Why are you using cat? Even if awk couldn't read files, you could do this:
Code:
awk '/^Number of records loaded/{print $NF}' <file

But the proper way is
Code:
awk '/^Number of records loaded/{print $NF}' file

@futurelet .. i agree.. that's what i settled into finally (taking a lead from solea, of course) ..

(...i guess that's all i should post in this thread lest i should be charged of hijacking other's threads... thanks a lot guys :-) )

Code:
value=`sed -n '/Number/p' file | sed -e 's/^.*= //'`
echo $value

Also you can discard the first 4 or the last 4.
Code:
last_part=${x#????}
first_part=${x%????}
echo $first_part  $last_part

Perderabo,

I used the ${x#????} and ${x%????} and they worked like majik ...
I wonder where I can learn more about this technique Smilie

Thanks alot!
