4 个解决方案

#1

ls|sort -V

The -V parameter ensures that chap10 is considered upper that chap9.

-V参数确保chap10被认为是chap9的上限。

#2

GNU ls has a version sort built-in:

GNU ls内置了一个版本排序:

ls -lv

#3

If you have ruby(1.9.1+)

如果你有红宝石(1.9.1+)

ruby -e 'puts Dir["chap*pdf"].sort_by{|x|x[/\d+/].to_i}'

#4

Assuming that you want to rename the files so you don't have to keep sorting them later:

假设您要重命名文件,以便以后不必继续对它们进行排序:

for f in chap*-solutions.pdf; do num=`echo $f | grep -o "[0123456789]\+"`; two_num=`printf "%02d" $num`; mv $f chap$two_num-solutions.pdf; done

grep -o "[0123456789]+" outputs the chapter number (one or two digits)

grep -o“[0123456789] +”输出章节号(一位或两位数)

printf returns a string that contains the zero-padded number

printf返回包含零填充数字的字符串

#1

ls|sort -V
