Shell - Replace

Hello ,

I am trying to replace a pattern in shell script , basically there is a file with the list of tables like
C.DAT ..

I will need to replace a prefix for the list


Do I need to use <tr> or sed , I am not sure whether I need to use awk to get the print $1 , in my case it's always one string

awk '{ print "TEST" $0 }' < infile > outfile

$0 is a special variable in awk which means 'the entire line'.
