TECO as of 
around 1984-1985 - it supported it in text strings, parentheses, etc. 
 From my MSDOS version, showing some MASM code:



The structured macros were inspired by Bruce Maier's structured macros 
he did for MACRO-10 on TOPS-10 in the mid to late 70's.

​I'm fairly sure, Gosling EMACS could do color by '83 when we had it on the
Masscomp systems.​  Cantrell's Teco was a year or two later always support
color in some manner, because was a graphics guy at Masscomp (and DEC
before that).

I'm dating this by, the fact I had left Berkeley by then.   PC or one of
the HW folks  had written a set of EMACS macro's to emulate VMS's EDT for
the ex-DEC HW guys which used color.   The MIT contingent was all EMACS,
but we switched to Zimmerman's EMACS when we hired Steve I want to say in
84 or 85. I remember there was some heartache because Zimmerman EMACS was
very close to ITS EMACS and preferred by the ex-MIT folks (unlike Gosling
EMACS).   But the color stuff for EDT broke and there was complaining from
the HW folks.  [Andy Tannenbaum, Eric Ginger and I were the die hard ed/vi
folks - which in those days was BW - to this day even with vim, I still
rarely use colors with that editor].

It's always interesting how parallel development happens with certain 
things.

I certainly had no exposure to EMACS at the time I came up with the 
idea, nor the rest of this community you describe.

I'm not sure I like vim's coloring, actually. I find myself having to 
search for a nonexistent string just to get rid of it's highlighting of 
a search string.

`:noh' turns off the highlighting of the current matches.
They start again on the next search, e.g. `n'.
In less(1), it's `Esc u'.

YAY!

I've been using Arthur Krewat's method, basically /asdf<CR>,
for a long time now.  Now I have:

    map <Leader><Leader> :nohlsearch<CR>

in my .vimrc (<Leader> is backslash, so after /foo<CR>, \\ turns
off the highlighting).

One other really useful thing, given issues with tabs vs spaces,
that I'll share here, comes just before this new entry:

    function! ToggleTabs()
        if &list
            set nolist
        else
            set list listchars=tab:>.,trail:>,precedes:<
        endif
    endfunction

    map <Leader>t :call ToggleTabs()<CR>

With this, \t makes tabs visible, or invisible if they are
currently visible.  Despite the name it also highlights trailing
whitespace (the highlight is a bit subtle though).

I hit send too soon.

Credit goes to @Gumnos for the idea.

I also like the fact that ^L causes screen redraw, so double duty.

I recommend said person install `ed' from the Heirloom project: it's a
traditional version (with added support for UTF-8). It will even work on
modern GNU/Linux (I know for sure because it's the one I use).

Speaking of which, am I the only one annoyed by Penguin/OS' silly coloured

I find the colours awful, and have that stupidity turned off, along with 
the coloured prompt, the ridiculously long path in the prompt, and set 
MANPAGER="less -X" so as not to disappear manpages.

I *think* that's because some global file does something like

	alias ls='ls --colors'

You can verify with

	type ls

Try running

	unalias ls

and see if that helps.

Hey Clem,

lol, it’s funny, but there’s still lots of stuff I use it for despite the
fact that I haven’t really worked on it in years.

There’s a version up on the net here: http://videoteco.cvs.
sourceforge.net/viewvc/videoteco/videoteco/

although I can’t say how well that builds these days… Still, people are
welcome to give it a try.

I keep thinking about re-writing it in a modern language…

PC did his original development on a Masscomp box which was basically 4.2
APIs and was one of the original X systems (its what ORA did the original
doc and how Tim got his start).  Paul is a Mac guy (at one point it
compiled on the 68K Mac OS) and he moved the development there at one
point.  So, I suspect it will build without too much difficulty on *BSD
style systems (and he might even answer a question or two if you run into
issues).

I suggest try it and see how far you get.   The biggest issue is the video
calls were for older versions and I don't think they talk to modern API's;
but I suspect on the Mac the X windows system will work fine.

Then again, I have not tried it in years and I'm not sure at this point, I
could pull teco commands out of my long paged out personal memory system.

It builds, with a number of warnings - the most concerning of which are
pointer/integer casts on 64-bit systems (most seem to be debug printing,
but there are a couple that aren't), but seems to run okay - I don't
know any teco to really exercise it though.

Thanks, all; I'll just knock up a simple script that blows away the entire 
environment and unaliases everything in sight.  I'll probably call it 
"orca" because I have a warped sense of humour...

Unix taught me to be minimalist; you had to be when writing a bootstrap to

If you happen to be on Red Hat derived Linux, the easiest way to turn off
all this crap is to rename /etc/profile to something like /etc/profile.dist
and then populate your own startup scripts.

For a minimalist prompt I just use:

Certainly not.  But I don't think it's all Linux.  I've summarized how
to fix this and other annoyance in my Linux HOWTO page:

I THINK that I don't like ls colours, but I have to admit that since I
started trying to pay attention more, I find colour coding has some
value, for some meaning of some and no value defined.

Actually no, I still hate colour LS. I like ls -F because the implied
extra information can be semantically extracted with a grep, although
why find . -type d -maxdepth 1 isn't being used is beyond me.

de gustibus non disputandum, but on a unibus, there are also no
disputes because the bus master arbitrates

Better is to install a .profile that begins with 'unalias -a'.  That seems to clean out all the cruft and leave you with a clean slate to build from.

I've just learned to install my own .profile and .env files, and ignore the crap foisted on me by ... whatever ...

Colorized ls can show you other things.  For example:

* setuid/setgid files
* broken symlinks

ls -F can't do these.

Myself, I like ls itself to be colourless, but I do have an alias "cls"
and use it often.

Overall I guess it's more of a matter of, well, do you want Unix or do you 
want GNU?  On a desktop, I tend to find the GNU extensions useful.  On a 
server, I think I want lean and mean, minimalist, and more of a pure Unix 
environment.

Why wasting all the cycles for sourcing all this crap in the first place?
I know we have faster computers now, but still I do not want to load
something that is completely unnecessary, just so I can remove it later
with 'unalias'.

IMHO it is much cleaner to remove/rename all this, and then start with your
own scripts.

I happen to still work a lot on hardware monochrome terminals connected
via serial -- it is noticably slower if color information is included in
the output...

I always hated color on UNIX.  Monochrome green/amber/white is perfectly
fine to me.

(In normal usage) unless you want your dot-directories as well,
there's always good ol' \ls -1d */, or even echo */ if you can live
with the entries being all on one line separated by just one space.
Works nicely in an interactive shell, but may be slightly too
unreliable for a script (in GNU bash, the exact behavior depends on
the globbing options such as dotglob; other shells might act
differently based on state too, I just am not too familiar with them).

Using \ls above because some people (including myself) already have
their ls aliased to a ls command that includes -F, which looks ugly
when used with -d */. If you aren't one of them, then maybe you don't
need the backslash.

Using echo has the bonus that it's very often built in to the shell,
so no external invocation is required.

I don't think I'd call find minimalistic anything. :-) Modern ls is
pretty bloated too (surprisingly enough, on my system, the binary for
find is only about twice the size of the binary for ls; 233,968 and
114,032 bytes, respectively, but that's not counting any libraries
they pull in dynamically), but ls is probably in the disk cache
already; echo's nice and lean, though...

Hi,

(This is to stop the terminal switching between its two screens so the
useful bit of the man page is hidden from view when you quit, even
though you then want to type based on its content.)

For vim, `set t_ti= t_te=' overrides the terminal's definition.
Or, have a ~/.terminfo/... compiled from the system's default but with
those entries blanked.  Then all commands are "fixed".
