Hello,

First of all I wish to thank you all for your answers.

In did I miss understood the minus and the plus thingys on the man page.
The find -type f -mtime +7 did worked for me.

be careful, esp. if you do not use -type f . You can bracket 'between 7
and 9 days' etc with:

   find -type f -mtime +7 -a -mtime -9

This is useful for answering questions like 'wtf happened to my
not-backed-up file xxx.c 3 days ago, pretty please $DEITY make there
be a backup somewhere'.

2.3.2 Comparing Timestamps
--

As an alternative to comparing timestamps to the current time, you can
compare them to another file's timestamp.  That file's timestamp could
be updated by another program when some event occurs.  Or you could set
it to a particular fixed date using the `touch' command.  For example,
to list files in `/usr' modified after February 1 of the current year:

 touch -t 0201 /tmp/stamp$$
 find /usr -newer /tmp/stamp$$
 rm -f /tmp/stamp$$

 -- Test: -anewer file
 -- Test: -cnewer file
 -- Test: -newer file
 True if the file was last accessed (or its status changed, or it
 was modified) more recently than FILE was modified.  [...]
 As an example, to list any files modified since
 `/bin/sh' was last modified:

  find . -newer /bin/sh

I guess this is what you're looking for?

You used the wrong format. Instead of -7 you should use +7.

  -n for less than n,
   n  for exactly n.

You need the "greater than n" (greater = older).

I'm not sure what you want. If you specify -mtime 7, it will give you
files changed within 24 hours starting 7 days ago and ending 8 days
ago.

If you specify -7 it will give you files that were modified from NOW
up to seven days ago (ending time 7 days).

If you specify +7, it will give you files modified up to and including
7 days ago, but nothing modified since then.


HTH,

Geoff.

find -mtime and wrong data return

[ik]

Hello,

I wish to use the find command in order to find all the files that
were created prior to specific file.

So I tried to use the following command:

find -type f -mtime -7

In order to get all the files that where modified prior to  a week
ago, but it only gives me files that where last changed a week ago,
and not prior to that at all.

I can't find any other way to get such data without using some "bash magic".

Am I missing something here, or can't I get files prior to what I
specy on -mtime ?

Thanks,

Ido

Can you give a brief explanation as to why and by what factor? Didn't
manage to find any simple explanation on the web.


First mentioned in Advanced Programming in the UNIX(R) Envionment by Stevens, pipe operations seems to be faster or 
equell to any other IPC method (ignoring non synchronized shared memory, of course).


While it should be noted Stevens original recommendation pretains to stream (a.k.a bidirectional) pipes and AFAIK Linux 
does not actually support stream pipes, as well as basing his claims on measurements on Unix systems other then Linux, I 
never the less believe that the affarmation that pipes are as fast or faster then any other IPC method (bar non 
synchronized shared memory) is true.


Which shouldn't surprise anyone, as pipes are actually the first ever Unix IPC 
method, so it have a long time to evolve :-)

Cheers,
Gilad

In that case one should be able to take advantage of the faster pipes 
even for 1:n situations.


The fater nature of pipes beyond Unix domain sockets are very minimal, enough 
that it would not be worth the trouble.
