如果我运行以下命令:
find . -name "*.jar" -type f -ctime +1
我没有得到任何结果,而如果我运行:
find . -name "*.jar" -type f -ctime 1
我得到结果。
答案1
这意味着目录中的所有 jar 文件在不到 48 小时前都有状态更改。
详细解释
根据find
手册页,
-ctime n
File's status was last changed n*24 hours ago.
和 ...
When find figures out how many 24-hour periods ago the file was
last accessed, any fractional part is ignored, so to match -atime +1,
a file has to have been accessed at least two days ago.
而其他地方...
+n for greater than n
因此-ctime +1
意味着文件状态必须至少在 48 小时前发生更改。
