This is tcsh version 6.12. Tcsh is a version of the Berkeley
C-Shell, with the addition of: a command line editor, command and file
name completion, listing, etc. and a bunch of small additions to the
shell itself.
Tcsh has been ported to most unix variants, and can be tinkered to work
in unix systems that it has not ported yet. See the Ported file for
a more complete list of ported systems and in the config directory for
a configuration file that matches your system.
Tcsh also runs under VMS/POSIX and OS/2+emx; the OS/2 port is not
complete yet.
Feel free to use it. These changes to csh may only be included in a
commercial product if the inclusion or exclusion does not change the
purchase price, level of support, etc. Please respect the individual
authors by giving credit where credit is due (in other words, don't
claim that you wrote portions that you haven't, and don't delete the
names of the authors from the source code or documentation).
To install tcsh:
0) Try running "configure". If that works, goto step 6.
If you are using imake, try xmkmf and goto step 3.
If imake does not work, copy Makefile.std to Makefile.
1) Look at the Makefile and make sure that you are using the right
compilation flags.
2) Copy the appropriate for your machine and OS config file from the
config subdirectory into config.h. Consult the file "Ported" for
settings known to work on various machines. If you are trying to
compile tcsh on a machine for which there is no config file yet,
you will need to create a config file using as a template one of
the supplied ones. If you get tcsh working on a new machine, I'd
appreciate a copy of the config file plus additional information
about the architecture/OS. If you are creating a new config file,
look very hard at BSDJOBS, BSDSIGS, and BSDTIMES if you are running
a non-BSD machine. For vanila SysV, these would all be #undef-ed,
but others may vary (such as A/UX or HPUX). On a pyramid, compile
in the UCB universe even if you are running under the ATT universe
usually; it will work anyway, and you get job control for free.
3) Look at config_f.h, and enable or disable any features you want.
It is configured the way I like it, but you may disagree.
If you do not have NLS, then locale.h will not be found. Undefine it
and things should work ok. On the other hand, if you have NLS you
might as well use it...
4) Look at host.defs to make sure that you have the right defines to set
the environment variables "HOSTTYPE", "MACHTYPE", "OSTYPE" and
"VENDOR" correctly. If you need to make changes, PLEASE SEND THEM
BACK TO ME.
5) You may want to adjust the TCSH_BINDIR and TCSH_MANDIR entries in
the Makefile. These are the directories that tcsh, and the tcsh.1
man entry will be placed in when you do a "make install" and "make
install.man" respectively. If you decide to install tcsh somewhere
other than in /usr/local/bin/tcsh, you should #define _PATH_TCSHELL
"/your/installation/directory/tcsh" in pathnames.h.
6) If you've changed any of the configuration variables you may need
to re-run configure.
7) make
8) Read the documentation while you are waiting. The file tcsh.man
is in standard [nt]roff -man format. If you like, you can run the
tcsh.man2html script (requires Perl) to generate an HTML version of
the manpage which you can read with Mosaic, lynx or other HTML browser.
9) Test tcsh by typing ./tcsh to see that it has compiled correctly.
The history command should give a time stamp on every entry.
Typing normal characters should echo each exactly once. Control-A
should put the cursor at the beginning of the input line, but after
the prompt. Typing characters after that should insert them into
the line. If you have job control make sure that stopping and
restarting jobs works. Make sure you can ^C in the middle of the
input line. Also make sure that pipelines work correctly and there
are no races. Try 'echo | cat | cat | cat | cat | more' a couple of
times. If you have job control, try this command in the background
and bring it in the foreground when it stops for tty output. Also
make sure that the ioctl() modes are preserved. Get into vi, enter
and exit input mode and suspend it, background it and foreground it
again. After all that, lastly make sure that the tty process group
manipulation is happening correctly. Try ftp to some host. If your
passwd appears on the screen, you have lost /dev/tty. Otherwise
everything is fine.
10) Once satisfied that tcsh is working correctly, complete the installation
by typing "make install" to install the binary, and "make install.man" to
install the documentation. Don't forget to look at complete.tcsh for
useful completions...
11) Enjoy.
12) PLEASE send any bug reports (and fixes), code for new features,
comments, questions, etc. (even flames) to:
The tcsh mailing list

***************************************************************************
On sysv versions < 3.0 (not hpux) Doug Gwyn's public domain directory
manipulation library has to be installed. This library is available
for anonymous ftp from prep.ai.mit.edu:/pub/gnu/dirent.tar.Z
If the network is not installed, then there is a gethostname()
routine is tc.os.c, enabled by defining NEEDgethostname
***************************************************************************
On BSDreno, in ttyname() closedir() is called twice and so the same
pointer gets free'd twice. tcsh's malloc is picky and it prints an
error message to that effect. If you don't like the message:
1. Apply the following patch:
*** /usr/src/lib/libc/gen/ttyname.c.orig Fri Jun 1 17:17:15 1990
--- /usr/src/lib/libc/gen/ttyname.c Tue Oct 29 16:33:12 1991

break;
}

Or: Comment the error printing out in tc.alloc.c
Or: Compile -DSYSMALLOC

Tcsh has been ported to minix by Scott Krotz (krotz@honey.rtsg.mot.com).
Unfortunately the minix sed is broken, so you'll have to find a way to
make tc.const.h, sh.err.h, ed.defns.h which are automatically generated.
The easiest way to create them is to make a copy from unix, copying
minix to config.h, and then 'make sh.err.h tc.const.h ed.defns.h'
The OS/dependent files are in mi.termios.h, mi.wait.h, mi.varargs.h
You will get some warnings, but dont worry about them, just ignore
them. After tcsh has compiled and the gcc binary is converted to a
minix binary, remember to chmem it to give it more memory - it will
need it! How much you need depends on how many aliases you have, etc..
Add at least 50000 to it.
One last thing. You might have to make some links for include files so
that they are in the directories that tcsh is expecting while compiling.
I forget if I had to do this or not, but it should be fairly easy to sort
out. If it cant find any include files this is probably the reason.
If you have any problems, please tell me. I can be contacted through
e-mail at:
krotz@honey.rtsg.mot.com
I also read comp.os.minix on a regular basis, so a note there will get
my attention also.
Have fun!
ps. The termios functions are provided by Magnus Doell and Bruce Evans.
Thanks, guys!

This is for minix 1.5 (straight out of the box from P-H) plus the i386
patches from Bruce Evans.
I cross-compiled on a Sun using gcc 2.1 with a target of i386-bsd
(using the minix include files instead of the bsd versions), and then
linked the resulting object files with similarly compiled crtso.o and
libc.a on vax (little endian) using a hacked version of ld which I put
together to generate minix executables instead of bsd a.out format.
What a kludge ...
I compiled with -O2 -Wall ... So far I haven't noticed any problems
with the optimizer.
In case anyone is contemplating compiling tcsh with bcc (Bruce Evan's
i386 compiler that comes with the minix386 upgrade package), don't bother.
It is some serious bugs that kill tcsh when compiled for 16-bit characters.
I can provide more details of bugs that I noticed for brave souls who want
to try, but it would be hard (and why bother if you can get gcc?).
I can make the binary available to anyone who wants it (for example people
who can't get access to a cross-compiling environment, and who don't yet
have gcc running under minix).

If your compiler cannot handle long symbol names, add
#include "snames.h"
to your config.h file
