There
are many times where we need to find when a file was created, modified or accessed.
This can be achieved in linux using ‘stat’ command.
So When we run stat command like ,
[xprk477@omhq13aa
~]$ stat prod
File: `prod'
Size: 25096 Blocks: 56 IO Block: 4096 regular file
Device:
fd1eh/64798d Inode: 131774 Links: 1
Access:
(0644/-rw-r--r--) Uid: ( 7488/
xprk477) Gid: ( 1007/ dev)
Access:
2012-08-19 21:41:19.000000000 -0500
Modify:
2012-07-22 22:52:02.000000000 -0500
Change:
2012-07-22 22:52:02.000000000 -0500
The
last 3 entries says about the access, modify and change timings of the file. lets
see what these say to us
Access
(atime): Access Time, or the last access
time of the file. Whenever we accessed, opened or touched the atime is updated
to the current time.
Change
(ctime): Change time, or last changed time of a file. Whenever we do operations
such as changing the ownership or permissions or even the content of the file, the
ctime is updated to current time.
Modify
(mtime): Modification time, update or modify the content of the file. Modify
the ownership or permissions does not change the Time stamp in this case.
Happy
leaning , More to Come J
