Assume that more than nine arguments can be passed to the program.

Question

Using eval, write a program called recho that prints its arguments in reverse order. So
recho one two three

should produce
three two one

Answer 1

# recho - reverse echo using eval

count=$# # number of args given

while [ $count -gt 0 ]
do
eval echo "\$$count \\\c"
count=$(( $count - 1 ))
done

echo "" # end of line
