I have tried this also, but no difference in tcsh's behaviour. I have even tried editing termcap.src in /usr/src/share/termcap/ and doing a 'make install' there to see if I'm missing a step... but no luck. I also received an off-list tip from Karl Vogel: > I've noticed that both zsh and tcsh can get really snotty if the > environment variables are not set in this order: > > unsetenv TERMCAP > unsetenv TERMINFO > unsetenv TERM > setenv TERMCAP /path/to/your/termcap/file (or actual termcap entry) > setenv TERMINFO /path/to/your/terminfo/directory > setenv TERM xterm But neither TERMCAP nor TERMINFO are set in my normal tcsh environment. I have tried setting and unsetting them in the order given here and many other permutations, to no success. I have tried logging out and back in again, in case tcsh caches termcap somewhere that isn't updated without re-running tcsh, but I don't think this is the case. The only thing I haven't tried yet is rebooting - technically I don't think I would have to. Is there some utility somewhere that can tell me if I've got a typo in my termcap or something which would prevent tcsh from reading my new entry properly? I suppose could write my own curses program to do this... maybe. Is there some utility somewhere which will translate my termcap into terminfo so I can try that? Why is there no terminfo stuff in FreeBSD 4.8? -- Jim Ramsay
