Standardizing the time in the script

Hi,

I have created a script to generate a report 3 times every month.
Part of the script transfers files from one directory to the other.
These files span from a certain time range, like from the 2nd onwards, 8th onwards, and 16th onwards.
Therefore, for the first report of the month, if the team requests to start generating the report on the 4th, then I will have to copy files dated 2nd of the month to 4th of the month to another directory.

This is the command I use to transfer the file; eg for Jun :

Code:
mkdir -p /var/log/exim4/$YEAR/$DIR1
find . -type f -name 'mainlog.*' -newermt "Jun 2, 2017" ! -newermt "Jun 4, 2017" -exec cp {} $YEAR/$DIR1/ \;

What if I want this pattern every month? How and what do I substitute Jun 2, 2017 and Jun 4, 2017 with?

I know that we can use the -d option for date to display time described by STRING, not `now'.

Is it possible to use this option to display the date as 2nd of the month every month?

Example using this option :
Code:
date +"%Y-%m-%d" -d "8 days ago"

# 2  
Have you considered getting the year & month from the date command and forcing the day as a literal?

I'm not really clear what you are trying to achieve, but would this help?
Code:
date +"%Y-%m-02" -d "8 days ago"

If you are actually trying to use find, then if you can get the date in the correct format, then you can create a reference file to work from. Have a look at this and see if you can adjust it to your needs:-
Code:
ref_date_start=($date +%Y%m020000 -d "8 days ago")
ref_date_end=($date +%Y%m020000 -d "3 days ago")

touch -mt $ref_date_start /tmp/start_ref_file
touch -mt $ref_date_end /tmp/end_ref_file

find /path/to/search -newer /tmp/start_ref_file ! -newer /tmp/end_ref_file


I hope that this ends, but my apologies, sir/madam, if I've completely got confused. Smilie

Hi,

Thanks for your reply.
The info you gave on using "date +"%Y-%m-02" works. Means it shows the date as 2017-07-02.

I tested out running the command like this, and it seems like it lists down files :

Code:
root@L28mustang:/var/log/exim4# SECOND=$(date +"%Y-%m-02")
root@L28mustang:/var/log/exim4# NOW=$(date +"%Y-%m-%d")
root@L28mustang:/var/log/exim4# find . -type f -name 'mainlog.*' -newermt $SECOND ! -newermt $NOW -ls

root@L28mustang:/var/log/exim4#

To confirm properly if indeed the latest file for the current date is listed, I run this command :

Code:
root@L28mustang:/var/log/exim4# find . -type f -name 'mainlog.*' -newermt $NOW -ls
5769924 27424 -rw-r-----   1 Debian-exim adm      28074686 Jul 13 06:25 ./mainlog.1
root@L28mustang:/var/log/exim4#

It lists down a file with the current date, however when I check how many files with the current date exist :

Code:
-rw-r-----  1 Debian-exim adm 28074686 Jul 13 06:25 mainlog.1
-rw-r-----  1 Debian-exim adm 13412149 Jul 13 17:40 mainlog
root@L28mustang:/var/log/exim4#


There are 2 files. Why does it not list down the 2nd file with the time 17:40 in the former command?
