How do I find Files older than 4 hours in HP UX11.11

Nagu SR — Mon, 18 Aug 2008 09:14:48 GMT

Hi,

I need the following requirement.

In a directory /tmp/test I need to find any files which are not accessed from the last 4 hours. I dont want to delete any files but need to know the Path of that file.

As per me, in HP find command there is no -mmin option like in LINUX. So - mtime/-atime/-ctime will tell me the days old. But not by time (Here 6 hours.

Could someone help me please???

Use touch to create a reference file with the desired timestamp, then use find's -newer option - or ! -newer.

Hi,

Could you elaborate please....

In /tmp/test I need to find the files which are 4 hours old and need to know the path of the file. I dont want to change the time stamp of the file or I dont want to delete it also.

I just need those File names.(Path)

you can use perl for find your requirement

#perl -MFile::Find -le 'find(sub{print $File::Find::name if -f $_ && -M _ <= 4/24},@ARGV)' /path

Hi:

Since you are asking for the last *access* timestamp, the correct Perl solution is this:

# perl -MFile::Find -le 'find(sub{print $File::Find::name if -f $_ && -A _ >= 4/24},@ARGV)' /path

You can pass multiple '/path' arguments to the script, The age criteria is based on one day, so 4/24 of one day represents the desired 4-hours. The files returned by the above represent those whose access time equals or *exceeds* 4-hours. That is, they have *not* been recently accessed.

Thus Ahsan's copy-and-paste is incorrect.

If you really like the "find" in GNU/Linux,
you could try (building and) using that
"find" on HP-UX. The source code is
available:

http://www.gnu.org/software/findutils/

By the way, "-mmin" is for the _modified_
date-time. "-amin" is for the _accessed_
date-time. You want which one?

Nagu,

something like this could be useful

# touch -amt 200808181000 /tmp/ref1
# touch -amt 200808181400 /tmp/ref2

# find /opt/mtmc/ibs/import/reject -xdev -type f -newer /tmp/ref1 -a ! -newer /tmp/ref2 -exec rm {} \+

This will remove files that are newer (more recently modified) than 10:00AM AND NOT newer than 2:00 PM. Make sense? You can change the comand as needed to put the output into a file or directory or remove (as above).
