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 + +18. I start tcsh and it takes a couple of minutes to get the prompt. + You have defined REMOTEHOST and your DNS is not responding. Either + undefine REMOTEHOST and recompile or fix your DNS. + +19. If you need help generating your .cshrc file, check out: + http://www.imada.ou.dk/~blackie/dotfile/ + +20. On POSIX systems the kernel will send hup signals to all the processes + in the foreground process group if 'stty hupcl' is set. For example + ./tcsh + echo $$ + 591 + ./tcsh + kill -6 591 + + Will kill everything, since hup will be sent to all tcsh processes. + To avoid that you can set stty -hupcl, but it is not recommended. + +21. When I rsh the meta key stops working on the remote machine. + + Try using rsh -8; this option is undocumented on some systems, + but it works. If that does not work, get and use ssh/sshd. You'll + be better off from a security point of view anyway. + +22. Tcsh compiled under hp/ux-10.x does not pass resource limits correctly + when ran on hp/ux-11.x systems. This is a problem with lack of ABI + compatibility between the two systems. The only solution is to recompile. + +christos + +Everything else is a bug :-( |
