Bash true numerical order

Question

How can I order files in a directory by their true numeric order.

file1.txt
file2.txt
file11.txt
...

I think it\'s called : Natural Order

Answer 1

Use the -v option:

ls -v file*
file1
file2
file11
file12

Another option may be using sort -V, assuming that one is available on your platform:

ls file* |sort -V
