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.txtFrom 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.txt14_20150526065238928590_105.txt14_20150526065238928590_110.txt14_20150526065238928590_112.txt14_20150526065238928590_118.txt14_20150526065238928590_119.txtHow can I achieve this?
Get all filenames in a directory created before input date

To find all files in the current directory and its subdirectories whose last modification time is earlier than 2015-05-28:find . ! -newermt 20150527If you only want files from the current directory and not its subdirectories, use:find . -maxdepth 1 ! -newermt 20150527How it worksfindThis 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 20150527This 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.
