creation date of a file

[jpcast_real]

Hello Gurus,

can anyone tell me how can I know the creation date of a file in hp-ux 11i . I have found options in the ll and find which can tell me the ctime of a file . But , where can I get the creation time of the file.

Thanks a lot..

me thinks ctime should be the creation time, mtime is the modification (change...) time.

This is what the man of the find command says:



-atime n True if the file access time subtracted from
the initialized time is n-1 to n multiples of
24 h. The initialization time shall be a time
between the invocation of the find utility
and the first access by that invocation of
the find utility to any file specified by its
path operands. The access time of
directories in pathname_list is changed by
find itself.

-mtime n True if the file modification time subtracted
from the initialization time is n-1 to n
multiples of 24 h. The initialization time
shall be a time between the invocation of the
find utility and the first access by that
invocation of the find utility to any file
specified in its path operands.

-ctime n True if the time of last change of file
status information subtracted from the
initialization time is n-1 to n multiples of
24 h. The initialization time shall be a time
between the invocation of the find utility
and the first access by that invocation of
the find utility to any file specified by its

HI

I don't think you can.
you can find last access or last modification

man fstat

How do I find the creation time of a file?

You can't - it isn't stored anywhere. Files have a last-modified
time (shown by "ls -l"), a last-accessed time (shown by "ls -lu")
and an inode change time (shown by "ls -lc"). The latter is often
referred to as the "creation time" - even in some man pages -
but that's wrong; it's also set by such operations as mv, ln,
chmod, chown and chgrp.

The man page for "stat(2)" discusses this

and as per your post

atime => access time
mtime => modification time
ctime => change of status time

Ok ,thanks .

I just want to know what files are modified when I make an update to an application .

I try to use the :

find . -ctime 1 .

Shouldn't it give me the files modified during the last day???

find . -ctime -1

the last 24 hours.

Well, it you want files MODIFIED that is the mtime value; ctime is the CHANGED time. In this case, modified (mtime) means the data itself was changed; ie, the contents of a file. Changed (ctime) means the metadata (owner, group, mode, etc.) related to the file were changed.
