Difference between find . and find * in unix

问题

What is the difference between find . vs find * .

When i am trying to search for a file in current directory i.e. which was modified not more than 20 days ,i fired below query

find . -maxdepth 0 -mtime -20

The above command gives no output but

find * -maxdepth 0 -mtime -20

gives me the output that is required.Why is this happening i am searching in current directory only and . also means current directory

回答1:

. means "start with the current directory". A depth of 0 can only be ..

* means "start with the visible contents of the directory". A depth of 0 will be each of the visible items in the directory.

In addition to what @ignacio is correctly saying, you should also take into account that:

• find . looks for hidden files too, e.g. into the .git if there's one
• find * looks for the visible contents only within the directory
