晚上回来骑脖子, 我在下面跳, 他在上面笑的咯咯叫. 放下面就哭,还要上去.

跳着跳着, 碰下巴了. 嗷嗷哭, 不上去了. 哭着要去找妈妈.

Grep Command Returns Grep Invalid Option
报错如下：
```
grep: invalid option -- '='
Usage: grep [OPTION]... PATTERN [FILE]...
Try grep --help for more information.`
```
答案：

In case this isn’t yet fixed, see if there is any file in the directory that starts with a ‘-‘.

李好李焕英
每天行尸走肉的生活，让我不敢看会流泪的电影，像一根针会扎痛自己，不想不敢扎痛自己，就想着看看爆米花电影打发时间好了。还好昨天被迫跟着去看了你好李焕英，挺好，又可以不再行尸走肉两天了。

Du Xfs_quota Not Match
https://unix.stackexchange.com/questions/156897/why-does-du-and-quota-results-not-match

I believe there may be some files still held open by some processes. You can try to list them using,

lsof | grep username | grep deleted A more better version would be to use,

lsof +L1 grep username

Make Setting Variables
If you’d like a variable to be set to a value only if it’s not already set, then you can use the shorthand operator ‘?=’ instead of ‘=’.
