按包含小数的名称对文件进行排序

Question

I have 200 files in my folder that I would like to sort by name. Here is a short list of my files according to the way that my Linux computer sorted them by default.

Name at 0.2142.png
Name at 0.4284.png
Name at 0.04284.png
Name at 0.6426.png
Name at 0.8568.png
Name at 0.08568.png
...

I would like to resort them by name from lowest to highest, so my list would become

Name at 0.04284.png
Name at 0.08568.png
...
Name at 0.2142.png
Name at 0.4284.png
Name at 0.8568.png 
...

(I put elipses in the middle of my list because there are many more files between Name at 0.08568.png and Name at 0.2142.png.)

I'm still new to writing bash files but I would think I could write one to sort my figures.

Thanks

Addendum:

Since the file names are so long I abbreviated them as Name at... The real file name is Planetary Vorticity Tilting by Radial Velocity at t = with a number at the end. I hope you can understand why I didn't put that in the original question. I'm also pretty sure I said in the comments below that I am new to Linux and Ubuntu, I do not know "how" the file listing is created. I have a MatLab code that makes png files based off of my CFD data with the name that I provided above and the appropriate time step. When I open the folder on the Linux computer the files are automatically sorted in the way I listed above and I have no idea why.

If there is any other clarification needed I would be happy to put it here.

Answer 1

Given:

$ echo "$files"
Name at 0.2142.png
Name at 0.4284.png
Name at 0.04284.png
Name at 0.6426.png
Name at 0.8568.png
Name at 0.08568.png
Name at 1.11.png

You can do:

$ echo "$files" | sort -t.  -k1
Name at 0.04284.png
Name at 0.08568.png
Name at 0.2142.png
Name at 0.4284.png
Name at 0.6426.png
Name at 0.8568.png
Name at 1.11.png

That assumes the prefix Name at is the same in all cases.
