Bash真正的數字順序包括負數？

Question

ls -v ./file*各種各樣的文件名中的自然順序：

file1.txt 
file2.txt 
file11.txt 

但如果我們有負數，它給予回覆：

file1.txt 
file2.txt 
file11.txt 
file-5.txt 
file-18.txt 

如何在自然順序包括負數排序？

通過Bash true numerical order

Answer 1

靈感似乎以下工作：

$ ls file*|sort -k1.5n #start sorting at character 5 
file-18.txt 
file-5.txt 
file1.txt 
file2.txt 
file11.txt 

要進行測試，這樣做：

echo "a black" > file-18.txt 
echo "e white" > file-5.txt 
echo "i red" > file1.txt 
echo "o green" > file2.txt 
echo "u blue" > file11.txt 
echo "voyelles" > file013.47.txt 
ls file*|sort -k1.5n #start sorting at character 5
