Any idea what these scripts do?

Any idea what these scripts do? I coudn't get the count command to work. :(

#!/bin/bash
string="The quick brown fox jumped over the lazy dog"
for i in `count 5 20`
do
echo $string | cut –c $i
done

#!/bin/bash
low_val=$1;high_val=$2
while [ $low_val -le $high_val ]
do
echo -n $low_val " "
low_val=`expr $low_val + 1`
done

This is a question we had in class today and no one knew.

They are made for walking up a ladder from the fist step ( val_low ) to the top ( val_high ) and printing the results.

This is the ladder for the first part
low_val=`expr $low_val + 1`

This is the ladder for the second part
for((i=5; i<=$high_val; i++))

You can't use $low_val here as it is actually a much higher value than you might expect. You can show that by putting a couple of echos statements in the code ....
echo $low_val
echo $high_val
for((i=5; i<=$high_val; i++))

Code:

#!/bin/bash



low_val=5;high_val=20

while [ $low_val -le $high_val ]

do

echo -n $low_val " "

low_val=`expr $low_val + 1`

done



echo ""

string="The quick brown fox jumped over the lazy dog"

for((i=5; i<=$high_val; i++))

do

echo $string |cut -c $i

done

Or don't make two identical posts in two different forums!

It wasn't homework, just a question that was posed and I apologize for any headaches.
