bash的大括号扩展问题

hzsjx

Bash Reference Manual中有这么一段描述大括号扩展的：
A sequence expression takes the form {x..y[incr]}, where x and y are either integers or single characters, and incr, an optional increment, is an integer. When integers are supplied, the expression expands to each number between x and y, inclusive. Supplied integers may be prefixed with ‘0’ to force each term to have the same width. When either x or y begins with a zero, the shell attempts to force all generated terms to contain the same number of digits, zero-padding where necessary.

但是实际操作下来却没有用“0”填充，还有增量设置好像也不行，哪位高手知道原因？

附我测试结果：
dts@ubuntu1:~$ echo {01..15}
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

ywlscpl

以本机bash版本的为准吧，可能版本不同就不支持

man bash 搜索\{.*\.\..*\}

ghp268

我的好像也不支持incr,pad 0倒是可以

1. echo {01..10}
   
2. 01 02 03 04 05 06 07 08 09 10

非常感谢ywlscpl，果然是版本问题
