Here is an example which might (or might not) be like what you want:
In[1]:=
square[inputfile_String,outputfile_String]:=
Module[{temp1,temp2},temp1=ReadList[inputfile];
temp2=OpenWrite[outputfile,FormatType->OutputForm];
Write[temp2,temp1^2//TableForm];Close[temp2]]
for example if "numbers" is a file containing the numbers 1,2,3,4
(each on a separate line) then square["numbers","squares"] will give a
file "squares" containing the squares of your numbers, again each on a
separate line. You can vary this to deal with different types of data
in your input file, including numbers separated by commas etc.
