I would simply do the following to backup all new files from 7 days ago

tar --newer $(date -d'7 days ago' +"%d-%b") -zcf thisweek.tgz .

note you can also replace '7 days ago' with anything that suits your need

Can be : date -d'yesterday' +"%d-%b"

Or even : date -d'first Sunday last month' +"%d-%b"

This will work for some number of files  You want to include  -print0  and  xargs -0  in case any of the paths have spaces in them  This example looks for files modified in the last 7 days  To find those modified before the last 7 days  use   7     find   -mtime -7 -print0   xargs -0 tar -cjf  foo archive tar bz2   As this page warns  xargs can cause the tar command to be executed multiple times if there are a lot of arguments  and the  -c  flag could cause problems  In that case  you would want this   find   -mtime -7 -print0   xargs -0 tar -rf  foo archive tar   You can t update a zipped tar archive with tar  so you would have to bzip2 or gzip it in a second step

well  under linux try reading man page of the find command  man find   something like this should    find   -type f -mtime -7 -print -exec cat         tar cf -   gzip -9   and you have it

You can get a list of files last modified later than x days ago with   find   -mtime -x   Then you just have to tar and zip files in the resulting list  e g    tar czvf mytarfile tgz  find   -mtime -30    for all files modified during last month

as simple as   find   -mtime -1   xargs tar --no-recursion -czf myfile tgz   where find   -mtime -1 will select all the files in  recursively  current directory modified day before  you can use fractions  for example   find   -mtime -1 5   xargs tar --no-recursion -czf myfile tgz

This script will find files having a modification date of two minutes before and after the given date  and you can change the values in the conditions as per your requirement   PATH SRC   home celvas Documents Imp Task   PATH DST   home celvas Downloads zeeshan    cd  PATH SRC TODAY   date  -d    date   F     s  TODAY TIME   date -d    date   T     s    for f in  ls   do         echo  File - gt   f          MOD DATE   stat -c  y   f           MOD DATE   MOD DATE             echo MOD DATE   MOD DATE         MOD DATE1   date -d   MOD DATE    s          echo MOD DATE   MOD DATE  DIFF IN DATE     MOD DATE1 -  TODAY   DIFF IN DATE1     MOD DATE1 -  TODAY TIME    echo DIFF   DIFF IN DATE  echo DIFF1   DIFF IN DATE1 if      DIFF IN DATE -ge -120   amp  amp    DIFF IN DATE1 -le 120   amp  amp   DIFF IN DATE1 -ge -120     then echo File lies in Next Hour    f echo MOD DATE   MOD DATE   mv  PATH SRC  f   PATH DST  f fi done   For example you want files having modification date before the given date only  you may change 120 to 0 in  DIFF IN DATE parameter discarding the conditions of  DIFF IN DATE1 parameter   Similarly if you want files having modification date 1 hour before and after given date  just replace 120 by 3600 in if CONDITION

This should show all files modified within the last 7 days   find   -type f -mtime -7 -print   Pipe that into tar zip  and you should be good

You can do this directly with tar and even better   tar -N  2014-02-01 18 00 00  -jcvf archive tar bz2 files   This instructs tar to compress files newer than 1st of January 2014  18 00 00

If you have GNU find  then there are a legion of relevant options   The only snag is that the interface to them is less than stellar    -mmin n  modification time in minutes  -mtime n  modification time in days  -newer file  modification time newer than modification time of file  -daystart  adjust start time from current time to start of day  Plus alternatives for access time and  change  or  create  time    The hard part is determining the number of minutes since a time   One option worth considering  use touch to create a file with the required modification time stamp  then use find with -newer   touch -t 200901031231 43  tmp wotsit find   -newer  tmp wotsit -print rm -f  tmp wotsit   This looks for files newer than 2009-01-03T12 31 43   Clearly  in a script   tmp wotsit would be a name with the PID or other value to make it unique  and there d be a trap to ensure it gets removed even if the user interrupts  and so on and so forth
