1.最近总结了 shell 中 function 的传递变量的几种方式 1.传递单个变量 2.传递数组变量 #!/bin/bash #trying to pass an variable. function func() { echo "The number of parameters is: ${#}" for line in "$@" do echo "$line" done } function func2() { pa
某日,同事问到关于new Date() 函数传参数,在火狐浏览器和谷歌浏览器控制台运行,会得到不同的结果,刚开始觉得不可能,后来实际操作才发现此陷阱 var date = new Date('2014-07-25T23:00:00'); alert(date); 在火狐浏览器返回的是: Date {Fri Jul 25 2014 23:00:00 GMT+0800} 火狐浏览器版本(通过navigator.userAgent输出):"Mozilla/5.0 (Windows NT 6.1; WO
argc是命令行总的参数个数 argv[]是argc个参数,其中第0个参数是程序的全名,以后的参数 命令行后面跟的用户输入的参数,比如: int main(int argc, char* argv[]) { int i; for (i = 0; i<argc; i++) cout<<argv[i]<<endl; cin>>i; retu
前不久入职实习生,现在在帮着组里面dalao们跑Case,时不时要上去收一下有木有Dump,每次敲命令太烦人于是逼着自己学写Shell脚本.一开始真的是很痛苦啊,也没能搞到书,只能凭网上半真半假的消息照葫芦画瓢!废话少说,上正文! =========================我是分割线========================= clear echo "Check_dump is a tool help you check dumps" numberOfSPs= comma
写python的时候报错: Exception : Traceback (most recent call last): File , in __bootstrap_inner self.run() File , in run RunYun( a, b, c, d, e, f ) File , in RunYun DbProxy.instance.insert(a, b) TypeError: insert() takes exactly arguments ( given) 明明定义的就是2个

n cross-platform, lowest-common-denominator sh you use: #!/bin/sh value=`cat config.txt` echo "$value" In bash or zsh, to read a whole file into a variable without invoking cat: #!/bin/bash value=$(<config.txt) echo "$value"
这样使用,后面的4000无效 setTimeout(removeGift(customer_id,gift_id),4000); function removeGift(customer_id,gift_id) { var x = 100; var y = 900; var rand = parseInt(Math.random() * (x - y + 1) + y); // 随机的位置 $("#gift_"+customer_id+"_"+gift_id).an
