How to find File-Directory creation date ?

$stat <file name> command basically displays file or file-system status. stat command is used to find Access , Modify, Change date and time for any file or directory in Unix like operating systems. e.g

$stat /root/install.log
File: `/root/install.log'
Size: 17154           Blocks: 48         IO Block: 4096   regular file
Device: fd00h/64768d    Inode: 1177346     Links: 1
Access: (0644/-rw-r--r--)  Uid: (    0/    root)   Gid: (    0/    root)
Access: 2011-09-30 16:24:39.000000000 +0100
Modify: 2011-09-30 16:28:59.000000000 +0100
Change: 2011-09-30 16:29:04.000000000 +0100

As show in above example, It also displays owner and group associated with particular file. permissions on particular file. etc
There is no creation date available as far as I know unless you log the file creation date in a script. You can use the stat command as mentioned above to get the time stamp for last access, last change and last modification time.

$stat --version

How to find directory last change / modification date and time?
How to find file / filesystem last change / modification date and time?
How to find last “access” date and time for file / directory?

As we are talking about time stamp (access, change, modify) for files / directories in linux, we much consider talking about “touch” command.
“touch” [options] <file name(s)>  :
Mainly touch command is used to change time stamp for files. If file does not exist then touch command creates file with current time stamp. e.g

$touch file1 file2 file3

will create 3 files in your present working directory with current time stamp.
Several of touch’s options are specifically designed to allow the user to change the timestamps for files. For example, the -a option changes only the access time, while the -m option changes only the modification time. The use of both of these options together changes both the access and modification times to the current time, for example:

$touch -am file11

The -r (i.e., reference) option followed directly by a space and then by a file name tells touch to use that file’s time stamps instead of current time. For example, the following would tell it to use the times of file4 for file5:

$touch -r myfile yourfile

The -B option modifies the timestamps by going back the specified number of seconds, and the -F option modifies the time by going forward the specified number of seconds. For example, the following command would make file7 30 seconds older than file6.

$touch -r myfile -B 30 yourfile

Importance of touch command.
Ah, beware before you use touch command on production system.
