Edge浏览器自动给数字、IP地址加下划线
Posted on: 2021-07-31 09:35:11 in Business visited: 256Edge浏览器自动给数字、IP地址加下划线。
尤其是IP地址，不仔细看的话，以为是加了一个链接，实际不是，点击这个链接，会弹出一个对话框，让你选中打开方式。
这种情况下，一般是Edge认为是识别到了一个电话号码。
解决方法是在HTML文件中增加下面一行：
<meta name="format-detection" content="telephone=no">
类似的选项共有3个。
- meta name=”format-detection” content=”telephone=no”
- meta name=”format-detection” content=”email=no”
- meta name=”format-detection” content=”adress=no”
telephone
主要作用是是否设置自动将你的数字转化为拨号连接
telephone=no 禁止把数字转化为拨号链接
telephone=yes 开启把数字转化为拨号链接，默认开启
email
告诉设备不识别邮箱，点击之后不自动发送
email=no 禁止作为邮箱地址
email=yes 开启把文字默认为邮箱地址，默认情况开启
adress
adress=no 禁止跳转至地图
adress=yes 开启点击地址直接跳转至地图的功能, 默认开启
在java7中使能TLS1.2
Posted on: 2021-07-16 13:49:06 in Business visited: 220TSL1.2在Java8中默认是选中的，在Java7中默认是不选中。
不选中的情况下，某些软件无法使用，比如BMC的Java KVM功能。
修改方法是：
1：从菜单找到java control，或者找到java目录，执行jcontrol
2：在advanced标签下，选中enable tls1.1，以及enable tls1.2
Git Your branch is ahead of 'origin/master' by X commits费事不费心解决方法
Posted on: 2021-06-13 09:39:01 in Business visited: 309现象描述：有时候混合使用git gerrit，代码已经push，但还提示ahead，再次提示又担心出现问题。
#git pull
Already up-to-date
#git status ./
On branch master
Your branch is ahead of 'origin/master' by X commits
解决方法：
1：将代码复制到另外一个地方进行备份。
2：进行代码回退，修改会丢失，git reset --hard HEAD~x
3：然后再次查看git status,如果Your branch is behind of 'origin/master' by X commits，使用git pull再次更新
3：用备份代码与当前代码比较，重新commit，重新push。
注：x换成具体的数值。

openssl介绍
Posted on: 2021-06-06 21:20:26 in Business visited: 230openssl是一个安全套接字层密码库，囊括主要的密码算法、常用密钥、证书封装管理功能及实现ssl协议。OpenSSL整个软件包大概可以分成三个主要的功能部分：SSL协议库libssl、应用程序命令工具以及密码算法库libcrypto。
在linux系统下安装openssl，需要安装两个软件包：openssl和libssl-dev。具体使用方法和参数列表可参见命令行帮助。使用“openssl help”查看帮助信息

ipmitool lanplus编译需要openssl libssl-dev否则会报错undefined reference to RVP_CIPHER_CTX_reset
Posted on: 2021-06-05 17:18:45 in Business visited: 840本文描述如何在ubuntu下编译lanplus，并描述可能遇到的问题。
1：下载ipmitool的最新版本，并查看如何安装文件INSTALL
2：根据INSTALL文件最简单的，要使用./configure; make; make install进行编译安装
3：如果在执行configure，查看接口如果不支持lanplus，则可能是缺少库文件，需要安装openssl和libssl-dev
可以使用以下命令进行安装。
# apt-get install openssl
# apt-get install libssl-dev
异常表现一：lanplus：no

grep命令用法汇总
Posted on: 2021-05-27 08:53:17 in Business visited: 203
| cat example.txt | grep "abcdef" | 匹配字符串abcedf，匹配大小写 |
| cat example.txt | grep -i "abcdef" | 匹配字符串abcedf，忽略大小写 |
| grep --binary-files=without-match -i -r ">phyinfo" ./ | 查找时忽略二进制文件 |
$ grep --help
用法: grep [选项]... PATTERN [FILE]...
在每个 FILE 或是标准输入中查找 PATTERN。
默认的 PATTERN 是一个基本正则表达式(缩写为 BRE)。
例如: grep -i 'hello world' menu.h main.c
正则表达式选择与解释:
-E, --extended-regexp PATTERN 是一个可扩展的正则表达式(缩写为 ERE)
-F, --fixed-strings PATTERN 是一组由断行符分隔的字符串。
-G, --basic-regexp PATTERN 是一个基本正则表达式(缩写为 BRE)
-P, --perl-regexp PATTERN 是一个 Perl 正则表达式
-e, --regexp=PATTERN 用 PATTERN 来进行匹配操作
-f, --file=FILE 从 FILE 中取得 PATTERN
-i, --ignore-case 忽略大小写
-w, --word-regexp 强制 PATTERN 仅完全匹配字词
-x, --line-regexp 强制 PATTERN 仅完全匹配一行
-z, --null-data 一个 0 字节的数据行，但不是空行
杂项:
-s, --no-messages 不显示错误信息
-v, --invert-match 选中不匹配的行
-V, --version 显示版本信息并退出
--help 显示此帮助并退出
输出控制:
-m, --max-count=NUM NUM 次匹配后停止
-b, --byte-offset 输出的同时打印字节偏移
-n, --line-number 输出的同时打印行号
--line-buffered 每行输出清空
-H, --with-filename 为每一匹配项打印文件名
-h, --no-filename 输出时不显示文件名前缀
--label=LABEL 将LABEL 作为标准输入文件名前缀
-o, --only-matching 只显示匹配PATTERN 部分的行
-q, --quiet, --silent 不显示所有常规输出
--binary-files=TYPE 设定二进制文件的TYPE 类型；
TYPE 可以是`binary', `text', 或`without-match'
-a, --text 等同于 --binary-files=text
-I 等同于 --binary-files=without-match
-d, --directories=ACTION 读取目录的方式；
ACTION 可以是`read', `recurse',或`skip'
-D, --devices=ACTION 读取设备、先入先出队列、套接字的方式；
ACTION 可以是`read'或`skip'
-r, --recursive 等同于--directories=recurse
-R, --dereference-recursive 同上，但遍历所有符号链接
--include=FILE_PATTERN 只查找匹配FILE_PATTERN 的文件
--exclude=FILE_PATTERN 跳过匹配FILE_PATTERN 的文件和目录
--exclude-from=FILE 跳过所有除FILE 以外的文件
--exclude-dir=PATTERN 跳过所有匹配PATTERN 的目录。
-L, --files-without-match 只打印不匹配FILEs 的文件名
-l, --files-with-matches 只打印匹配FILES 的文件名
-c, --count 只打印每个FILE 中的匹配行数目
-T, --initial-tab 行首tabs 分隔（如有必要）
-Z, --null 在FILE 文件最后打印空字符
文件控制:
-B, --before-context=NUM 打印文本及其前面NUM 行
-A, --after-context=NUM 打印文本及其后面NUM 行
-C, --context=NUM 打印NUM 行输出文本
-NUM 等同于 --context=NUM
--color[=WHEN],
--colour[=WHEN] 使用标记高亮匹配字串；
WHEN 可以是`always', `never'或`auto'
-U, --binary 不要清除行尾的CR 字符(MSDOS/Windows)
-u, --unix-byte-offsets 忽略CR 字符，报告字节偏移
(MSDOS/Windows)
