history

在一次测试环境遇到的情况，发现服务莫名其妙挂了，以为服务有bug，查了一下午，后来一个同事说：“是我把服务关了啊”。。。。 是可忍孰不可忍，原生的history命令，只能看到输入的命令历史，看不到什么时候，谁输入的。 特此在网上找到修改history命令的办法： 1.用root用户打开系统环境变量设置的文件 vim /etc/profile 2.在最下面，插入下面几行代码 USER_IP=`who -u am i 2>/dev/null| awk '{print $NF}'|sed -e 's/[()]//g'` export HISTTIMEFORMAT="[%F %T][`whoami`][${USER_IP}] " export HISTSIZE=100000 #命令历史记录的条数 export HISTFILESIZE=100000 #命令历史文件记录历史的条数 export HISTIGNORE='ls*:ll' #忽略的命令 3.让环境变量生效 source /etc/profile 以后再输入history命令，就会变成下面的样子了，有时间，有用户，有ip，而且保存最近10万条记录。 哼哼，再也不怕背锅了 来源： https://www.cnblogs.com/dijia478/p/11782974.html

When I run history in Bash, I get a load of results (1000+). However, when I run history the zsh shell I only get 15 results. This makes grepping history in zsh mostly useless. My .zshrc file contains the following lines: HISTFILE=~/.zhistory HISTSIZE=SAVEHIST=10000 setopt sharehistory setopt extendedhistory How can I fix zsh to make my shell history more useful? UPDATE If in zsh I call history 1 I get all of my history, just as I do in Bash with history . I could alias the command to get the same result, but I wonder why does history behave differently in zsh and in Bash. The OP has already

I am trying to get a handle on using URL hashes in jQuery to control history in Ajax and make links / pages book-markable. I have tried almost every plug-in out there, and I cant seem to get any to work properly, so I dont have any code examples really. But I am open to any suggestions, information, tutorials, etc. The difference on one of the pages I am trying to incorporate this into is that I have a jQuery animation driven splash/loading page, which is also the same page that all of the content will be loaded into. ..and on this link, I want to by-pass all of the splash / loading animation

I'm building a chat system based on ejabberd using an iOS client (and XMPPFramework ). My current chat system supports only one-on-one conversations between users saving a chat history on a MySQL database. In order to recreate the same chat system, i'd need ejabberd to retrieve chat history from my database so the users don't lose previous conversations when switching to the new chat system. I'd like not to save the conversation client-side since the iOS app can be deleted and reinstalled (or the user could switch device). Is it possible to make ejabberd read chat history from my MySQL db?
