I need some info about inode


Hi to all;

i red inode shows following info but i could n't list all informations in my system.
  • Size of file
  • Device ID
  • User ID of the file
  • Group ID of the file
  • The file mode information and access privileges for owner, group and others
  • File protection flags
  • The timestamps for file creation, modification etc
  • link counter to determine the number of hard links
  • Pointers to the blocks storing file’s contents

but i checked here

[oracle@localhost ~]$ pwd
/home/oracle

PHP Code:
oracle@localhost ~]$ ls -i
2583926 
='01-01-2012'"  2583845 Desktop    2583996 script.sql
2583925 =01-01-2012'"   
2584008 filey.txt  2583936 scripts.sql 
2583922 
'01-01-2012'"   2583928 first.lst  2731222 sss
3123298 afiedt.buf      2583930 latest.lst 2731129 test

2583933 bcx.lst         2731178 sample     2584009 text.txt
3123290 commit          2583927 samp.lst   2731209 touchdir1
2583989 cpu.sql         2731221 scriptsamp 2583991 tsmp.sql
2583990 dbtime.sql      2584012 scriptsamp.txt  3123292 update

@ hi chrism

Thnks for reply . Ya i am woking on stat command .

as per your reply , can we use stat instead of inode?

here also one doubt

Quote:
[oracle@localhost ~]$ stat script.sql
[oracle@localhost ~]$ stat -f script.sql
both showing different output. I am from oracle platform
I don't want too much confusions. what's your advice to check here ?

stat -f <file_name>
stat <file_name> or
except , is there any good command to know about file or directory ?

Thanks
Thiyagusham.G

I suggest you take a look at "man stat" (in general man pages are your friend).

The -f flag shows file-system wide information (e.g. the total number of free inodes) while stat with no arguments shows information for the file itself.

I don't know what you mean by "can we use stat instead of inode." The stat command gets the information it presents from the inodes stored on disks. In general, it is a very bad idea to manipulate the inodes directly, although it can be done with debugfs. Instead, they are manipulated by the file system driver in the kernel. Instead, we use programs like stat, mkdir, touch, etc. to manipulate file data and metadata.
