Question

我使用sshpass使scp传输非交互式。它从文件夹中收集所有文件，并尝试将它们同步到SFTP服务器。我需要检查传输是否成功，所以我使用popen（）来发出命令。但是，如果失败，我确实会在运行我的应用程序的终端中看到错误消息，但我的代码无法捕获该输出..这是我的代码：

strcat(buf,"sshpass -p ");  //Use sshpass to make scp
strcat(buf,ftppass);        //non-interactive
strcat(buf," scp -o StrictHostKeyChecking=no -o ConnectTimeout=5 -P ");
strcat(buf,ftpport);
strcat(buf," ");
strcat(buf,locdlog);        //Location of logfiles
strcat(buf,arr[j]);     //Logname
strcat(buf," ");
strcat(buf,ftpname);
strcat(buf,"@");
strcat(buf,ftpadr);
strcat(buf,":");
strcat(buf,ftpdloc);        //Location of logfiles on FTP
strcat(buf,arr[j]);
fp = popen(buf, "r");       //Give actual sync command
if (fgets(buf,sizeof(buf)-1, fp) != NULL)//Check if sync succeeded
    printf("%s.\n",buf);    //If not, give error
else                //Else, move file to backup
{
    strcpy(buf,"mv -f ");
    strcat(buf,locdlog);
    strcat(buf,arr[j]);
    strcat(buf," ");
    strcat(buf,locdlog);
    strcat(buf,"backup/ ");
    system(buf);
}
pclose(fp);

我首先构建一个字符串来提供正确的sshpass / scp命令，然后用popen执行它。当我打印“buf”时，if语句似乎失败了。在失败之后，它仍然包含sshpass的命令，就像fgets不知何故什么也没做什么？
