How to sort strings that contain a common prefix and suffix numerically from Bash?
提问by AWE
Here is a list of files:
以下是文件列表：
some.string_100_with_numbers.in-it.txt
some.string_101_with_numbers.in-it.txt
some.string_102_with_numbers.in-it.txt
some.string_23_with_numbers.in-it.txt
some.string_24_with_numbers.in-it.txt
some.string_25_with_numbers.in-it.txt
Now I would like to sort it numerically. Starting with *23* and ending with *102*.
现在我想按数字对它进行排序。以 *23* 开头，以 *102* 结尾。
I have tried -nand -g. -tdoes not help in these messy strings.
我试过-n和-g。-t对这些凌乱的字符串没有帮助。
Can I ignore leading strings to the number with an option or do I have to be clever and script?
我可以使用选项忽略数字的前导字符串还是我必须聪明和脚本？

From the man page:
从手册页：
-v natural sort of (version) numbers within text

In the general case, try the Schwartzian transform.
在一般情况下，请尝试施瓦兹变换。
Briefly, break out the number into its own field, sort on that, and discard the added field.
简而言之，将数字分解到其自己的字段中，对其进行排序，然后丢弃添加的字段。
# In many shells, use ctrl-v tab to insert a literal tab after the first
sed 's/^\([^0-9]*\)\([0-9][0-9]*\)/ /' file |
sort -n |
cut -f2-
This works nicely if the input doesn't have an obvious separator, like for the following input.
如果输入没有明显的分隔符，这会很好地工作，例如以下输入。
abc1
abc10
abc2
where you would like the sort to move the last line up right after the first.
您希望排序在第一行之后将最后一行向上移动。

If available, simply use sort -V. This is a sort for version numbers, but works well as a "natural sort" option.
如果可用，只需使用sort -V. 这是对版本号的排序，但作为“自然排序”选项效果很好。
$ ff=$( echo some.string_{100,101,102,23,24,25}_with_numbers.in-it.txt )
Without sort:
无排序：
$ for f in $ff ; do echo $f ; done
some.string_100_with_numbers.in-it.txt
some.string_101_with_numbers.in-it.txt
some.string_102_with_numbers.in-it.txt
some.string_23_with_numbers.in-it.txt
some.string_24_with_numbers.in-it.txt
some.string_25_with_numbers.in-it.txt
With sort -V:
使用排序 -V：
$ for f in $ff ; do echo $f ; done | sort -V
some.string_23_with_numbers.in-it.txt
some.string_24_with_numbers.in-it.txt
some.string_25_with_numbers.in-it.txt
some.string_100_with_numbers.in-it.txt
some.string_101_with_numbers.in-it.txt
some.string_102_with_numbers.in-it.txt
