I have used ls in a if loop to know what all are the exists with the yesterday's datestamp...First you have to verify the files and directories and then after you can uncomment the rm command...But please do test it from your end.
And also mentioned the directory name in the commented.
bash-3.00$ find_sterdate.sh
Today is ---> 22-03-2010
Yesterday is ---> 21-03-2010
The complete format in DD-MON-YYYY is ---> 21-Mar-2010
The Script will delete all the files and directories which was created on 21-03-2010
Number of files found to delete ---> 0
Code:
bash-3.00$
bash-3.00$
bash-3.00$ cat find_sterdate.sh
v_todaysdate=`date +%d`
v_yesterday=$((`date +%e` -1))
v_month=`date +%m`
v_year=`date +%Y`
file_cnt1=0
#mention the directory name here like below
#cd /root/myhome/kandir
#tgt_dir=`pwd`
if [ $v_yesterday -eq "0" ]
then
v_month=$((v_month-1))
if [ $v_month -eq "0" ]
then
v_month=12
v_year=$((v_year-1))
fi
set `cal $v_month $v_year`
shift $(($# - 1))
v_yesterday=$1
fi
echo
echo "Today is ---> " $v_todaysdate-$v_month-$v_year
echo
echo "Yesterday is ---> " $v_yesterday-$v_month-$v_year
v_date_format=`/bin/cal $v_month $v_year | grep -v "^$" | sed -n '1p;$p' | tr "\n" " " | awk '{print substr($1,1,3)}'`
echo
echo "The complete format in DD-MON-YYYY is --->" $v_yesterday-$v_date_format-$v_year
echo
echo "The Script will delete all the files and directories which was created on $v_yesterday-$v_month-$v_year"
echo
for file_name1 in `ls -ltr | awk '{print $6,$7,$9}' | grep "$v_date_format $v_yesterday" |awk '{print $3}'`
do
if [ -f $file_name1 ]
then
file_cnt1=`expr $file_cnt1 + 1`
ls -ltr $file_name1
#rm -r $tgt_dir/$file_name1
fi
done
echo
echo "Number of files found to delete --->" $file_cnt1

Try to change the value of the "v_todaysdate" (v_todaysdate = 23) and also verify the code...If the script is giving the results as per the expectations then you can schedule through crontab...First you verify the ode carefully.
I mean to say that if today is 1st of Apr then the script should verify those fiels which were created on 31st Mar..month will be change over here!!!
