Unix Loop if Condition and exit comand - unix

Question

I am facing an issue, I have to delete files from some folders given in Path.lst,
The entire script is working fine but when some wrong path is given in Path.lst the script does exits out of the loop and perform no operation on the next paths.
But the last line
echo -e "\n ENDING SCRIPT SUCCESSFULLY ON `date` " >> $LOG_FILE
gets executed because exit 1 is not working in this part
if [ ! -d $path ]
then
echo -e "\nERROR :$path IS INVALID." >> $LOG_FILE
echo -e "\nENDING SCRIPT WITH ERRORS ON `date`" >> $LOG_FILE
exit 1
---------------------------------------------------------------------------------------
THE SCRIPT IS LIKE :
echo -e "\nSTARTING SCRIPT ON `date`">> $LOG_FILE
if [ $1 -gt 0 ]
then
DAYS_BFOR="$1"
else
echo -e "\nERROR :Please pass a single positive integer to the script" >>$LOG_FILE
echo -e "\nENDING SCRIPT WITH ERRORS ON `date` " >> $LOG_FILE
exit
fi
cat Path.lis | sed 's|^PATH[0-9]*=||g' | while read path
do
if [ ! -d $path ]
then
echo -e "\nERROR :$path IS INVALID." >> $LOG_FILE
echo -e "\n ENDING SCRIPT WITH ERRORS ON `date` " >> $LOG_FILE
exit 1
else
echo -e "\nFILES DELETED FROM THE "$path" DIRECTORY --" >> $LOG_FILE
find $path -type f -mtime +$DAYS_BFOR -printf "%TY-%Tm-%Td %kKB %p\n" | column -t | sed "s|"$path"||g" >> $LOG_FILE 2>&1
file_count=`find $path -type f -mtime +$DAYS_BFOR | wc -l`
if [ $file_count -ge 1 ]
then
find $path -type f -mtime +$DAYS_BFOR | xargs rm 2>>$LOG_FILE 2>&1
fi
fi
done
echo Exit Status : $?
echo -e "\n ENDING SCRIPT SUCCESSFULLY ON `date`" >> $LOG_FILE
Please help and explain the reason as well.

If you only want the "ENDING SCRIPT SUCCESSFULLY" message to appear if files were successfully deleted, not if an invalid path was given you could just move the last two echo lines up to the end of the else statement like this:
else
echo -e "\nFILES DELETED FROM THE "$path" DIRECTORY --" >> $LOG_FILE
find $path -type f -mtime +$DAYS_BFOR -printf "%TY-%Tm-%Td %kKB %p\n" | column -t | sed "s|"$path"||g" >> $LOG_FILE 2>&1
file_count=`find $path -type f -mtime +$DAYS_BFOR | wc -l`
if [ $file_count -ge 1 ]
then
find $path -type f -mtime +$DAYS_BFOR | xargs rm 2>>$LOG_FILE 2>&1
fi
echo Exit Status : $?
echo -e "\n--------------------------- ENDING SCRIPT SUCCESSFULLY ON `date` ----------------------------------" >> $LOG_FILE
fi
done
If you want to just skip to the next item in the Path.lis file then just remove the exit statement from the first loop. That way it will continue to execute the script until all the lines in the file have been read, and just show an error if the current file is not a valid path.
