I have a directory containing lots of files. The output of ls
command is
-rw-r--r-- 1 nobody nogroup 427494 May 26 13:59 14_20150526065238928590_102.txt
-rw-r--r-- 1 nobody nogroup 2113592 May 26 14:00 14_20150526065238928590_105.txt
-rw-r--r-- 1 nobody nogroup 429947 May 26 14:00 14_20150526065238928590_110.txt
-rw-r--r-- 1 nobody nogroup 453831 May 27 14:00 14_20150526065238928590_112.txt
-rw-r--r-- 1 nobody nogroup 551023 May 27 14:01 14_20150526065238928590_118.txt
-rw-r--r-- 1 nobody nogroup 60083 May 27 14:01 14_20150526065238928590_119.txt
-rw-r--r-- 1 nobody nogroup 632324 May 28 03:38 14_20150526065238928590_160.txt
-rw-r--r-- 1 nobody nogroup 735624 May 28 03:38 14_20150526065238928590_161.txt
-rw-r--r-- 1 nobody nogroup 2707507 May 28 03:40 14_20150526065238928590_162.txt
From the above list I want to retrieve file names those are created before input date:
For eg: My input date is 20150528, I want the result: (created before 28th of May 2015)
14_20150526065238928590_102.txt
14_20150526065238928590_105.txt
14_20150526065238928590_110.txt
14_20150526065238928590_112.txt
14_20150526065238928590_118.txt
14_20150526065238928590_119.txt
How can I achieve this?

To find all files in the current directory and its subdirectories whose last modification time is earlier than 2015-05-28:
If you only want files from the current directory and not its subdirectories, use:
How it works
find
This is one of unix's most useful commands when searching for files.
.
This tells
find
to start looking in the current directory. You can replace this with any directory that you like.!
This is logical-not: it inverts the test which follows.
-newermt 20150527
This is test for files whose modification time is newer than 2015-05-27. Because of the preceding
!
, this test is inverted and it looks for files not newer than 2015-05-27.Note that "not newer than 2015-05-27" means the same as "created before 28th of May 2015".
