Rofi MPD控制脚本报错：第107行语法错误意外文件结束

你的脚本报错是因为**rofi_cmd()函数中rofi命令的最后一行多了一个反斜杠\**，这个反斜杠会让shell认为命令尚未结束，将下一行的函数闭合符}当作rofi的参数处理，导致函数无法正确闭合，最终触发"unexpected end of file"语法错误。

修复后的完整脚本 #

#!/usr/bin/env bash

## Music Player Controls

#Finally, the actual command.

}

# Pass variables to rofi dmenu
run_rofi() {
    echo -e "$option_1\n$option_2\n$option_3\n$option_4\n$option_5\n$option_6" | rofi_cmd
}

# Execute Command
run_cmd() {
    if [[ "$1" == '--opt1' ]]; then
        mpc -q toggle && notify-send -u low -t 1000 " `mpc current`"
    elif [[ "$1" == '--opt2' ]]; then
        mpc -q stop

    elif [[ "$1" == '--opt5' ]]; then
        mpc -q repeat
    elif [[ "$1" == '--opt6' ]]; then
        mpc -q random
    fi
}

关键修复点 #

将rofi_cmd()函数中rofi命令的最后一行-theme "$theme" \末尾的反斜杠删除，改为-theme "$theme"，确保函数能正确闭合，shell可以正常解析后续代码。
