Bash 真正的数字顺序包括负数？

Question

ls -v ./file* 按自然顺序对文件名进行排序:

file1.txt
file2.txt
file11.txt

但是如果我们包含负数，它会返回:

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

如何按自然顺序排序(包括负数)？

灵感来自Bash true numerical order

Answer 1

似乎有以下效果:

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

要测试，请执行以下操作:

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
