I am using shell in an AS400. I need to find all files older than 120 minutes:
find . -type f -mmin 120
It fails with an error -mmin is not valid. Then I tried -mtime but since it is days, I can't use a decimal to find files which older than 120 minutes.
I've been unable to think of how to use the -newer option to get this done.
The -mmin option (and all other time option) have three options. They can be a number (e.g. 120) for exactly 120 minutes ago. They can also be +120 for more than 120 minutes and -120 for less than 120 minutes.
find . -mmin +120 -print
Note this command also will return . if it meets the time criteria. The current directory (.) is likely not what you need. You have options.
find . -type f -mmin +120 -print for only regular files.
find . -name \*.jpg -mmin +120 -print for only files ending in .jpg.
One more thing, it is considered unsafe to use the output of find to run other commands. You will need to use -print0 to null terminate the files then use xargs -0 to run the commands safely with special characters.

I'm trying to run an auto-delete script to free up space on a remote server.
The command I'm thinking to use is:
find . -atime +30 -mtime +30 -type f -delete
What I want is to also capture which files were successfully deleted and which failed because of access issue. How should I do this? I think this command below might take care of the failures only, but I'm not sure.
find . -atime +30 -mtime +30 -type f -delete 2>failed_deletions.txt
find out of the box does not print the files it processes. If you want to list the files, add a -print or -ls before the -delete.
This obviously prints all the files it processes, including the ones it fails to delete for whatever reason.
Redirecting standard output to a different file should be trivial to discover; command >stdout 2>stderr
The final command would become
find . -atime +30 -mtime +30 -type f \
-print -delete >success.txt 2>errors.txt
Less performant, but should do what you wanted:
find . -atime +30 -mtime +30 -type f -exec rm -v {} \; >successful.txt 2>failed.txt
I'm struggling with compressing my logs. I have a simple script which runs everynight
find /directory/logs -type f -mmin +1440 -print -exec gzip {} \;
But sometimes it skips my logs with different ending than *.log. For example it don't compress logs with *.log.1 *.log.0.lck etc.
Any ideas?
I suppose that you just don't use correctly the find command.
-mmin +1440 - find all files except last 1440min (24 hours)
-mmin -1440 or -mmin 1440 - find all files created in last 1440min (24 hours)
You can use "-mtime n", from man:
File's data was last modified n*24 hours ago. See the comments for -atime to understand how rounding affects the interpretation of file modification times.
So for you:
find /directory/logs -type f -mtime 1 -print -exec gzip {} \;
E.g., a MySQL server is running on my Ubuntu machine. Some data has been changed during the last 24 hours.
What (Linux) scripts can find the files that have been changed during the last 24 hours?
Please list the file names, file sizes, and modified time.
To find all files modified in the last 24 hours (last full day) in a particular specific directory and its sub-directories:
find /directory_path -mtime -1 -ls
Should be to your liking
The - before 1 is important - it means anything changed one day or less ago.
A + before 1 would instead mean anything changed at least one day ago, while having nothing before the 1 would have meant it was changed exacted one day ago, no more, no less.
Another, more humanist way, is to use -newermt option which understands human-readable time units.
Unlike -mtime option which requires the user to read find documentation to figure our what time units -mtime expects and then having the user to convert its time units into those, which is error-prone and plain user-unfriendly. -mtime was barely acceptable in 1980s, but in the 21st century -mtime has the convenience and safety of stone age tools.
Example uses of -newermt option with the same duration expressed in different human-friendly units:
find /<directory> -newermt "-24 hours" -ls
find /<directory> -newermt "1 day ago" -ls
find /<directory> -newermt "yesterday" -ls
You can do that with
find . -mtime 0
From man find:
[The] time since each file was last modified is divided by 24 hours and any remainder is discarded. That means that to
match -mtime 0, a file will have to have a modification in the past which is less than 24 hours ago.
On GNU-compatible systems (i.e. Linux):
find . -mtime 0 -printf '%T+\t%s\t%p\n' 2>/dev/null | sort -r | more
This will list files and directories that have been modified in the last 24 hours (-mtime 0). It will list them with the last modified time in a format that is both sortable and human-readable (%T+), followed by the file size (%s), followed by the full filename (%p), each separated by tabs (\t).
2>/dev/null throws away any stderr output, so that error messages don't muddy the waters; sort -r sorts the results by most recently modified first; and | more lists one page of results at a time.
For others who land here in the future (including myself), add a -name option to find specific file types, for instance: find /var -name "*.php" -mtime -1 -ls
This command worked for me
find . -mtime -1 -print
Find the files...
You can set type f = file
find /directory_path -type f -mtime -1 -exec ls -lh {} \;

