Linux三剑客（grep、sed、awk）

原文：https://blog.csdn.net/sj349781478/article/details/82930982 下面所说的是Linux中最重要的三个命令在业界被称为“三剑客”，它们是awk,sed,grep。我们现在知道Linux下一切皆文件，对Linux的操作就是对文件的处理，那么怎么能更好的处理文件呢？这就要用到我们上面的三剑客命令。在说这三个命令前我们要插入一个小插曲就是“正则表达式”。一、正则表达式所谓的正则表达式我个人理解就是正规的表示方法。他是用简单的方法来实现强大的功能，所以深受计算机爱好者的使用。三剑客与正则表达式是什么关系呢？我们可以这样理解，三剑客就是普通的命令，有的把他们叫做工具，在我看来都一样。而正则表达式就好比一个模版。三剑客能读懂这个模版。就这么简单。注意只有三剑客才能读懂这个模版哦！现在他们的关系和功能都搞懂了，接下来我们就来认识下他们怎么结合的。正则表达式是一个模版，这个模版是由一些普通字符和一些元字符组成。普通字符包括大小写的字母和数字，而元字符则具有特殊的含义。具体如下元字符功能意思 ^ 匹配行首表示以某个字符开头 $ 匹配行尾表示以某个字符结尾 ^$ 空行的意思表示空行的意思 . 匹配任意单个字符表示任意一个字符 * 字符* 匹配0或多个此字符表示重复的任意多个字符 \ 屏蔽一个元字符的特殊含义表示去掉有意义的元字符的含义 [] 匹配中括号内的字符表示过滤括号内的字符 .* 代表任意多个字符就是代表任意多个字符 lele\{n\} 用来匹配前面lele出现次数。n为次数就是统计前面lele出现的次数 lele\{n,\} 含义同上，但次数最少为n 从功能就可以看出 lele\{n,m\} 义同上，但lele出现次数在n与m之间从功能也可以看出 lele\{n,m\} 义同上，但lele出现次数在n与m之间从功能也可以看出三剑客的功能非常强大，但我们只需要掌握他们分别擅长的领域即可：grep擅长查找功能，sed擅长取行和替换。awk擅长取列。 …

为Onlyoffice添加LetsEncrypt证书

原文：https://stackoverflow.com/questions/50766990/how-to-properly-set-up-https-for-onlyoffice 按照官网建议，生成的证书保存情况如下： /app/onlyoffice/DocumentServer/data/certs# ls dhparam.pem onlyoffice.crt onlyoffice.csr onlyoffice.key 使用LetsEncrypt证书问题： Also, when copying the created certificates from /etc/letsencrypt/live/[domain] to /app/onlyoffice/DocumentServer/data/certs/, which file between cert.pem, chain.pem, and fullchain.pem becomes onlyoffice.crt? 回答： 1) cert.pem is onlyoffice’s onlyoffice.crt – This is your SSL certificate. 2) privkey.pem is onlyoffice.key – This is your Private Key. 3) You can usually ignore the …

Not only that, but you cannot change the mapped ports (forwarded ports) even when the container is stopped, so think twice when you run or start …
