当名称是实数时，是否可以按数字对文件进行排序？

Question

我有一个文件，其名称是实数，包括正数和负数。我需要文件的数字顺序，比如 -1.0、-0.5、0.0、0.5、1.0 .... 来制作 animation from the files

我试过了

ls -v1 -- *.pgm

但结果是

0.000000.pgm
0.080000.pgm
0.160000.pgm
0.240000.pgm
0.320000.pgm
0.400000.pgm
0.480000.pgm

Answer 1

您正在寻找sort -g“一般数字排序”

mapfile -t sorted_files < <(printf '%s\n' *.pgm | sort -g)
declare -p sorted_files

当名称是实数时，是否可以按数字对文件进行排序？

Is it possibly to sort files numerically when names are real numbers?

bash

filenames

ls
