tar -czvf name-of-archive.tar.gz /path/to/directory-or-file
Here’s what those switches actually mean:

-c: Create an archive.
-z: Compress the archive with gzip.
-v: Display progress in the terminal while creating the archive, also known as “verbose” mode. The v is always optional in these commands, but it’s helpful.
-f: Allows you to specify the filename of the archive.

tar -czvf archive.tar.gz /home/ubuntu --exclude=/home/ubuntu/Downloads --exclude=/home/ubuntu/.cache
tar -czvf archive.tar.gz /home/ubuntu --exclude=*.mp4

Laravel  手动返回错误码
 
 
设想到一个情景，如果新增数据库时用户提交的数据正确，也就是通过了验证，但是添加数据库时发生错误，比如：

if(!$users->save()){
    //新增数据库时发生错误
}

那么需要返回错误信息，这个时候怎么手动呢？找到了一个函数，特此记录，感觉够用了：

xiaoysh8

<script>
    var _token = '{{csrf_token()}}';
    $.ajaxSetup({
        headers: {
            'X-CSRF-TOKEN': _token
        }
    });
</script>

 接下来就可以把错误信息提取出来了。
