I would welcome anyone to post a zsh configuration file even more
powerful than tcsh's /usr/doc/tcsh/examples/complete.tcsh

I'd give it a try if I didn't need to do the programming myself.

bash can't do it yet (as of version 2.01.1 or 2.02); however, according to
to their recent posting on comp.os.linux.announce:

A Peek at the Future


Things under consideration for bash-2.03 (or whatever the next version
is named) are

o An implementation of programmable completion for the bash
  readline interface

So, there is hope yet!  ;-)

I doubt you can. Not sure about the prompt, but bash doesn't have smart
filename completion. You could look at zsh, which is a ksh derivative with
all the above features.

bash can't, but zsh (a bourne shell derivative like bash) has programmable
completion that is even more powerful than what tcsh has.

sounds like most of the stuff i like ... i was just curious if there were
any really cool features of tcsh i'd been missing out on!

This is funny.  I just resisted the temptation to whine about operator
overloading in C++ in this thread. :)

unset autologout

Add it to your ~/.tcshrc or type in at the shell prompt.

Ugh...I shudder the thought.  I like C++  :)(although, I can

The correct name is "Korn," not "Kron."  Take a look at the man pages for
ksh.  :-)

this is one of the main motivators for me also.  the fact that bash comes
with just about everything, and is easily installed (or already installed
by the geek before you) on what's left.

again a good reason.  also the functionality of bash functions seems to
have well surpassed tcsh's aliases.

no kidding ... i learned on csh (sunos 4.1.1) ... talk about a horrible
experience ... it drove me to tcsh.

yack.  only program in sh/bash ... please.  it's so much nicer anyway i'm
not sure why anyone would want to write csh scripts.

yep.  a must read if you are tempted by the evil empire.

How 'bout I just tell you why I prefer bash these days.  (I'm not
interested in starting or participating in a "religious war" :)

I (only recently) have started to prefer bash over tcsh for two main
reasons:

1) I find myself working on several different OSs these days: WinNT,
Solaris, AIX, HP-UX, FreeBSD, Linux, etc.  Being able to have the same
shell everywhere is nice and I have found bash to be the easiest to
install on all these types of machines.  (autoconf is a beautiful
thing!)

2) Bash is Bourne Shell compatible.  This means that if I'm in a
situation where I cannot install bash, for whatever reason, I'm not
strangled by being unfamiliar with sh-flavor command line behavior.
(I've found that an unconfigured csh is about as friendly as
unconfigured ksh - both of which are found standard on most machines,
whereas bash and tcsh are usually only installed by people like me.)
This point is even stronger for scripts.  Very few scripts I find are
written in csh, so being familiar with Bourne syntax is more
productive.  (csh is supposed to be more "C-like" in it's syntax - I
find this very deceptive.  csh is about as C-like as French is
English-like.  Yes, there are similarities but they are very different
languages.  With bash around making sh as user-friendly as tcsh, I
might as well forget csh and learn sh.  (This is similar to why I
think Java/C can now replace C++, but I digress. :))

Of course this topic cannot be mentioned without the following
reference: http://language.perl.com/versus/csh.whynot

While there are still a few things I prefer about tcsh, I figure bash
can probably to it all, I just need to figure it out...  Reading the
rest of this thread just might be what I need!

Regards,
Keith

ps -  for those unfamiliar with the history of Unix shells:
  sh = Bourne Shell
  csh = C Shell (not sh compatible, a C-like shell)
  ksh = Kron Shell (an extension of sh)
  tcsh = Tenex(?) C shell (an extension of csh)
  bash = Bourne Again Shell (a sh compatible extension of sh with ksh,
 csh and tcsh functionality influence)
 LocalWords:  Kron

hmm, i'm didn't know that you could do all these things.  i use simple
file name completion all the time, but the below stuff is sorta neat.

where does it get the relevant suffix from?  /etc/mime.types?

this would be very cool as well.

how do you turn these features on?  they don't appear to be enabled by
default?

I much prefer tcsh for interactive use.  Having smart completion is the
best thing since sliced bread!

e.g.

$ cd [tab]  
 -> shows and completes to directory names only
$ latex [tab]
 -> shows and completes to .tex files only
$ emacs -[tab]
 -> shows and completes to available options for that command.

Who would want to live without it?
Can bash be taught to do this?  It would be great.

running a couple of days behind here but ...

are there reasons for your personal bias?  i definately agree with using
ssh for connecting to hosts (auto setting of display variable, encryption,
encrypted tunnelling of x sessions, rsa authentications etc etc).

is is there really any advantage to using bash over tcsh?

i use tcsh because it's what i learned first and now it's familiar... but
i've been looking for a reason to be bothered swapping over to bash.

can you convince me?  :)

I don't see how these two problems could be related but...

If your DISPLAY is not being set for local xterms make sure you are
setting it using "setenv" instead of "set" in your login shell.  For
remote xterms, look into the REMOTEHOST environment variable.


  Use bash (instead of tcsh) and ssh (for connecting to remote hosts).
