Thanks!

Checkout the code below.

#!/bin/sh
if ! test -d $HOME/.Trashcan
   then
   mkdir $HOME/.Trashcan
fi
if test $# -eq 0
  then
    echo $0:missing operand - moron
exit 1
fi
if test $1 = "-r"
  then
  shift
    for stuff in $*
    do
  if test -d $stuff
  then
    mv $stuff $HOME/.Trashcan
      elif test -f $stuff
    then
        mv $stuff $HOME/.Trashcan
fi
done
  else
    for stuff2 in $*
    do
if test -f $stuff2
  then
  mv $stuff2 $HOME/.Trashcan
fi
  if test -d $stuff2
  then
    echo "myrm: cannot remove $stuff2: Is a directory. moron"
fi
done
fi

It uses a simple while loop with if loops nested in it to see if the guessed number is higher or lower than the random number.

#!/bin/sh
#gueessing game
biggest=50
guess=0
guesses=0
number=$(( $$ % $biggest ))
while [ $guess -ne $number ] ; do
echo -n "Guess? " ; read guess
if [ "$guess" -lt $number ] ; then
echo "... bigger!"
elif [ "$guess" -gt $number ] ; then
echo "... smaller!"
fi
guesses=$(( $guesses + 1 ))
done
echo "Right!! Guessed $number in $guesses guesses."
exit 0
