Unix script for checking logs for last 10 days - shell

Question

I have a log table which is maintained for a single day and the data from the table is only present for one day.However, the logs for it is present in the unix directory.
My requirement is to check the logs for the last 10 days and find me the count of records got loaded.
In the log file the pattern is something like this( fastload log of teradata).
**** 13:16:49 END LOADING COMPLETE
Total Records Read = 443303
Total Error Table 1 = 0 ---- Table has been dropped
Total Error Table 2 = 0 ---- Table has been dropped
Total Inserts Applied = 443303
Total Duplicate Rows = 0
I want to the script to be parametrized( parameter will be stage table name) which find the records inserted into table and error tables for the last 10 days.
Is this possible? Can anyone help me build the unix script for this?
There are many logs in the logs directory. what if a want to check only for the below:
bash-3.2$ ls -ltr 2018041*S_EVT_ACT_FLD*
-rw-rw----+ 1 edwops abgrp 52610 Apr 10 17:37 20180410173658_S_EVT_ACT_FLD.log
-rw-rw----+ 1 edwops abgrp 52576 Apr 11 18:12 20180411181205_S_EVT_ACT_FLD.log
-rw-rw----+ 1 edwops abgrp 52646 Apr 13 18:04 20180413180422_S_EVT_ACT_FLD.log
-rw-rw----+ 1 edwops abgrp 52539 Apr 14 16:16 20180414161603_S_EVT_ACT_FLD.log
-rw-rw----+ 1 edwops abgrp 52538 Apr 15 14:15 20180415141523_S_EVT_ACT_FLD.log
-rw-rw----+ 1 edwops abgrp 52576 Apr 16 15:38 20180416153808_S_EVT_ACT_FLD.log
Thanks.

Answer 1

find . -ctime -10 -type f -print|xargs awk -F= '/Total Records Read/ {print $2}'|paste -sd+| bc
find . -ctime -10 -type f -print get the filenames of files 10 days or younger in current working directory. To run on a different directory replace . with the path
awk -F= '/Total Records Read/ {print $2}' using = as a field seperator filter out the second half of any line containing the key phrase
Total Records Read
paste -sd+ add a plus sign
bc evaluate the stream of numbers and operators into a single answer

Answer 2

I could not use find. because the system is Solaris, find doesn't have maxdepth future. I use case to create a FILTER2 and use it to
ls -l --time-style=long-iso FOLDER | grep -E $FILTER.
but I know it's not a good way.
LOCAL_DAY=`date "+%d"`
LOCAL_MONTH=`date "+%Y-%m"`
LASTTENDAYE_MONTH=`date --date='10 days ago' "+%Y-%m"`
case $LOCAL_DAY in
0*)
FILTER2="$LASTTENDAY_MONTH-[2-3][0-9]|$LOCAL_MONTH";;
1*)
FILTER2="$LOCAL_MONTH-0[0-9]|$LOCAL_MONTH-1[0-9]";;
2*)
FILTER2="$LOCAL_MONTH-1[0-9]|$LOCAL_MONTH-2[0-9]";;
