8 For the people who do not read the manual!
10 Why is the meta key broken in tcsh-5.20 and up?
12 On some machines the tty is not set up to pass 8 bit characters by
13 default. Tcsh 5.19 used to try to determine if pass8 should be set by
14 looking at the terminal's meta key. Unfortunately there is no good way
15 of determining if the terminal can really pass 8 characters or not.
16 Consider if you are logged in through a modem line with 7 bits and
17 parity and your terminal has a meta key. Then tcsh 5.19 would set
20 If you did like the previous behavior you can add in /etc/csh.login, or
22 if ( $?tcsh && $?prompt ) then
23 if ( "`echotc meta`" == "yes" ) then
28 If you don't have pass8, maybe one of these would work:
29 stty -parity -evenp -oddp cs8 -istrip (rs6000)
30 stty -parenb -istrip cs8
32 Finally, tcsh will bind all printable meta characters to the self
33 insert command. If you don't want that to happen (i.e. use the
34 printable meta characters for commands) setenv NOREBIND.
36 I ran dbxtool & and shelltool & from tcsh, and they end up in cbreak and no
39 These programs are broken. Background jobs should not try to look at
40 the tty. What happens is that dbxtool looks in stderr to inherit the
41 tty setups, but tcsh sets up the tty in cbreak and -echo modes, so that
42 it can do line editing. This cannot be fixed because tcsh cannot give
43 away the tty. Pick one of the following as a workaround:
44 dbxtool < /dev/null >& /dev/null &
45 /usr/etc/setsid dbxtool &
47 If that does not work, for dbxtool at least you can add sh stty sane in
50 I tried to compile tcsh and it cannot find <locale.h>?
52 Your system does not support NLS. Undefine NLS in config_f.h and it
55 Where can I get csh sources?
57 Csh sources are now available with the 4.4BSD networking distributions.
58 You don't need csh sources to compile tcsh-6.0x.
60 I just made tcsh my login shell, and I cannot ftp any more?
62 Newer versions of the ftp daemon check for the validity of the user's
63 shell before they allow logins. The list of valid login shells is
64 either hardcoded or it is usually in a file called /etc/shells. If it
65 is hard-coded, then you are out of luck and your best bet is to get a
66 newer version of ftpd. Otherwise add tcsh to the list of shells. (For
67 AIX this file is called /etc/security/login.cfg.) Remember that the
68 full path is required. If there is no /etc/shells, and you are creating
69 one, remember to add /bin/csh, /bin/sh, and any other valid shells for
70 your system, so that other people can ftp too.
72 I am using SunView or OpenWindows and editing is screwed up. In particular my
73 arrow keys and backspace don't work right. What am I doing wrong?
75 Well, cmdtool tries to do its own command line editing and the effect
76 you get is one of using an editor inside an editor. Both try to
77 interpret the arrow key sequences and cmdtool wins since it gets them
78 first. The solutions are in my order of preference:
80 * Use shelltool instead of cmdtool.
83 On a SPARCstation running Solaris 2.x and OpenWindows 3.1, inside a cmdtool,
84 the short-cut key sequence to clear log (i.e. Meta-e or Diamond-e) doesn't
85 work: it just echos ‘e’; or
89 On a SPARCstation running Solaris 2.x and OpenWindows 3.1, maketool (within
90 SPARCworks) doesn't work: it just does a `cd’ to the working directory then
93 Unset edit in tcsh. Using shelltool instead of cmdtool does not fix
96 I rlogin to another machine, and then no matter what I tell stty I cannot get
97 it to pass 8 bit characters?
99 Maybe you need to use rlogin -8 to tell rlogin to pass 8 bit
102 Where do I get the public domain directory library?
104 Anonymous ftp to ftp://prep.ai.mit.edu/pub/gnu/dirent.tar.Z
106 I compiled tcsh using gcc, and when I start up it says: tcsh: Warning no
107 access to tty (Invalid Argument). Thus no job control in this shell
109 Your <sys/ioctl.h> file is not ansi compliant. You have one of 3
111 * Run fixincludes from the gcc distribution.
112 * Add -traditional to the gcc flags.
115 I compiled tcsh with the SunOS unbundled compiler and now things get echoed
118 It is a bug in the unbundled optimizer. Lower the optimization level.
120 How can I use the arrow keys with hpterm?
122 Hp terminals use the arrow keys internally. You can tell hpterm not to
123 do that, by sending it the termcap sequence smkx. Since this has to be
124 done all the time, the easiest thing is to put it as an alias for
125 precmd, or inside the prompt:
126 if ($term == "hp") then
127 set prompt="%{`echotc smkx`%}$prompt"
130 Note that by doing that you cannot use pgup and pgdn to scroll… Also if
131 you are using termcap, replace smkx with ks.
