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 {} \;

I'm using "ls -alR" to input directories and files in those directories into another text file.
ls -alR > testalR.txt
text file is created like so:
./test-file_folders/test_folder_1:
total 400
drwx------ 5 "user" "group" "size" May 2 10:30 test_file_1
.... file info ... more file info ....test_file_2
...more files
./test-file_folders/test_folder_2:
total 400
drwx------ 5 "user" "group" "size" Oct 2 11:35 test_file_1
.... file info ... more file info ....test_file_2
...more files
I am trying to show files that have not been accessed since October 2 2018.
I've tried:
`sed -n '/Oct 2 00:00/,/Oct/ 2 23:59/p' /testalR.txt
..but it produces no results. Is there a better way to display this or even possible?
Sorry, should have added this to begin with. I know using find -atime variant would be the best option. But we are using a system and a process that is bogged down by the find command. I am trying to find alternatives so using "find" can be avoided and wouldn't have to access directories directly each time I wanted to run a search.
Parsing the output of ls is a slippery slope.
Use find:
find . -type f -atime +3 -print
find . -type f -atime +3 -exec ls -uld {} +
Using -print simply returns a list of the filenames. Using -exec ls -ld {} + causes ls to be run for every file returned, giving you the details you may want.
The argument. to atime (or mtime or ctime) is in 24-hour steps. The argument can be positive or negative (or zero). Using -atime +3 finds a files that have been accessed at least FOUR days ago.
Using -exec ... {} + causes the command in "..." to be executed for every object returned, bundling as many objects (files) as possible at a time. This is much more efficient than forking a process for every file returned, as with:
... -exec ls -uld {} \;
One way to limit your results to a specific date, is to create two reference points (files) like this:
touch -amt 201809302359 f1
touch -amt 201810012359 f2
find . -type f \( -anewer f1 -a ! -anewer f2 \) -exec ls -uld -exec {} +
try with find:
find /folder -atime +30
where +30 = days
others params: man find
I created a script to check XML file available in the
folder for more than four hours. If the XML is not processed for more than four hours then I need to send a mail
for that I used the below find command but the mmin+240 is not working. Is there is any option to used instead of mmin. Please help on this.
find $OFILEPO/*.xml -mmin+240 -exec ls -ltr {} + | wc -l
when I execute the above find command with mmin got the below error.
**find: bad option -mmin
0
$ uname -a
HP-UX**
I think mmin is AIX command. Please suggest for HP_UX
Thanks in Advance
According to the man page hpux 10.20 - find (1), your implementation of find doesn't support the -mmin option.
The closest equivalent would be -mtime
-mtime n True if the file has been modified in n days.
Similar questions (Find files modified within one hour in HP-UX, how to find files modified in the last hour?) suggest creating a "reference" file with touch -mt $time and using find -newer.
Quoting the second link, you could do:
Create a temp file using the 'touch' command, such that the modification time is one hour in the past. For example:
# date +%m%d%H%m 06261006
# touch -mt 06260906 /tmp/tdate
# ll /tmp/tdate
-rw-r--r-- 1 root root 0 Jun 26 09:06 /tmp/tdate
Then run 'find' with the '-newer' switch, taking advantage of this
file:
find /mnt -newer /tmp/tdate -type f -xdev -exec ll {} \;
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 {} \;
👍
My goal is to find all text files with extension .log, which have the last access more than 24 hours ago and contain the required text.
Here is what I have already tried:
find / *.log -mtime +1 -print | grep "next" *.log
but this doesn't work.
Question is: how can I reach the goal I have described above?Maybe some ways to modify my find expression?
The problem with your command is that you are running the grep on the output of the find command - which means you are running it on the file names, not content (actually, since you have the *.log at the end, you run it on all *.log files, completely ignoring what your find command found). also, you need -name in order to filter only the .log files.
you can use the -exec flag of find to execute a command on each of the files that matches your find criteria:
find / -name "*.log" -mtime +1 -exec grep 'next' \{};
Try with xargs:
find / -name "*.log" -mtime +1 | xargs grep "next"
But also, note what the find manual says about the arg to -atime which also applies to -mtime. That is, your mtime as specified probably doesn't get the time period you want.
When find figures out how many 24-hour periods ago the file was last
accessed, any fractional part is ignored, so to match -atime +1, a
file has to have been accessed at least two days ago.
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.
