1. ls mysql-bin.0000{13..26} 1>/dev/null

No need to code.

/home/lee/test#echo 'mysql-bin.000013
> mysql-bin.000014
> mysql-bin.000015
> mysql-bin.000016
> mysql-bin.000017
> mysql-bin.000018
> mysql-bin.000019
> mysql-bin.000021
> mysql-bin.000022
> mysql-bin.000023
> mysql-bin.000024
> mysql-bin.000025
> mysql-bin.000026'|xargs -i touch {}
/home/lee/test#ls mysql-bin.0000{13..26} 1>/dev/null
ls: mysql-bin.0000{13..26}: 没有那个文件或目录
/home/lee/test#

You can also use a slightly different type of brace expansion for creating a sequence of letters or numbers. If you type echo {2..5} you'll see this expands to 2 3 4 5. Typing echo {d..h} results in the expansion d e f g h.[11]

[11] This form of brace expansion is not available in bash prior to Version 3.0.
