linux shell pwd 显示当前路径
假若有test.cpp
g++ test.cpp -o test
./test
想在test中找到当前执行程序所在的路径
可以再test.cpp中使用readlink函数
具体见如下实例：
#include<iostream>
#include<unistd.h>
#include<dirent.h>
#include<string.h>
#include<string>
using namespace std;
int main()
{
char buff[1024];
memset(buff,0,sizeof(buff));
int n = readlink("/proc/self/exe",buff,1023);
if(n<0)
{
cout<<"Get Path failed"<<endl;
return -1;
}
string path = buff;
int nLen = path.rfind('/');
path.erase(nLen,path.length() - nLen);
cout<<"zui zhong lu jing :"<<path<<endl;
return 0;
}
谨记是/proc/self/exe 在此某人载过跟头
