edit_dict() #用户词典，可以直接调出该文档并编写，但是记得保存后重新加载一次分词引擎
这个就是内置调用字典的
你可以再work函数中有个参数好像叫user,可以自己用text写一列字典，用utf-8编码的，然后引用这个path就可以了
R中的列表类似于Python中的字典(dictionary)或者Peal中的哈希(hash)，但又有差别。其实R有一个叫做hash的包，可以实现与Python中的dic及Perl中的hash相同的功能。
R中的list与Python中dictionary的区别：
虽然看起来有点像，但R中的list与Python中的字典还是有很大差别的，主要体现在下面几个方面：
3.1 可以没有键名
hase是键值对，必须有键名，但R的list可以没有键名，默认键名为[[n]]，n为元素所在位置。
3.2 有序，且允许键值重复
这应该是R的list与Python中的dictionary最大的区别了。Peal中的hash及Python中dic的最大特点就是无序且键值唯一，这样在牺牲有序性的情况下保证了数据存取的高效性。但R中的list这两方面都不满足。其性能与hash及dic应该也有差别吧(没比较过)。
找到password requisite pam_cracklib.so在后面可以加 difok=x（要x个不同字符） minlen=x（最小密码长度） ucredit=-x（最少x个大写字母） lcredit=-x（最少x个小写字母） dcredit=-x （最少x个数字）dictpath=/usr/share/cracklib/pw_dict时间在[root@localhost ~]# vim /etc/login.defs，PASS_MAX_DAYS 99999 （最大什么时候过期）PASS_MIN_DAYS 0 （最小什么事后过期）PASS_MIN_LEN 5 （密码最小长度）PASS_WARN_AGE 7 （警告天数）我们在使用linux系统设置密码的时候，经常遇到这样的问题，系统提示：您的密码太简单，或者您的密码是字典的一部分。那么系统是如何实现对用户的密码的复杂度的检查的呢？系统对密码的控制是有两部分(我知道的)组成：
1 cracklib
2 login.defs
声明：login.defs主要是控制密码的有效期。对密码进行时间管理。此处不细谈login.defs --shadow password suite configuration，pam_cracklib.so 才是控制密码复杂度的关键文件
redhat公司专门开发了cracklib这个安装包来判断密码的复杂度可以rpm -ql cracklib查看
密码的复杂度的判断是通过pam模块控制来实现的，具体的模块是pam_cracklibpam_cracklib 的参数介绍：debug，This option makes the module write information to syslog(3) indicating the behavior of the module (this option does not write password information to the log file).
type=XXX，The default action is for the module to use the following prompts when requesting passwords: "New UNIX password: " and "Retype UNIX password: ". The default word UNIX can be replaced with this option. retry=N，Prompt user at most N times before returning with error. The default is 1 ，difok=N，This argument will change the default of 5 for the number of characters in the new password that must not be present in the old password. In addition, if 1/2 of the characters in the new password are different then the new password will be accepted anyway.
difignore=N，How many characters should the password have before difok will be ignored. The default is 23. minlen=N，The minimum acceptable size for the new password (plus one if credits are not disabled which is the default). In addition to the number of characters in the new password, credit (of +1 in length) is given for each different kind of character (other, upper, lower and digit). The default for this parameter is 9 which is good for a old style UNIX password all of the same type of character but may be too low to exploit the added security of a md5 system. Note that there is a pair of length limits in Cracklib itself, a "way too short" limit of 4 which is hard coded in and a defined limit (6) that will be checked without reference to minlen. If you want to allow passwords as short as 5 characters you should not use this module. dcredit=N(N >= 0) This is the maximum credit for having digits in the new password. If you have less than or N digits, each digit will count +1 towards meeting the current minlen value. The default for dcredit is 1 which is the recommended value for minlen less than 10.(N <0) This is the minimum number of digits that must be met for a new password.ucredit=N，(N >= 0) This is the maximum credit for having upper case letters in the new password. If you have less than or N upper case letters each letter will count +1 towards meeting the current minlen value. The default for ucredit is 1 which is the recommended value for minlen less than 10.(N >0) This is the minimum number of upper case letters that must be met for a new password.lcredit=N(N >= 0) This is the maximum credit for having lower case letters in the new password. If you have less than or N lower case letters, each letter will count +1 towards meeting the current minlen value. The default for lcredit is 1 which is the recommended value for minlen less than 10，(N <0) This is the minimum number of lower case letters that must be met for a new password.ocredit=N，(N >= 0) This is the maximum credit for having other characters in the new password. If you have less than or N other characters, each character will count +1 towards meeting the current minlen value. The default for ocredit is 1 which is the recommended value for minlen less than 10.(N <0) This is the minimum number of other characters that must be met for a new password.use_authtok，This argument is used to force the module to not prompt the user for a new password but use the one provided by the previously stacked password module. dictpath=/path/to/dic，Path to the cracklib dictionaries. dictpath=/path/to/dict //注：密码字典，这个是验证用户的密码是否是字典一部分的关键。
