Need the list of files which created in specific time

VVS — Wed, 16 Apr 2008 07:49:08 GMT

Hi all
I need the list of files which created in specific time.
Foe example: I need list of files in perticular directory which are created in last 1 hour.

Thanks

You can't get that info. You can only get a list of files modified in the last hour.

To do this, you would have to use touch to create a reference file of exactly one hour ago, then use "find . -newer ref-file".

Hi:

With Perl, this is easy:

# perl -MFile::Find -le 'find(sub{print $File::Find::name if -f $_ && -M _ <= 1/24},@ARGV)' /path

THis will search the directory or directories passed as the script argument looking for FILES that were *modified* during the last hour (1/24 of a day).

By the way, there is no such thing as a creatino timestamp in Unix. The 'mtime' or last modification timestamp is equivalent to a creation moment when a file is first instantiated. Thereafter, any change in the file's contents updates the 'mtime' in its inode.

Hi (again):

Was there something more that you wanted in your solution?

Hi James,

I tried your command and it doesn't work for me. I tried both relative and absolute path.

Does this have to be run in a script or is it good to run at the prompt?

Cheers

Correction

It returns nothing on HPUX 11.11

on my 11.23 (recently patched) system
it does

# /usr/bin/perl -MFile::Find -le 'find(sub{print $File::Find::name if -f $_ && -M _ <:q= 1/24},@ARGV)' /tmp
syntax error at -e line 1, near "<:"
Can't find string terminator "=" anywhere before EOF at -e line 1.

Hi (again):

> Vasu: I have 11.11 version of HP-Ux. So will it run on the same?

Yes, Perl should have been part of your 11i installation and hence my script will run.

> Vasu: Is there any cmd shows the files modified in last one hour in perticular directory?

Yes, this is the original script I posted for you. Simply pass the name of the directory you want to examine as the argument to the script. In the example I showd, I used '/path' as a generic argument label. You could use '/home' or '/home/vasu' or anything that is a directory.

> O'Kevin: Copy-and-paste my post and provide the directory or directories you are interested in examining as arguments. The absence of any output means that there were no files meeting the criteria.

You have a very old Perl on your server. The 'File::Find' module wasn't part of the Perl Core distribution at that time.

I suggest that you download and install a current Perl. No reboot is necessary!

...and if per chance this is an old 10.20 system, Merijn has a Perl for that:

Perl 5.8.8 is an excellent version for production. Perl 5.10 was recently released too.

Touch a reference file (say /tmp/ref_file) with a specific timestamp that corresponds to approx 1 hr ago using:
touch -t CCYYMMDDhhmm.SS /tmp/ref_file

run a find:
find start_dir -type f -newer /tmp/ref_file

as per "man find":
-newer file True if the current file has been modified more recently than the argument file.

> Rangarajan :

Why resurrect a 10-day old thread that has a bunny and for which your alternate proposal was first suggested by someone else on the opening day?

While 'find -newer ...' certainly works, it doesn't provide the moving window of time yielded by the Perl snippet I showed. Of course, you could wrap a 'touch' and a 'find' in a small shell script that creates the reference point; performs the 'find' and then removes the (then) useless reference file.
