printf("%f.11\n",a)

The ".11" addition only adds it in the end of the number. Like this:

Code:
-3841.924102.11

I'll try the pearl advice aswell.

If I use the script:

Code:
perl -lne '{chomp;$x+=$_}END{print $x}' f2

alone, then it works, but if I add it to the other row's then it never finishes. My complete sh script is:

Code:
grep 'zero point VIBRATIONAL energy' */* > nr001.txt
grep 'total energy' > nr002.txt
awk 'NR==FNR {print $8; next} {print $6}' nr001.txt nr002.txt > nr003.txt
perl -lne '{chomp;$x+=$_}END{print $x}' nr003.txt > nr004.txt
