It’s two steps but I like to do it this way:

First create a file with a particular date/time. In this case, the file is 2008-10-01 at midnight

touch -t 0810010000/tmp/t

Now we can find all files that are newer or older than the above file (going by file modified date. You can also use -anewer for accessed and -cnewer file status changed).

find /-newer /tmp/t
find /-not -newer /tmp/t

You could also look at files between certain dates by creating two files with touch

touch -t 0810010000/tmp/t1
touch -t 0810011000/tmp/t2

This will find files between the two dates & times

find /-newer /tmp/t1 -and -not -newer /tmp/t2

Other Example

The syntax is as follows:

ls -l  | grep 'yyyy-mm-dd'
ls -l | grep --color=auto '2006-01-05'

Where,

• 2006 – Year
• 01 – Month
• 05 – Day

You can sort it as follows:

ls -lu | grep --color=auto '2006-01-05'

find Command Example

If you need a specific date range many days ago, than consider using the find command. In this example find files modified between Jan/1/2007 and Jan/1/2008, in /data/images directory:

touch --date "2007-01-01" /tmp/start
touch --date "2008-01-01" /tmp/end
find /data/images -type f -newer /tmp/start -not -newer /tmp/end

You can save list to a text file called output.txt as follows:

find /data/images -type f -newer /tmp/start -not -newer /tmp/end > output.txt

List ALL *.c File Accessed 30 Days Ago

Type the following command

find /home/you -iname "*.c" -atime -30 -type -f

See also:

• See -atime and -mtime FAQ for more information.

You need to use the find command. Each file has three time stamps, which record the last time that certain operations were performed on the file:

[a] access (read the file’s contents) – atime

[b] change the status (modify the file or its attributes) – ctime

[c] modify (change the file’s contents) – mtime

You can search for files whose time stamps are within a certain age range, or compare them to other time stamps.

You can use -mtime option. It returns list of file if the file was last accessed N*24 hours ago. For example to find file in last 2 months (60 days) you need to use -mtime +60 option.

• -mtime +60 means you are looking for a file modified 60 days ago.
• -mtime -60 means less than 60 days.
• -mtime 60 If you skip + or – it means exactly 60 days.

So to find text files that were last modified 60 days ago, use
$ find /home/you -iname "*.txt" -mtime -60 -print

Display content of file on screen that were last modified 60 days ago, use
$ find /home/you -iname "*.txt" -mtime -60 -exec cat {} \;

Count total number of files using wc command
$ find /home/you -iname "*.txt" -mtime -60 | wc -l

You can also use access time to find out pdf files. Following command will print the list of all pdf file that were accessed in last 60 days:
$ find /home/you -iname "*.pdf" -atime -60 -type -f

List all mp3s that were accessed exactly 10 days ago:
$ find /home/you -iname "*.mp3" -atime 10 -type -f

There is also an option called -daystart. It measure times from the beginning of today rather than from 24 hours ago. So, to list the all mp3s in your home directory that were accessed yesterday, type the command
$ find /home/you -iname "*.mp3" -daystart -type f -mtime 1

Where,

• -type f – Only search for files and not directories

-daystart option

The -daystart option is used to measure time from the beginning of the current day instead of 24 hours ago. Find out all perl (*.pl) file modified yesterday, enter:

find /nas/projects/mgmt/scripts/perl -mtime 1 -daystart -iname "*.pl"

You can also list perl files that were modified 8-10 days ago, enter:
To list all of the files in your home directory tree that were modified from two to four days ago, type:

find /nas/projects/mgmt/scripts/perl -mtime 8 -mtime -10 -daystart -iname "*.pl"

-newer option

To find files in the /nas/images directory tree that are newer than the file /tmp/foo file, enter:

find /etc -newer /tmp/foo

You can use the touch command to set date timestamp you would like to search for, and then use -newer option as follows

touch --date "2010-01-05" /tmp/foo
# Find files newer than 2010/Jan/05, in /data/images
find /data/images -newer /tmp/foo

Read the man page of find command for more information:
