Adding Strings to a file

Well thanks a lot but I have another Problem
I try to solve.

I habe one simple Textfile
with entries like this, for example:
file1
file2
file3
file4
...
file200

And I want to add Strings at the beginning on the line.
Like this
word1 file1
word1 file2
...

I hope you can help me

sincerely,
Blackbox

create a loop to read the file line by line, and then you can do anything to the lines inside the loop:

cat myfile | while read line
do
echo "word1 $line" >> mynewfile
done

uuoc !

cp myfile myfile.bak
while read line
do
   echo "word1 $line" >> myfile
done < myfile.bak

or use sed

sed -i 's/^/word1 /' myfile
awk '{print "word1 " $0}' myfile >>newfile
