Linux Experiment report Two--file operation (cont.)

#include <stddef.h>

#include <stdio.h>

#include <sys/types.h>

The file where the #include <sys/stat.h>//stat function is located

#include <dirent.h>

int main (void)

{

DIR *DP;

struct Dirent *ep;

struct STAT st;

Char dirp[50];

printf ("Please input a dir name:/n");

scanf ("%s", &DIRP); Read Directory Name

Dp=opendir ("Dirp"); Open the given directory

printf ("filename:/ttype:/tpermission/taccesstime/tlastmodtime/tsize/t");

if (dp!=null)//If the directory opened successfully, then the operation is performed.

{

while (ep = Readdir (DP))//Read the cycle of each directory entry

{

if (ep->d_name[0]!= '. ') To determine if the first character of the file name is '. ', if it is, to indicate that it is an implied file, we do not move, otherwise operation

{

Use the STAT function to open the file information, the first parameter is the path of the file, the second parameter holds the information of the file

if (stat (ep->d_name,&st)!=-1)/Read success

{

printf ("%s/t", ep->d_name);

if ((ST.ST_MODE&S_IFMT) ==s_ifdir)//Determine the type of file

printf ("directory/t"); Directory

else if ((ST.ST_MODE&S_IFMT) ==s_ifblk)//block file

printf ("Block special file/t");

else if ((ST.ST_MODE&S_IFMT) ==S_IFCHR)//special character file

printf ("character Special file/t");

else if ((ST.ST_MODE&S_IFMT) ==s_ifreg)//Normal file

printf ("Ordinary file/t");

else if ((ST.ST_MODE&S_IFMT) ==S_IFIFO)//pipe file

printf ("Pipefile file/t");

printf ("%o/t", st.st_mode&0x1ff); Permissions for files

printf ("%15s/t", CTime (St.st_atime)); File creation time

printf ("%15s/t", CTime (St.st_mtime)); File Last Modified Time

printf ("%ld/n", st.st_size); Size of File

}

}

}

Closedir (DP)//Close Directory

}

Else

Puts ("couldn ' t open the directory./n"); Output cannot open path when open is unsuccessful

return 0;
