Write A Program in Python / C++ To Read & Display The i-Node Information For A Given Text or Image file.

============  Python Program ============

import os,sys
print 'Enter file name'
name=raw_input()
fd=os.open(name,os.O_RDWR)
info=os.fstat(fd)

print "File Information is as follows:"
print "File inode number:",info.st_ino
print "Device number:",info.st_dev
print "Number of link:",info.st_nlink
print "UID of the file:%d" %info.st_uid
print "GID of the file:%d" %info.st_gid
print "Size:",info.st_size
print "Access time:",info.st_atime
print "Modify time:",info.st_mtime
print "Change time:",info.st_ctime
print "Protection:",info.st_mode
print "Number of blocks allocated:",info.st_blocks
print "Size of blocks:",info.st_blksize
 
os.close(fd)

============ OUTPUT ============

hnpandya@localhost ~]$ python inode.py

Enter file name
inode.py
File Information is as follows:
File inode number: 431632
Device number: 64769
Number of link: 1
UID of the file:1000
GID of the file:1000
Size: 604
Access time: 1413137831.37
Modify time: 1413068044.91
Change time: 1413137821.02
Protection: 33270
Number of blocks allocated: 8
Size of blocks: 4096
