Insert two strings at the beginning and at the end of each line of a file

Hi, excuse me for my poor english.
My problem is that:

I have a File
i want to add to each line of that file two strings: one at the beginning of the line, one at the ending.

string1="abcd"
string2="efgh"

i want $string1 content $string2 for each line.
Is that possible?

Code:
awk '{ print "abcd", $0, "efgh" } ' inputfilename> tmp.tmp
# with variables
awk -v string1="$string1" -v string2="$string2" '{ print string1, $0, string2 } ' inputfilename> tmp.tmp

mv tmp.tmp inputfilename

thank you very much for the quick reply. It works flawlessly Smilie

I'd like to know also how to remove the spaces between content and strings inserted if it's possible

Thanks again Smilie
