- This is for people who do not read the manual!
-
- So far people who don't read manuals don't read this either... I may
- call it README.*PLEASE* in the future, but then the same people won't
- be able to get ftp it... :-)
-
- 1. Why is the meta key broken in tcsh-5.20 and up?
-
- On some machines the tty is not set up to pass 8 bit characters by default.
- Tcsh 5.19 used to try to determine if pass8 should be set by looking at
- the terminal's meta key. Unfortunately there is no good way of determining
- if the terminal can really pass 8 characters or not. Consider if you are
- logged in through a modem line with 7 bits and parity and your terminal
- has a meta key. Then tcsh 5.19 would set wrongly set pass8.
-
- If you did like the previous behavior you can add in /etc/csh.login, or
- in .login:
-
- if ( $?tcsh && $?prompt ) then
- if ( "`echotc meta`" == "yes" ) then
- stty pass8
- endif
- endif
-
- If you don't have pass8, maybe something like
-
- stty -parity -evenp -oddp cs8 -istrip (rs6000)
- or
- stty -parenb -istrip cs8
-
- would work..
-
- 2. I ran 'dbxtool &' and 'shelltool &' from tcsh, and they end up in cbreak
- and no echo mode?
-
- These programs are broken. Background jobs should not try to look at the
- tty. What happens is that dbxtool looks in stderr to inherit the tty
- setups, but tcsh sets up the tty in cbreak and -echo modes, so that it
- can do line editing. This cannot be fixed because tcsh cannot give away
- the tty. A work-around is:
-
- dbxtool < /dev/null >& /dev/null &
- or
- /usr/etc/setsid dbxtool &
-
- If that does not work, for dbxtool at least you can add "sh stty sane"
- in your .dbxinit
-
- 3. I tried to compile tcsh and it cannot find <locale.h>?
-
- Your system does not support NLS. Undefine NLS in config_f.h and it
- should work fine.
-
- 4. Where can I get csh sources?
-
- Csh sources are now available with the 4.4BSD networking distributions.
- You don't need csh sources to compile tcsh-6.0x.
-
- 5. I just made tcsh my login shell, and I cannot ftp any more?
-
- Newer versions of the ftp daemon check for the validity of the
- user's shell before they allow logins. The list of valid login
- shells is either hardcoded or it is usually in a file called
- /etc/shells. If it is hard-coded, then you are out of luck and
- your best bet is to get a newer version of ftpd. Otherwise add
- tcsh to the list of shells. [For AIX this file is called
- /etc/security/login.cfg]. Remember that the full path is required.
- If there is no /etc/shells, and you are creating one, remember to
- add /bin/csh, /bin/sh, and any other valid shells for your system,
- so that other people can ftp too :-)
-
- 6. I am using SunView/OpenWindows and editing is screwed up. In
- particular my arrow keys and backspace don't work right. What
- am I doing wrong?
-
- Well, cmdtool tries to do its own command line editing and the
- effect you get is one of using an editor inside an editor. Both
- try to interpret the arrow key sequences and cmdtool wins since
- it gets them first. The solutions are in my order of preference:
-
- 1 Don't use suntools
- 2 Use shelltool instead of cmdtool.
- 3 Unset edit in tcsh.
-
- 6b. On a SPARCstation running Solaris 2.x and OpenWindows 3.1,
- inside a cmdtool, the short-cut key sequence to clear log
- (i.e. Meta-e or Diamond-e) doesn't work: it just echos 'e'
-
- 6c. On a SPARCstation running Solaris 2.x and OpenWindows 3.1,
- maketool (within SPARCworks) doesn't work: it just does
- a `cd' to the working directory then stops.
-
- The workaround for 6b and 6c is doing "unset edit."
- Using shelltool instead of cmdtool doesn't fix 6c.
-
- 7. I rlogin to another machine, and then no matter what I tell 'stty'
- I cannot get it to pass 8 bit characters?
-
- Maybe you need to use 'rlogin -8' to tell rlogin to pass 8
- bit characters.
-
- 8. Where do I get the public domain directory library?
-
- Anonymous ftp to prep.ai.mit.edu:/pub/gnu/dirent.tar.Z
-
- 9. I compiled tcsh using gcc, and when I start up it says:
- tcsh: Warning no access to tty (Invalid Argument).
- Thus no job control in this shell
-
- Your <sys/ioctl.h> file is not ansi compliant. You have one of 3 choices:
- a. Run fixincludes from the gcc distribution.
- b. Add -traditional to the gcc flags.
- c. Compile with cc.
-
- 10. I compiled tcsh with the SunOS unbundled compiler and now things
- get echo'ed twice.
-
- It is a bug in the unbundled optimizer. Lower the optimization level.
-
- 11. How can I use the arrow keys with hpterm?
- Hp terminals use the arrow keys internally. You can tell hpterm not
- to do that, by sending it the termcap sequence smkx. Since this
- has to be done all the time, the easiest thing is to put it as an
- alias for precmd, or inside the prompt:
-
- if ($term == "hp") then
- set prompt="%{`echotc smkx`%}$prompt"
- endif
-
- Note that by doing that you cannot use pgup and pgdn to scroll...
- Also if you are using termcap, replace "smkx" with "ks"...
-
- 12. On POSIX machines ^C and ^Z will do not work when tcsh is a login
- shell?
- Make sure that the interrupt character is set to ^C and suspend
- is set to ^Z; 'stty -a' will show you the current stty settings;
- 'stty intr ^C susp ^Z' will set them to ^C and ^Z respectively.
-
- 13. I am trying to compile tcsh and I am getting compile errors that
- look like:
-
- >sh.c:???: `STR???' undeclared, outside of functions [gcc]
- or
- >"sh.c", line ???: STR??? undefined [cc]
-
- You interrupted make, while it was making the automatically
- generated headers. Type 'make clean; make'
-
- 14. On the cray, sometimes the CR/LF mapping gets screwed up.
-
- You are probably logged in to the cray via telnet. Cray's
- telnetd implements line mode selection the telnet client
- you are using does not implement telnet line mode.
- This cause the Cray's telnetd to try to use KLUDGELINEMODE.
- You can turn off telnet line mode from the cray side by
- doing a "stty extproc", or you can get the Cray AIC to build
- a telnetd without KLUDGELINEMODE, or you can compile
- a new telnet client (from the BSD net2 tape), or at least
- on the suns use: 'mode character'.
-
-
- 15. On AU/X, I made tcsh my startup shell, but the mac desktop is not
- starting up (no X11 or Finder), and I only get console emulation.
-
- This is another manifestation of item 5. Just add the pathname
- to tcsh in /etc/shells and everything should work fine.
-
- 16. On machines that use YP (NIS) tilde expansion might end up in /dev/null
- If this happens complain to your vendor, to get a new version of NIS.
- You can fix that in tcsh by defining YPBUGS in config.h
-
- 17. Script on SGI 4.0.5 does not give us a tty, so we cannot have job
- control. Their csh does not have job control either. Try:
- % script
- % cat > /dev/tty
-
- christos
-
- Everything else is a bug :-(
