将/tmp/template.txt文件复制到$1中指定的任何目录的示例脚本。
copy_script.sh
if [ $# -eq 0 ]; then
echo No Argument
echo "Usage: $0 "
else
cp /tmp/template.txt $1
fi
在此之前
wolf@linux:~$ ls -lh
total 4.0K
drwxrwxr-x 2 wolf wolf 4.0K Dis 31 10:08 'another directory'

这是Linux/GUN下的C程序:
#include<stdio.h>
#include<sys/time.h>
#define Max 1024*1024
int main()
{
struct timeval start,end;
long int dis;
int i;
int m=0;
int a[Max];
gettimeofday(&start,NULL);
for(i=0;i<Max;i += 1){
a[Max] *= 3;
}
我有两个函数返回生成器:
def f1():
return (i for i in range(1000))
def f2():
return ((yield i) for i in range(1000))
显然,从f2()返回的生成器比f1()慢两倍

用Nativescript编写应用程序。以下设置工作正常,没有错误:
// initialize cluster manager
dis.cluster_manager = new dis.clustering.ClusterManager(app.android.context, dis.gMap);
// Instantiate the cluster manager algorithm as is done in the ClusterManager, so we can access cluster items themselves, rather than cluster marke
我正在更改/分配数组(torch.cuda.floatTensor)上的值。我试过一些方法,但行不通。请帮帮我!
#1
#dis is [torch.cuda.FloatTensor of size 3185x1 (GPU 0)]
s = dis.size(0) #3185
for i in range (0,s,1):
if (dis[i,0] < 0):
dis[i,0]== 0
#There is no error but It does not work.
#2
#dis is [torch.cuda.FloatTensor of size 3185x1
我正在处理一个表单,但是如果四个输入的长度为0,我想停止表单,但我得到的是表单在调用e.preventDefault()之前提交。在提交表单输入之前,我可以对它做些什么来检查表单输入。
$('#job_in').click(function()
//form1.submit(function(e) // testing the form input
{
form1_name=$("input[data='form1_name']");
我有三张桌子
1- Dis
Oid || Name
2- CS
Oid || Name || Dis
3- Crit
Oid || CS || Date
我有一个查询,它给出了与当前月份和年份匹配的Dis和CS的名称:
SELECT Dis.Oid as 'DisOid', Dis.Name as 'Dis', CS.OID as 'CsOid' ,CS.Name as 'CS'
FROM Crit, CS, Dis
WHERE Crit.CS=CS.OID AND Dis.OID=CS.Dis
