man帮助文件需要有颜色其实很简单下面是我的必备设置（追加到~/.bashrc文件中，然后直接source ~/.bashrc即可生效）# Set colors for man pagesman() {  env \  LESS_TERMCAP_mb=$(printf "\e[1;31m") \  LESS_TERMCAP_md=$(printf "\e[1;31m") \  LESS_TERMCAP_me=$(printf "\e[0m") \  LESS_TERMCAP_se=$(printf "\e[0m") \  LESS_TERMCAP_so=$(printf "\e[1;44;33m") \  LESS_TERMCAP_ue=$(printf "\e[0m") \  LESS_TERMCAP_us=$(printf "\e[1;32m") \  man "$@"}
