Shell Script — Get all files modified after

Question

I\'d rather not do this in PHP so I\'m hoping a someone decent at shell scripting can help.

I need a script that runs through directory recursively and finds all fil

Answer 1

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

Answer 2

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 -> $f"
        MOD_DATE=$(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) && ($DIFF_IN_DATE1 -le 120) && (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.

Answer 3

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.

Answer 4

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.

Answer 5

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"

Answer 6

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.
