bin_founded.c

一个实现基本功能的shell命令解释器

#include "myfun.h"

int bin_founded(char *path_bin, char *path_argv[], const char *argv_bin)
{
	int i = 0;
	char temp[MAX/8] = "\0";
	while(path_argv[i] != NULL)
	{
		strcpy(temp, path_argv[i]);
		strcat(temp, "/");
		strcat(temp, argv_bin);
		if(access(temp, F_OK) == 0)
		{
			strcpy(path_bin, temp);
			return 0;
		}
		else
		{
			i++;
		}
	}
	return -1;
