Hi
I've made some test with perl script to learn more about mtime...
So, my question is :
Why the mtime from find
are not the same as mtime from unix/linux in
or in stat() function in perl : stat - perldoc.perl.org
Quote:
9 mtime last modify time in seconds since the epoch
If I use the find command to find files older than n days I have to enter
find . -mtime +(n-1). I tried this on a Solaris 9 system and also Linux. Is this something that all Unix veterans know about (I'm new to Unix)? If so, maybe my man pages need to be updated (how to do this?). :confused: (4 Replies)
...what am i doing wrong??
I need to find all files older than 30 days and delete but I can't get it to pull details for ANY + times. The file below has a time stamp which is older than 1 day, however if I try and select it using any of the -time flags it just doesn't see it. (the same thing... (1 Reply)
I am using HP-UNIX , The below command doesnt display anything although i have changed a file in the directory by
toutch -t 200010101800 nfile
find /tmp/transfer/ -name "*.*" -mtime +1
Any problrm with the find command i written . .Please help ??..
Thanks,

Hello everyone,
I have got two queries:
1) I want to do some work on files that were last modified yesterday.
Will find ... -mtime -2 be correct or -mtime-1?
2)What about finding files that were modified today? Will it be -mtime -0 or -mtime -1?
Thanks. (1 Reply)
Hi guys, I am looking for a way of moving all files out of a directory with a time stamp greater then the one I specify. Can anyone suggest a way of doing so?
For example, move all files out of dir1 which were created after 17:00 into dir2.
Thanks :) (1 Reply)
Hi,
i try to catch all files in a dir ,without going down in subdir , which don't have file extension and older than 10 days for example:
my dir :
drwxr-xr-x 7 notes01 notes 4096 Mar 8 14:11 .
drwxr-xr-x 116 root system 4096 Mar 9 11:17 ..
-rw-r----- 1 notes01... (4 Replies)
What is "-mtime 0" option in find command. Does it consider the files that are of today lets say today is 4th Aug or will include files 24 hrs past from the current time???? (3 Replies)
Hi, so I was using mtime and its not behaving the way I would think its supposed too. I have two pdf files. One modified today and another 6 months ago. I upload them to the solaris server. Then I run the below find statements.
This finds my 2 files
find *.pdf -type f -name '*.pdf'
this finds... (2 Replies)
Hi,
I'm trying to find all files that have a .ksh and .p extension and that are 7 days old by using the below find command but it doesn't seem to as expected. It gives me random results.. Can someone point out what may be wrong?
find . -name "*.ksh" -o -name "*.p" -mtime -7 (2 Replies)

stat
STAT(5) File Formats Manual STAT(5)NAME
stat, wstat - inquire or change file attributes
SYNOPSIS
Tstat tag[2] fid[2]
Rstat tag[2] fid[2] stat[116]
Twstat tag[2] fid[2] stat[116]
Rwstat tag[2] fid[2]
DESCRIPTION
The stat transaction inquires about the file identified by fid. The reply will contain a 116-byte (DIRLEN in <libc.h>) machine-independent
directory entry laid out as follows:
name[28] file name; must be / if the file is the root directory of the server
uid[28] owner name
gid[28] group name
qid.path[4] the file server's identification for the file
qid.vers[4] version number for given path
mode[4] permissions and flags
atime[4] last access time
mtime[4] last modification time
length[8] length of file in bytes
type[2] for kernel use
dev[2] for kernel use
Integers in this encoding are in little-endian order (least significant byte first). The convM2D and convD2M routines (see fcall(2)) con-
vert between directory entries and C structs.
This encoding may be turned into a machine dependent Dir structure (see stat(2)) using routines defined in fcall(2).
The mode contains permission bits as described in intro(5) and the following: 0x80000000 (this file is a directory), 0x40000000 (append
only), 0x20000000 (exclusive use). Writes to append-only files always place their data at the end of the file; the offset in the read or
write message is ignored, as is the OTRUNC bit in an open. Exclusive use files may be open for I/O by only one fid at a time across all
clients of the server. If a second open is attempted, it draws an error. Servers may implement a timeout on the lock on an exclusive use
file: if the fid holding the file open has been unused for an extended period (of order at least minutes), it is reasonable to break the
lock and deny the initial fid further I/O.
The two time fields are measured in seconds since the epoch (Jan 1 00:00 1970 GMT). The mtime field reflects the time of the last change
of content. For a plain file, mtime is the time of the most recent create, open with truncation, or write; for a directory it is the time
of the most recent remove, create, or wstat of a file in the directory. Similarly, the atime field records the last read of the contents;
also it is set whenever mtime is set. In addition, for a directory, it is set by an attach, walk, or create, all whether successful or
not.
The length records the number of bytes in the file. Directories and most files representing devices have a conventional length of 0.
The stat request requires no special permissions.
The wstat request can change some of the file status information. The name can be changed by anyone with write permission in the parent
directory; it is an error to change the name to that of an existing file. The mode and mtime can be changed by the owner of the file or
the group leader of the file's current group. The directory bit cannot be changed by a wstat; the other defined permission and mode bits
can. The gid can be changed: by the owner if also a member of the new group; or by the group leader of the file's current group if also
leader of the new group (see intro(5) for more information about permissions and users(6) for users and groups). None of the other data
can be altered by a wstat. In particular, there is no way to change the owner of a file.
A read of a directory yields an integral number of directory entries in the machine independent encoding given above (see read(5)).
ENTRY POINTS
Stat messages are generated by fstat and stat.
Wstat messages are generated by fwstat and wstat.
