Want to Zip files based on modified date

Question

A file (Paths.dat) which contains multiple Paths where it needs to find files which are 15 days old and zip it in same folder with modified date.

Paths.dat :- contains multiple paths in File system ( with delimiter ' | ' )

/docusr1/user01 | /docusr2/user02 | /home/user01

ex:- /docusr1/user01

-rwxrwxrwx. 1 docusr2 docusr2     0 Mar 30 10:52 vinay.txt
-rw-rw-r--. 1 docusr2 docusr2     0 Mar 30 10:52 sathish.txt
-rw-rw-r--. 1 docusr2 docusr2   625 Apr  2 10:57 demo1.xml
-rw-rw-r--. 1 docusr2 docusr2  4430 Apr  2 11:09 sample.xml
-rw-rw-r--. 1 docusr2 docusr2    48 Apr  2 14:04 20180402140454.log
-rw-rw-r--. 1 docusr2 docusr2    48 Apr  2 14:39 20180402143917.log
-rw-rw-r--. 1 docusr2 docusr2    39 Apr  2 14:41 20180402144159.log
-rw-rw-r--. 1 docusr2 docusr2    84 Apr  2 14:46 20180402144651.log
-rw-rw-r--. 1 docusr2 docusr2   279 Apr  2 14:48 archive.sh
-rw-rw-r--. 1 docusr2 docusr2    84 Apr  2 14:48 20180402144814.log
-rw-rw-r--. 1 docusr2 docusr2  1228 Apr  5 10:10 real.xml

search for files which are 15 days old and need to zip the files with modified date as zip file name(archive file)

o/p expected:-

20170330.zip  -> it should contain all file which are modified on 2017-03-30
20170402.zip
20170405.zip

Answer 1

find . -maxdepth 1 -mtime +15 -type f -printf "%TY%Tm%Td %p\n" | while read date name ; do zip $date $name; done

File's last modification time in Ymd format

To do it for all underneath directories, there are different ways to do it, giving below a few, make sure to use absolute path with find, for example I use "/home/user"

find /home/user -type d -print0 | while read -d '' -r dir; do cd "$dir" && pwd && find . -maxdepth 1 -mtime +15 -type f -printf "%TY%Tm%Td %p\n" | while read date name ; do zip $date $name; done; done

or

find /home/user -type d -print0 | xargs -0 -I {} sh -c 'cd '\"{}\"' && pwd && find . -maxdepth 1 -mtime +15 -type f -printf "%TY%Tm%Td %p\n" | while read date name ; do zip $date $name; done'

Answer 2

You can try the following:

while read zipfile files; do 
    zip ${zipfile}.zip $files
done <<< $(find -maxdepth 1 -type f | xargs stat -c "%y,%n" | awk -F, '{a[substr($1,1,10)]=a[substr($1,1,10)] " " $2} END{for(i in a){print i a[i]}}')

The while loop expects strings with the following format:

zipfilename file1 file2 file3 ...

This is achieved by

• getting all regular files of the current directory: find -maxdepth 1 -type f
• looking at the modification time using stat
• formating the result using awk such that all files modified that day are listed in one line
