Error
How would I read in values from a text file and do the exact thing?

Text file contains 2 values: test.txt

1.51 -2.76

I want to read these values from test.txt and assign them to numone and numtwo:

# !bin/bash
numone=test.txt-value1
numtwo=test.txt-value2
total=`echo $numone + $numtwo | bc`
echo $total
# 5

Code:
#!/bin/ksh

read numone numtwo < test.txt
total=$(echo "scale=2; ${numone} + ${numtwo}" | bc)

echo "[${numone}] + [${numtwo}] = [${total}]"

For the future, pls create a new thread for the unrelated questions.
