Thanks, Park. I’ll give this code a try.
I’m a newbie, but its clear I need to get a more advanced Ruby guide before I can do this level of coding (even though I’m sure its elementary) on my own.
Question: I’ve seen the “for line in file” in program samples like the one below. What’s there a reason why this line-stepping technique would not have worked in my application?
# Count the words in a file # 1
# 2
filename = ARGV.shift # 3
words = 0 # 4
file = open(filename) # 5
for line in file # 6
words += line.split.length # 7
end # 8
file.close # 9
# 10
puts "Word Count: #{words}" # 11
I appreciate your help!

FileA using names from FileB?
Hi,

All-
I’d be grateful for a jumpstart on this problem:
I have two text files “FileA” and “FileB”. FileB contains many lines, each
line has three colon delimted fields (field1, field2, field3). What I want
to do is step through FileB line-by-line, replace some text in FileA with
the values in the field2 and field3 fields of FileB, and save the modified
FileA with a file name that comes from the text in field1 of FileB.
I think you want this code, don’t you?
content = File.new(“FileA”).read
IO.foreach(“FileB”) { |x|
field = x.chop.split(‘:’)
content2 = content
modify content2 here
File.new(field[0],“w+”).write(content2)
}