133 On POSIX machines ^C and ^Z do not work when tcsh is a login shell?
135 Make sure that the interrupt character is set to ^C and suspend is set
136 to ^Z; stty -a will show you the current stty settings; stty intr ^C
137 susp ^Z will set them to ^C and ^Z respectively.
139 I am trying to compile tcsh and I am getting compile errors that look like:
141 sh.c:???: `STR???' undeclared, outside of functions [gcc]
142 "sh.c", line ???: STR??? undefined [cc]
144 You interrupted make, while it was making the automatically generated
145 headers. Type make clean; make
147 On the cray, sometimes the CR/LF mapping gets screwed up.
149 You are probably logged in to the cray via telnet. Cray's telnetd
150 implements line mode selection the telnet client you are using does not
151 implement telnet line mode. This cause the Cray's telnetd to try to use
152 KLUDGELINEMODE. You can turn off telnet line mode from the cray side by
153 doing a stty -extproc, or you can get the Cray AIC to build a telnetd
154 without KLUDGELINEMODE, or you can compile a new telnet client (from
155 the BSD net2 tape), or at least on the suns use: mode character.
157 On AU/X, I made tcsh my startup shell, but the mac desktop is not starting up
158 (no X11 or Finder), and I only get console emulation.
160 Add the pathname to tcsh in /etc/shells and everything should work
163 On machines that use YP (NIS) tilde expansion might end up in /dev/null
165 If this happens complain to your vendor, to get a new version of NIS.
166 You can fix that in tcsh by defining YPBUGS in config.h
168 Script on SGI 4.0.5 does not give us a tty, so we cannot have job control.
170 Their csh does not have job control either. Try:
174 I start tcsh and it takes a couple of minutes to get the prompt.
176 You have defined REMOTEHOST and your DNS is not responding. Either
177 undefine REMOTEHOST and recompile or fix your DNS.
179 If you need help generating your .cshrc file, check out:
181 * https://github.com/tcsh-org/tcsh/blob/master/dot.tcshrc
182 * https://github.com/tcsh-org/tcsh/blob/master/dot.login
184 On POSIX systems the kernel will send hup signals to all the processes in the
185 foreground process group if ‘stty hupcl’ is set.
194 Will kill everything, since hup will be sent to all tcsh processes. To
195 avoid that you can set stty -hupcl, but it is not recommended.
197 When I rsh the meta key stops working on the remote machine.
199 Try using rsh -8; this option is undocumented on some systems, but it
200 works. If that does not work, get and use ssh/sshd. You'll be better
201 off from a security point of view anyway.
203 Tcsh compiled under hp/ux-10.x does not pass resource limits correctly when
204 ran on hp/ux-11.x systems.
206 This is a problem with lack of ABI compatibility between the two
207 systems. The only solution is to recompile.
209 Refreshing in command line editing can appear broken on some OS's
211 This is because the termcap/terminfo description lies about the ability
212 of the terminal to use tabs. At least on Compaq/DEC Alpha OSF/1 3.x and
213 4.x systems, stty -tabs will cause problems.
215 Where can I learn the merits of tcsh vs. bash vs. csh vs. sh etc?
217 You can read the manual page section titled [NEW FEATURES] listing
218 features that tcsh adds to csh.
220 You can read Tom Christiansen's Csh Programming Considered Harmful, a
221 document advocating that csh (and by extension, tcsh) should not be
222 used for writing shell scripts.
224 XXX: Need to find something about bash, but bash is sh-compatible and
225 has many of the same interactive features of tcsh (command completion
226 does not appear to be as flexible, though).
228 Curtains up: introducing the Z shell has a pretty good rundown on zsh.
229 Aside from the arguments about csh being evil, tcsh appears to compare
230 well with zsh. Zsh is sh and ksh compatible, with many of the
231 interactive features of tcsh.
233 Why does FreeBSD's tcsh do history browsing differently than I expect?
235 On FreeBSD, by default, the up arrow is set to history-search-backward,
236 rather than the default up-history. As a result, if you type (part of)
237 a word and press up arrow, you'll see previous commands that match the
238 prefix. Pretty useful, actually, although it takes some getting used
239 to. You can use bindkey to see your settings, and to rebind up & down
240 differently if desired.
