simple script help

TZ=`date +%Z`+24 ; a=`date +%Y-%m-%d`-----------greps 1 day ago date........

but this command greps date in files for 1 day ago date........even the current date is found inside the file.....

is there any logic using this command that it will grep the last date entry made in file ,whether it is current date or 1 day ago date or 2 day and likewise ?

here is the script

TZ=`date +%Z`+24 ; a=`date +%Y-%m-%d`

for i in *.log*
echo "Processing for $i"
count=`cat $i | grep $a | wc -l`
echo $i >> file1.txt
echo "the last date entry made in file1 is $a" >> file1.txt

Yiou can find out the latest day and month by using the following command :

day=`ls -lrt *.log | tail -1 | awk '{printf("%2d",$7)}'`
mon=`ls -lrt *.log | tail -1 | awk '{print $6}'`

for file in `ls -l *.log | grep "$mon $day"

I couldn't get your question,by the way why "cat filename | grep date" while "grep date filename" can do the same job much efficiently?
