函数未被调用且脚本退出

RM_OBJ_P所以我得到了从菜单页面调用的函数PAGE_RM。这是有效的，您可以输入您知道的所有时髦文件名，如果它们在数据库中，则输出将打印到文本文件中（正如我想要的那样）。但如果我愚蠢地选择了应该调用的某种“神奇”选项x（或） ，脚本就会退出。我做错了什么？ （我也尝试通过使用而不是 来实现这一点）XPAGE_RM
return 0PAGE_RM

编辑：显然输入x作为选择也调用RM_P_*（参见添加的日志）

RM_OBJ_P() {
echo "After you have finished, you can find the file here: $ACTIVE_DB/remove.txt"
echo
if [ ! -f file.txt ] ; then
    read -p "Please enter the name of the file you'd like to check (or x to return): " CHOICE
    case "$CHOICE" in
        *) RM_P_N ;;
        x|X) PAGE_RM ;;
    esac
else
    read -p "Please enter the name of the file you'd like to check: " CHOICE
    echo "- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -" >>$ACTIVE_DB/remove.txt
    echo "If you want to remove $CHOICE, please consider this:" >>$ACTIVE_DB/remove.txt
    case "$CHOICE" in
        *) RM_P_E;;
        x|X) PAGE_RM ;;
    esac
fi
}

如果重要的话，RM_P_N并且RM_P_E都是这样的（并且按预期工作）

RM_P_*() {
echo "something gets an echo echo echo o o o" >file.txt
PATH/TO/perl_script.pl "$CHOICE" database_query >>file.txt
RM_OBJ_P
}

最后但并非最不重要，PAGE_RM

PAGE_RM() {
    clear
    while :; do
        PRINT_BANNER_S
        PRINT_RM_MENU
        echo "single - view"
        echo "print  - print"
        PRINT_LINE
        echo "x      - go back"
        PRINT_LINE3
        read -p "CHOICE: " CHOICE
            case "$CHOICE" in
                s|S) RM_OBJ ;;
                p|P) RM_OBJ_P ;;
                x|X) return 0
                PRINT_LINE
            esac
    done
}

这是日志的相关部分

+ RM_OBJ_P
+ echo 'After you have finished, you can find the file here: DB_45763/remove.txt'
+ echo
+ '[' '!' -f DB_45763/remove.txt ']'
+ read -p 'Please enter the name of the file you'\''d like to check: ' CHOICE
Please enter the name of the file you'd like to check: + echo '- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -'
+ echo 'If you want to remove x, please consider this:'
+ case "$CHOICE" in
+ RM_P_E
+ echo 'If you want to remove x, please consider this:'
+ ./files/perls/remove_object.pl x dbi:SQLite:dbname=test.sqlite '' ''

没关系，这样解决它
[在你（说话）问之前思考的好例子]。如果大家有更好的解决方案，欢迎回复

RM_OBJ_P() {
echo "After you have finished, you can find the file here: $ACTIVE_DB/remove.txt"
echo
if [ ! -f $ACTIVE_DB/remove.txt ] ; then
    read -p "Please enter the name of the file you'd like to check (x to abort): " CHOICE
    if [[ $CHOICE = x ]] ; then
        PAGE_RM
    else
        RM_P_N
    fi
else
    read -p "Please enter the name of the file you'd like to check (x to abort): " CHOICE
    echo "- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -" >>$ACTIVE_DB/remove.txt
    echo "If you want to remove $CHOICE, please consider this:" >>$ACTIVE_DB/remove.txt
    if [[ $CHOICE = x ]] ; then
        PAGE_RM
    else
        RM_P_E
   fi
fi
}