how to find files based upon time information, such as creation, modified and accessed. It is useful to find files before a certain time, after a certain time and between two times. what command in Linux would i have to use ?
I understand to find setuid files on linux computers i would have to use :
find / -xdev ( -perm -4000 ) -type f -print0 | xargs -0 ls -l
How do i check for files which have been modified in the last 30 minutes. (I created a new file called FILE2)
Just add -mtime -30m. I might be wrong about the actual syntax, but you get the idea. See man find.
Answer on your question is
find . -cmin -30 -exec ls -l {} \;
We have linux machine we would like to check what new files have been added between a certain date range.
I only have SSH access to this box and it's openSUSE 11.1
Is there some sort of command that can give me a list of files that have been added to the filesystem between say 04/05/2011 and 05/05/2011
Thanks

There are bunch of ways for doing that.
First one:
start_date=201105040000
end_date=201105042359
touch -t ${start_date} start
touch -t ${end_date} end
find /you/path -type f -name '*you*pattern*' -newer start ! -newer end -exec ls -s {} \;
Second one:
find files modified between 20 and 21 days ago:
find -ctime +20 -ctime -21
finds files modified between 2500 and 2800 minutes ago:
find -cmin +2500 -cmin -2800
And read this topic too.
Well, you could use find to get a list of all the files that were last-modified in a certain time window, but that isn't quite what you want. I don't think you can tell just from a file's metadata when it came into existence.
Edit: To list the files along with their modification dates, you can pipe the output of find through xargs to run ls -l on all the files, which will show the modification time.
find /somepath -type f ... -print0 | xargs -0 -- ls -l
I misunderstood your question. Depending on what filesystem you are using, it may or may not store creation time.
My understanding is that ext2/3/4 do not store creation time, but modified, changed (status, which is slightly different), and access times are.
Fat32 on the other hand does contain creation timestamps IIRC.
If you are using an ext filesystem, you have two options it seems:
1.Settle for finding all of the files that were modified between two dates (which will include created files, but also files that were just edited). You could do this using find.
2.Create a script/cronjob that will document the contents of your filesystem at some interval, e.g.
find / > filesystem.$(date +%s).log
and then run diffs to see what has been added. This, of course, would prevent you from looking backwards to time before you started making these logs.
You can try one of these:
find -newerct "1 Aug 2013" ! -newerct "1 Sep 2013" -ls
find . -mtime $(date +%s -d"Jan 1, 2013 23:59:59") -mtime $(date +%s -d"Jan 2, 2016 23:59:59")
find /media/WD/backup/osool/olddata/ -newermt 20120101T1200 -not -newermt 20130101T1400
find . -mtime +1 -mtime -3
find . -mtime +1 -mtime -3 > files_from_yesterday.txt 2>&1
find . -mtime +1 -mtime -3 -ls > files_from_yesterday.txt 2>&1
touch -t 200506011200 first
touch -t 200507121200 last
find / -newer first ! -newer last
#!/bin/bash
for i in `find Your_Mail_Dir/ -newermt "2011-01-01" ! -newermt "2011-12-31"`; do
mv $i /moved_emails_dir/
Hope this helps.
