I need to add a value to the 25th item in each line. Other than knowing

numeric and 10 characters long, I don't know anything more about it.

running the command: sed -n -e '/text/p' "log _20090814_162009" | awk '{print $25}' gives: 1363231555 ...

I need to able to make them look like: 1000000001363231555 ...

Just prepend it to the field before printing them:

awk '{$25="100000000"$25; print}'

for example:

mak@yoda:~$ echo "a 1363231555 c d" | awk '{$2="100000000"$2; print}' a 1000000001363231555 c d
