linux uses if to determine whether a file exists

We can use the Linux shell to determine whether a file exists. Let’s take a look.

1. Create a new a.sh file

#这里的-f参数判断/home/abc.log是否存在
if [ -f "/home/abc.log" ]; then  
　　echo "文件存在"
else
    echo "文件不存在"
fi

2. Grant execution permission to the script

chmod +x a.sh

3. Run the script

./a.sh
