scp file

To transfer a file using SCP in the C language, you can follow these steps:

1. Include the necessary header files:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <errno.h>

1. Establish an SCP connection using the system command:

char command[100];
sprintf(command, "scp %s %s@%s:%s", local_file_path, username, hostname, remote_file_path);
system(command);

1. Handle any errors that may occur during the SCP transfer:

if (errno != 0) {
    perror("SCP transfer failed");
    exit(EXIT_FAILURE);
} else {
    printf("File transferred successfully");
}

1. Replace the placeholders with the actual file paths, username, and hostname for the SCP transfer. For example:

char* local_file_path = "/path/to/local/file";
char* username = "remote_username";
char* hostname = "remote_hostname";
char* remote_file_path = "/path/to/remote/directory";

These steps provide a basic outline for performing an SCP file transfer in the C language.
