Question

我的第二个“其他如果”不起作用。如果文件不存在，我无法下载文件。我不知道我在这里做错了什么。

#!/bin/bash
# upper case
file_upper_case=/root/MASTER.txt
# lower case
file_lower_case=/root/master.txt

if [ -e "$file_upper_case" ]; then
    echo "File is upper-case"
    echo "Changed to lower_case"
    mv $file_upper_case $file_lower_case
    chmod 664 $file_lower_case
    chown root.dba $file_lower_case

else if [ -e "$file_lower_case" ]; then
    echo "File is lower_case"
    echo "Change permission only"
    chmod 664 $file_lower_case
    chmod root.dba $file_lower_case

else if [ -e "$file_lower_case"]; then
    echo "File does not exist"
    echo "Create master.txt file"
   # Download master.txt file
    wget --no-check-certificate https://github.com/userid/bin/raw/master.txt -P /root
    chmod 664 /root/master.txt
    chown root.dba /root/master.txt
fi; fi

你可能想要这个（已测试）：

#!/bin/bash

file_upper_case=/root/MASTER.txt
file_lower_case=/root/master.txt

if [ -e "$file_upper_case" ]; then
    echo "File is upper-case"
    echo "Changed to lower_case"
    mv $file_upper_case $file_lower_case
    chmod 664 $file_lower_case
    chown root.dba $file_lower_case
elif [ -e "$file_lower_case" ]; then
    echo "File is lower_case"
    echo "Change permission only"
    chmod 664 $file_lower_case
    chmod root.dba $file_lower_case
else
    echo "File does not exist"
    echo "Create master.txt file"
    # Download master.txt file
    wget --no-check-certificate https://github.com/userid/bin/raw/master.txt -P /root
    chmod 664 /root/master.txt
    chown root.dba /root/master.txt
fi

您可以使用elif代替else if。此外，你错过了最后一个条件中的空格。
