I really like the colored manpages which can are achieved by
export LESS_TERMCAP_mb=$'\E[01;31m'
export LESS_TERMCAP_md=$'\E[01;31m'
export LESS_TERMCAP_me=$'\E[0m'
export LESS_TERMCAP_se=$'\E[0m'
export LESS_TERMCAP_so=$'\E[01;44;33m'
export LESS_TERMCAP_ue=$'\E[0m'
export LESS_TERMCAP_us=$'\E[01;32m'
in your .bashrc or .zshrc. My question is: How do I export these variables in tcsh? I have to use tcsh at work and cannot get it working. I tried plenty of variations, but nothing worked. Simply replacing export with setenv and = with " " doesn't do the trick. But it should work somehow. If i start a tcsh out of my zsh with this exports set I can enjoy colored manpages in tcsh, also. But that's an ugly workaround.
The problem is that tcsh isn't interpreting the escape sequence in your variable name, so the environment variable ends up with a literal \E in it when you try to set it with tcsh. Here's one way you can get around that, using Bash to interpret the escape sequences, although it's a little ugly:
% setenv LESS_TERMCAP_md `bash -c 'echo -en "\e[01;31m"'`
% setenv LESS_TERMCAP_me `bash -c 'echo -en "\e[0m"'`
% setenv LESS_TERMCAP_se `bash -c 'echo -en "\e[0m"'`
% setenv LESS_TERMCAP_so `bash -c 'echo -en "\e[01;44;33m"'`
% setenv LESS_TERMCAP_ue `bash -c 'echo -en "\e[0m"'`
% setenv LESS_TERMCAP_us `bash -c 'echo -en "\e[01;32m"'`
