Question

hey so I have some code for the question bellow but I am stuck its not working and I don’t really know what I am doing.

This script should remove the contents of the dustbin directory.
If the -a option is used the script should remove ALL files from the dustbin.
Otherwise, the script should display the filenames in the dustbin one by one and ask the user for confirmation that they should be deleted

#!/bin/sh

echo " The files in the dustbin are : "
ls ~/TAM/dustbin

read -p " Please enter -a to delete all files else you will be prompted to delete one    by one : " filename

read ans
if ["filename" == "-a"]
cat ~/TAM/dustbin
   rm -rf*
else
   ls > ~/TAM/dustbin
for line in `cat ~/TAM/dustbin`
do
   echo "Do you want to delete this file" $line
   echo "Y/N"
   read ans
   case "ans" in
      Y) rm $line ;;
      N) "" ;;
esac

EDITED VERSION

 if test ! -f ~/TAM/dustbin/*
then
echo "this directory is empty"
else
for resfile in ~/TAM/dustbin/*
do
   if test -f $resfile ; then
   echo "Do you want to delete $resfile"
   echo "Y/N"
   read ans
   if test $ans = Y ; then 
   rm $resfile
   echo "File $resfile was deleted"
   fi
   fi
done
fi

this works however Now I get one of 2 errors either

line 4 requires a binary operator or line 4: to many arguments

Answer 1

I see one obvious mistake:

rm -rf*

when it should be

rm -rf *

to be asked about every file deletion – add -i key

rm -rfi *
