How to find only a specific name on the disk?

How to find only a specific name on the disk.
The name is unique because it contains only a "dot"
Filename:

Code: Select all

.

Code: Select all

..ext

I tested a lot of different regular expressions, but none of them work correctly.

[HolgerK]

Code: Select all

^\.\..*

[makinero]

Code: Select all

^\.\..*

Incorrect regex!!, I want to find only "."

..ext

[HolgerK]

Correct regex syntax!
Incorrect problem description!
A filename with dot only and without extension is not a valid filename!

Maybe one of your tools you used to create such a filename is also able to find this file?

[makinero]

Your Regex just does not match what I'm looking for.
File name with dot (correct)
The file contains the extension (correctly)
I already have the correct regex and everything works.
Example:

..csv
..mp3
..jpg

Many people and you suggested incorrect regex on another forum, but someone finally gave the correct regex

[HolgerK]

Yes, your are the one and only...
BTW: "..csv" will also find "a.csv", "b.csv", "c.csv",..., "zzcsv" and so on.

One of your funny postings again.
If you already have the correct regex why do you spam this forum.

@Horst.Epp - I just asked a question on several forums at the same time. And one of the forums I got was wanted. What's funny about that?
Solved.

@HolgerK - You regex wrong ^\.\..*
Show me the screenshoot that shows the expected file names (dot). Of course, your regex will not show only dotted names.
Writing the correct expression causes many problems with understanding that I am looking for a name in the form of only a dot, which of course is possible in Windows.

The found names have only a single dot but the full filename has a extension like csv, jpg, mp3:

and out... this is just ridiculous...

We are not here to provide you lazy guy with every solution to any problem without a clear description from you what's going wrong in your case.
Feel free to refine the solution yourself to match all conditions on your system. e.g.:

Code: Select all

^\.\.\w{3}$

But this may imply that you have to learn the syntax and possibilities of regex by your own.

[makinero]

Code: Select all

^\.\.\w{3}$

Works according to the expected result.
