Question

当我打开终端获取错误消息时。错误信息是：

bash：/home/sea/.bashrc：第176行：语法错误：意外的文件结尾

这是我的.bashrc最后一个代码块：

case "$TERM" in
xterm*|rxvt*)
    PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\$(print_title)\a\]$PS1"
    __el_LAST_EXECUTED_COMMAND=""
    print_title () 
    {
        __el_FIRSTPART=""
        __el_SECONDPART=""
        if [ "$PWD" == "$HOME" ]; then
            __el_FIRSTPART=$(gettext --domain="pantheon-files" "Home")
        else
            if [ "$PWD" == "/" ]; then
                __el_FIRSTPART="/"
            else
                __el_FIRSTPART="${PWD##*/}"
            fi
        fi
        if [[ "$__el_LAST_EXECUTED_COMMAND" == "" ]]; then
            echo "$__el_FIRSTPART"
            return
        fi
        #trim the command to the first segment and strip sudo
        if [[ "$__el_LAST_EXECUTED_COMMAND" == sudo* ]]; then
            __el_SECONDPART="${__el_LAST_EXECUTED_COMMAND:5}"
            __el_SECONDPART="${__el_SECONDPART%% *}"
        else
            __el_SECONDPART="${__el_LAST_EXECUTED_COMMAND%% *}"
        fi 
        printf "%s: %s" "$__el_FIRSTPART" "$__el_SECONDPART"
    }
    put_title()
    {
        __el_LAST_EXECUTED_COMMAND="${BASH_COMMAND}"
        printf "\033]0;%s\007" "$1"
    }

    # Show the currently running command in the terminal title:
    # http://www.davidpashley.com/articles/xterm-titles-with-bash.html
    update_tab_command()
    {
        # catch blacklisted commands and nested escapes
        case "$BASH_COMMAND" in 
            *\033]0*|update_*|echo*|printf*|clear*|cd*)
            __el_LAST_EXECUTED_COMMAND=""
                ;;
            *)
            put_title "${BASH_COMMAND}"
            ;;
        esac
    }
    preexec_functions+=(update_tab_command)
    ;;
*)

最后一行是第175行。并且说第176行的错误消息有语法错误。我不知道bash语言，我想修复它。

顺便问一下，我应该学习bash语言的基本原理吗？

添加第176和177行：

true ;;
esac

我的bashrc有语法错误，我不知道如何解决它
