发帖数: 1436 | 1 文件中有一段需要换成新提供的内容，请问用shell/perl怎么操作？谢谢了。
举个例子，需要被替换的内容如下：
{
logic_name => 'mask',
batch_size => 10,
resource => 'rusage[myens_build1tok=11]',
memory => ['500k', '1k', '3k'],
retries => 0,
},
想要替换成的内容如下：
{
logic_name => 'mask',
batch_size => 100,
resource => 'rusage[myens_build1tok=10]',
memory => ['500MB', '1GB', '3GB'],
retries => 3,
retry_resource => 'rusage[myens_build1tok=10]', ... 阅读全帖 |

有没有可能awk和sed直接搞定？
export a=`awk '{if($0~/{/){x="";do{x=x"\n"$0}while(getline&&!/},/)};if (x~/
logic_name/&&x~/mask/){print x"\n"$0|"awk 'NF'"};x=$0}' file`
export b=`echo "{

batch_size => 100,

include
...
static double myclock()
{
struct rusage ru;
(void) getrusage(0,&ru);
return(ru.ru_utime.tv_sec + ru.ru_utime.tv_usec / 1.0e6);
}
现在程序移植到C++上，这个函数编译不过去。
大家在C++上用什么计时？clock()容易溢出，time(0)又不够精确。我的程序有些
部分运行时间很长。 |

发帖数: 39 | 6 Hi,
I am trying to track the memory usage, especially the page faults during
allocation. I found there is a getrusage() method, which tracks page faults
and page reclaims. My questions are as follows:
1. what does "page reclaims" mean? how to interpret it? Does that mean (a) if
a page Pi was used for Ni times without page faults, then ru_minflt = \sum {
Pi * Ni} ?
reference:
http://www.fifi.org/cgi-bin/man2html/usr/share/man/man2/getrusage.2.gz
struct rusage { ...
long ru_minfl |
