Find files in created between a date range

Question

I use AIX via telnet here at work  and I d like to know how to find files in a specific folder between a date range  For example  I want to find all files in folder X that were created between 01-Aug-13 and 31-Aug-13   Observations    The touch trick  where you create two empty files to use the -newer option  does not work for me  once the user roles that I have on the server does not allow me to create files  I need to find between specific dates  not days  like  files that were created more than 30 days ago  etc

Use stat to get the creation time  You can compare the time in the format YYYY-MM-DD HH MM SS lexicographically   This work on Linux with modification time  creation time is not supported  On AIX  the -c option might not be supported  but you should be able to get the information anyway  using grep if nothing else works       bin bash from  2013-08-01 00 00 00 0000000000    01-Aug-13 to  2013-08-31 23 59 59 9999999999      31-Aug-13  for file in     do     modified    stat -c y   file        if     from  lt   modified  amp  amp   modified  lt   to      then         echo   file      fi done

Script oldfiles  I ve tried to answer this question in a more complete way  and I ended up creating a complete script with options to help you understand the find command   The script oldfiles is in this repository  To  create  a new find command you run it with the option -n  dry-run   and it will print to you the correct find command you need to use   Of course  if you omit the -n it will just run  no need to retype the find command   Usage     oldfiles  -v       -h -V -n       -a -u     -m -t    -c   -i   -d   -o  -y   -g  N  -  gt    -  lt    -     -p  pat       Where the options are classified in the following groups    Help  amp  Info      -h  --help        Show this help       -V  --version     Show version       -v  --verbose     Turn verbose mode on  cumulative        -n  --dry-run     Do not run  just explain how to create a  find  command    Time type  access use  modification time or changed status       -a or -u         access  use  time      -m or -t         modification time  default       -c               inode status change    Time range  where N is a positive integer       -i N             minutes  default  with N equal 1 min       -d N             days      -o N             months      -y N             years      -g N             N is a DATE  example   2017-07-06 22 17 15      Tests      -p  pat          optional pattern to match  example  -p    c  to find c files   default -p           -                file is newer than given range  ie  time modified after it       -  lt               file is older than given range  ie  time is from before it   default       -                file that is exactly N  min  day  month  year  old      Example    Find C source files newer than 10 minutes  access time   with verbosity 3        oldfiles -a -i 10 -p   c  -  gt  -nvvv Starting oldfiles script  by beco  version 20170706 202054      oldfiles -vvv -a -i 10 -p    c  -  gt  -n Looking for    c  files with  a ccess time newer than 10 minute s  find   -name    c  -type f -amin -10 -exec ls -ltu --time-style long-iso      Dry-run    Find H header files older than a month  modification time   verbosity 2        oldfiles -m -o 1 -p   h  -  lt  -nvv Starting oldfiles script  by beco  version 20170706 202054      oldfiles -vv -m -o 1 -p    h  -  lt  -n find   -name    h  -type f -mtime  30 -exec ls -lt --time-style long-iso      Dry-run    Find all     files within a single day  Dec  1  2016  no verbosity  dry-run        oldfiles -mng  2016-12-01  -   find   -name     -type f -newermt  2016-11-30 23 59 59    -newermt  2016-12-01 23 59 59  -exec ls -lt --time-style long-iso        Of course  removing the -n the program will run the find command itself and save you the trouble   I hope this helps everyone finally learn this  a c t  time min  options   the LS output   You will also notice that the  ls  option ls OPT changes to match the type of time you choose   Link for clone download of the oldfiles script   https   github com drbeco oldfiles

Explanation  Use unix command find with -ctime  creation time  flag  The find utility recursively descends the directory tree for each path listed  evaluating an expression  composed of the  primaries  and  operands   in terms of each file in the tree   Solution  According to documenation  -ctime n smhdw               If no units are specified  this primary evaluates to true if the difference              between the time of last change of file status information and the time find              was started  rounded up to the next full 24-hour period  is n 24-hour peri-              ods                If units are specified  this primary evaluates to true if the difference              between the time of last change of file status information and the time find              was started is exactly n units   Please refer to the -atime primary descrip-              tion for information on supported time units    Formula  find  lt path gt  -ctime   number  timeMeasurement  -ctime - number  timeMeasurment   Examples   1 Find everything that were created after 1 week ago ago and before 2 weeks ago  find   -ctime  1w -ctime -2w  2 Find all javascript files   js  in current directory that were created between 1 day ago to 3 days ago  find   -name     js  -type f -ctime  1d -ctime -3d

If you use GNU find  since version 4 3 3 you can do   find -newerct  1 Aug 2013    -newerct  1 Sep 2013  -ls   It will accept any date string accepted by GNU date -d   You can change the c in -newerct to any of a  B  c  or m for looking at atime birth ctime mtime   Another example - list files modified between 17 30 and 22 00 on Nov 6 2017   find -newermt  2017-11-06 17 30 00    -newermt  2017-11-06 22 00 00  -ls   Full details from man find      -newerXY reference           Compares the timestamp of the current file with reference   The reference argument is normally the name of a file  and one of its timestamps  is  used           for  the  comparison   but  it may also be a string describing an absolute time   X and Y are placeholders for other letters  and these letters select           which time belonging to how reference is used for the comparison             a   The access time of the file reference           B   The birth time of the file reference           c   The inode status change time of reference           m   The modification time of the file reference           t   reference is interpreted directly as a time            Some combinations are invalid  for example  it is invalid for X to be t   Some combinations are not implemented on all systems  for example B  is  not           supported on all systems   If an invalid or unsupported combination of XY is specified  a fatal error results   Time specifications are interpreted as           for the argument to the -d option of GNU date   If you try to use the birth time of a reference file  and the birth time cannot be determined  a fatal           error  message  results    If  you  specify a test which refers to the birth time of files being examined  this test will fail for any files where the           birth time is unknown

You can use the below to find what you need   Find files older than a specific date time   find    -mtime   echo   date   s  -   date   s -d Dec 31  2009 23 59 59     bc -l   awk   print  1   86400     bc -l    Or you can find files between two dates  First date more recent  last date  older  You can go down to the second  and you don t have to use mtime  You can use whatever you need   find   -mtime   date   s -d Aug 10  2013 23 59 59   -mtime   date   s -d Aug 1  2013 23 59 59
