Shell Programming and Scripting

New to scripting in general, so patience plz. If I ask a stupid question or don't get it, I thank you for your kindness in advance.

That said, did a for i loops checks to see if a PB* file is there but I need to know two things before I copy the file.

I need to know if the file's create date is = to today and I also need to make sure I haven't copied it into the directory already. If I've already copied in the directory no need to copy it there again etc?

#!/bin/bash
oklist=`cat /export/home/jay01/scripts/oklist.txt`
for i in $oklist;
do
CHECKFILE="$(find /apps/migrate/output/rtdata/$i/Downloaded/ -name PB*)"
if [ -n "${CHECKFILE}" ]
then
echo "***************************************************************"
echo `date`
ls -ltr /apps/migrate/output/tdata/$i/Downloaded/
echo "***************************************************************"
cp -p /apps/migrate/output/tdata/$i/Downloaded/* /apps/migrate/usops/okdownload/
else
echo "***************************************************************"
echo " No Files to move in /apps/migrate/output/tdata/`echo $i`/Downloaded/ "
echo "***************************************************************"
fi
done;

Ok how about I take out create date = today --- and just do if it's in the downloaded folder I don't want to repeat a copy.

I'm reposting it reformatted so it's easier to understand...

Code:

#!/bin/bash
oklist=`cat /export/home/jay01/scripts/oklist.txt`
for i in $oklist
do
    CHECKFILE="$(find /apps/migrate/output/rtdata/$i/Downloaded/ -name PB*)"
    if [ -n "${CHECKFILE}" ]
    then
        echo "***************************************************************"
        echo `date` 
        ls -ltr /apps/migrate/output/tdata/$i/Downloaded/
        echo "***************************************************************" 
        cp -p /apps/migrate/output/tdata/$i/Downloaded/* /apps/migrate/usops/okdownload/
    else
        echo "***************************************************************"
        echo " No Files to move in /apps/migrate/output/tdata/`echo $i`/Downloaded/ "
        echo "***************************************************************"
    fi
done

now remember 'find' can return multiple answers, my general pattern with find is

Code:

find /apps/migrate/output/rtdata/$i/Downloaded -type f -name "PB*" | while read CHECKFILE
do
      if test -f "$CHECKFILE"
      then
                whatever
      fi
done
