How do I find file by date under UNIX and Linux?
Linux and UNIX like operating systems do not store file creation time. However, you can use file access and modification time and date to find out file by date.
ls Command Example
The syntax is as follows:
ls -l | grep 'yyyy-mm-dd' ls -l | grep --color=auto '2006-01-05'
- 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 -atime and -mtime FAQ for more information.
