Answer 1

#!/bin/bash
set -u
greeting="Hello"
name=$1 #need to remove spaces in between words and =
if [[ -z $name ]]; then
echo "You need to tell me your name!"
echo " $0 "
exit -1
else
echo "$greeting $name" #need greeting word here because we have used above not greetig
fi
i=0 # need to initialize the i value because we are comparing with < 4 in while loop
while [[ $i < 4 ]]; do
echo "i is currently $i"
i=$((i+1));
set +u
done #need this to complete the loop
exit 0
