linuxshell判斷文件是否存在？

1. test命令的-a參數(shù)可用于確定該文件是否存在于Linux shell中。它可以通過if結(jié)構(gòu)來判斷。

2. 帶~/T/塞洛·皮例如，要檢測此文件并將其刪除（如果存在），示例代碼如下：

fi

3。測試效果如下圖所示

代碼1:

如果[test-d folder name]那么

echo“文件夾存在！“

else

echo”文件夾不存在！“

fi

代碼2:

test-d文件夾&；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp；amp
