For the first script:
echo "$9 $8 $7 $6 $5 $4 $3 $2 $1"
This is not universal and too simple way. I need a script which writes its arguments in the other way round but i don't know how many will be those arguments. That way you wrote me works only with 1 to 9 arguments.
For the second: This is what i looked for

thanx a lot. I didn't know that commend:
I even wrote simpler way (also working)
a=`cat file`
b=`echo -n $a | tr ' ' '+'`
((c=$b))
echo $c
THANX a lot and if you could help me with the first script
