Linux command to check new files in file system - linux

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
Regards
Gabriel

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.

Shell script to find recently modified files [duplicate]

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 do you delete files older than specific date in Linux?

I used the below command to delete files older than a year.
find /path/* -mtime +365 -exec rm -rf {} \;
But now I want to delete all files whose modified time is older than 01 Jan 2014. How do I do this in Linux?
This works for me:
find /path ! -newermt "YYYY-MM-DD HH:MM:SS" | xargs rm -rf
You can touch your timestamp as a file and use that as a reference point:
e.g. for 01-Jan-2014:
touch -t 201401010000 /tmp/2014-Jan-01-0000
find /path -type f ! -newer /tmp/2014-Jan-01-0000 | xargs rm -rf
this works because find has a -newer switch that we're using.
From man find:
-newer file
File was modified more recently than file. If file is a symbolic
link and the -H option or the -L option is in effect, the modification time of the
file it points to is always used.
This other answer pollutes the file system and find itself offers a "delete" option. So, we don't have to pipe the results to xargs and then issue an rm.
This answer is more efficient:
find /path -type f -not -newermt "YYYY-MM-DD HH:MI:SS" -delete
find ~ -type f ! -atime 4|xargs ls -lrt
This will list files accessed older than 4 days, searching from home directory.

find files which have been modified in the last 30 minutes in Linux

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 {} \;

How to grep a group of files within a specific time range

I'm trying to write a script used on a buffer box that does full packet capture of network traffic. As it's for a fairly big network we split the captures into 100MB segments. At times of high network traffic oftentimes over a one minute period we will have multiple pcaps which cover that period.
So what I want to do is have a bash script that lets the analyst who is searching for something specify a date and time and how many minutes either side of it they want to search for files. Obviously I can do something like this -
ls -al | grep "Dec 1" | grep 02:00
ls -al | grep "Dec 1" | grep 02:01
and so on, get each result and grep each file individually for the specific keyword I'm looking for, but I'd like to be able to do a wider search for all files created within a time range and then grep each of them for the keyword.
I'm not entirely sure how to do that, any help would be appreciated.
find . -maxdepth 1 -newermt "2013-10-28 00:00:00" ! -newermt "2013-10-29 00:00:00"
What I want is for an analyst to say 1st December at 11:00am with a
keyword of "foo" searching 5 minutes either side. The script should
find all files created between 10:55am and 11:05am and grep them for
the keyword "foo"
This script uses touch -d to create temporary files with time stamps of the start and end of the time range, because older versions of find have the option -newer only, not -newermt, and touch -d conveniently allows using the given time specification (with little modification) with the minutes adjustment. The necessary modifications to the given date are done with sed and consist of moving the day after the month and removing suffixes as st or nd as well as the word at.
read -p'date and time: ' dat
read -p'+/- minutes: ' min
read -p'keyword: ' key
dat=`sed 's/\([0-9]\+\)\(st\|nd\|rd\|th\|\) \([^ ]*\)/\3 \1/; s/at //' <<<$dat`
touch -d"$dat $min min" /tmp/to
touch -d"$dat -$min min" /tmp/from
find . -type f -newer /tmp/from ! -newer /tmp/to | xargs grep "$key"
rm /tmp/from /tmp/to
Check out find with the -cmin or -ctime arguments.
So,
find -iname "*.log" -mtime +30 -mtime -90 -exec grep plasma {} \;
, would find files ending in ".log" which were modified greater than 30 days ago, but less than 90 days, then run said file through grep looking for the word "plasma".
Say you want 20131130 from 0100 to 0130 -
This does that with find:
touch -t 201311300100 dummy1
touch -t 201311300130 dummy2
find /path/to/logs type -f \( -newer dummy1 -a ! -newer dummy2 \) -name '*.log'
the 201311300100 bit is a touch timestring. I posted the most vanilla version I know because of the UNIX tag....

How do I find all the files that were created today in Unix/Linux?

How do I find all the files that were create only today and not in 24 hour period in unix/linux
On my Fedora 10 system, with findutils-4.4.0-1.fc10.i386:
find <path> -daystart -ctime 0 -print
The -daystart flag tells it to calculate from the start of today instead of from 24 hours ago.
Note however that this will actually list files created or modified in the last day. find has no options that look at the true creation date of the file.
find . -mtime -1 -type f -print
To find all files that are modified today only (since start of day only, i.e. 12 am), in current directory and its sub-directories:
touch -t `date +%m%d0000` /tmp/$$
find . -type f -newer /tmp/$$
rm /tmp/$$
Source
I use this with some frequency:
$ ls -altrh --time-style=+%D | grep $(date +%D)
After going through many posts I found the best one that really works
find $file_path -type f -name "*.txt" -mtime -1 -printf "%f\n"
This prints only the file name like
abc.txt not the /path/tofolder/abc.txt
Also also play around or customize with -mtime -1
This worked for me. Lists the files created on May 30 in the current directory.
ls -lt | grep 'May 30'
Use ls or find to have all the files that were created today.
Using ls : ls -ltr | grep "$(date '+%b %e')"
Using find : cd $YOUR_DIRECTORY; find . -ls 2>/dev/null| grep "$(date '+%b %e')"
find ./ -maxdepth 1 -type f -execdir basename '{}' ';' | grep `date +'%Y%m%d'`
You can use find and ls to accomplish with this:
find . -type f -exec ls -l {} \; | egrep "Aug 26";
It will find all files in this directory, display useful informations (-l) and filter the lines with some date you want... It may be a little bit slow, but still useful in some cases.
Just keep in mind there are 2 spaces between Aug and 26. Other wise your find command will not work.
find . -type f -exec ls -l {} \; | egrep "Aug 26";
If you're did something like accidentally rsync'd to the wrong directory, the above suggestions work to find new files, but for me, the easiest was connecting with an SFTP client like Transmit then ordering by date and deleting.
To get file before 24 hours execute below command:
find . -type f -mtime 1 -exec ls -l {} \;
To get files created today execute below command:
find . -type f -mtime -1 -exec ls -l {} \;
To Get files created before n days before, where +2 is before 2 days files in below command:
find . -type f -mtime +2 -exec ls -l {} \;
