This is tcsh version 6.09. 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) make
|
|
|
|
7) 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.
|
|
|
|
8) 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.
|
|
|
|
9) 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...
|
|
|
|
10) Enjoy.
|
|
|
|
11) PLEASE send any bug reports (and fixes), code for new features,
|
|
comments, questions, etc. (even flames) to:
|
|
|
|

On sysv versions < 3.0 (not hpux) Doug Gwyn's public domain directory

On BSDreno, in ttyname() closedir() is called twice and so the same

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
