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
莫找借口失败，只找理由成功。(不为失败找理由，要为成功找方法)
