And I need grep only folders with date names like "2011-08-05_03-01-15" I tried ls | grep '201' but in output comes 201 folder to
我只需要 grep 日期名称为“2011-08-05_03-01-15”的文件夹我试过 ls | grep '201' 但在输出中有 201 文件夹到
way with ls | grep '2011' is do not acceptable, because it is a hardcode.
与 ls 的方式 | grep '2011' 是不可接受的，因为它是硬编码。

You can do that without grep:
你可以在没有 grep 的情况下做到这一点：
ls -d ????-??-??_??-??-??
This works fine assuming you don't have other folder names following the same pattern without being dates, like aaaa-bb-cc_dd-ee-ff, as those will also be listed by the above command.
假设您没有遵循相同模式的其他文件夹名称而不是日期，aaaa-bb-cc_dd-ee-ff这将正常工作，例如，因为上面的命令也会列出这些名称。
You can even be less restrictive and list everything that has a -on the 5th position:
你甚至可以不那么严格，列出所有-在第 5 位有 的东西：
ls -d ????-*

With grep:
与grep：
ls -d */ | grep -E '[0-9]{4}(-[0-9]{2}){2}_([0-9]{2}-){2}[0-9]{2}'
With find:
与find：
find * -regextype posix-extended \
-regex '[0-9]{4}(-[0-9]{2}){2}_([0-9]{2}-){2}[0-9]{2}' \
-type d

ls | egrep '^[0-9]{4}-[0-9]{2}-[0-9]{2}_[0-9]{2}-[0-9]{2}-[0-9]{2}$'

Try with regExp:
尝试使用正则表达式：
ls | grep -E "....--_*--"
ls | grep -E "....- -_*- -"
