我正在尝试设置一个脚本完成运行后将持续存在的环境变量。在我结束 ssh 会话后它会消失。
示例 bash 脚本:
# User picks an option
1) export dogs = cool
2) export dogs = not_cool
运行脚本source script.sh
不起作用,因为它在运行时将我踢出我的外壳,并且还需要交互式菜单,因此它不起作用。基本上我希望用户能够选择一个选项来在他们的 shell 中的环境变量之间切换。这甚至可能吗?
资源:
#!/bin/bash
set -x
show_menu(){
NORMAL=`echo "\033[m"`
MENU=`echo "\033[36m"` #Blue
NUMBER=`echo "\033[33m"` #yellow
FGRED=`echo "\033[41m"`
RED_TEXT=`echo "\033[31m"`
ENTER_LINE=`echo "\033[33m"`
echo -e "${MENU}*********************************************${NORMAL}"
echo -e "${MENU}**${NUMBER} 1)${MENU} Option 1 ${NORMAL}"
echo -e "${MENU}**${NUMBER} 2)${MENU} Option 2 ${NORMAL}"
echo -e "${MENU}*********************************************${NORMAL}"
echo -e "${ENTER_LINE}Please enter a menu option and enter or ${RED_TEXT}enter to exit. ${NORMAL}"
read opt
}
function option_picked() {
COLOR='\033[01;31m' # bold red
RESET='\033[00;00m' # normal white
MESSAGE=${@:-"${RESET}Error: No message passed"}
echo -e "${COLOR}${MESSAGE}${RESET}"
}
