Code:
 
#!/bin/bash
(
for I in {1}
do
/usr/bin/time -f "%E"  ~/oblig1/oblig1a.sh >/dev/null  2>&1 
done | while IFS=":." read MIN SEC TENTH
do
printf " %s " "( ( $MIN * 60) * $SEC ) +"
done
)

doesnt return anything atm tho.

Probably because you're still redirecting the output you need...

How about this: Save it in a temp file then use that file.

Code:
#!/bin/bash
for I in {1}
do
        /usr/bin/time -f "%E"  ~/oblig1/oblig1a.sh
done 2> timefile

(       while IFS=":." read MIN SEC TENTH
        do
                printf " %s " "( ( $MIN * 60) * $SEC ) +"
        done

        echo "0" # Print the last number so it's ...+0.  Also, a newline.
) < timefile | bc

Also: "for I in {...}" is inefficient and prone to breaking when you run out of arguments. how about:

Code:
for ((I=0; I<10; I++))
do
...
done

Code:
 
(standard_in) 1: syntax error
(standard_in) 1: illegal character: :

without | bc

Code:
~/oblig1$ bash oblig2.sh
 ( ( oblig2.sh: * 60) * line ) +  ( ( oblig2.sh: * 60) * line ) +  ( ( oblig2.sh: * 60) * line ) +  ( ( oblig2.sh: * 60) * line ) +  ( ( oblig2.sh: * 60) * line ) + 0

Your script is chattering junk into stderr, you need to fix the errors in your script before you'll have clean output to put into bc.

It was a silly question anyway. :/ You solved it hours ago and more easily, just with the 'wrong' tool.
