File Auditing with rails - File I/O issue

Rails
1

Hey Folks,
I’ve written a script to generate a list of all files on a machine,
then zip the results. I’m going to stick a web front end on it, and use
it to audit some file servers. The problem is that the ZIP
compression/decompression isn’t working,
but its not what you might think. The script completes, but seems to
not actually write anything.

Here is a short version that only looks at the C:/temp drive. You can
change this at the top.

—Start Code Here–
require ‘find’
require ‘csv’
require ‘zlib’
tempfile = “temp.csv”
outfile = “out.zip”
dirname = “c:/temp”

Prepare comma-delimited file for writing

CSV::Writer.generate(File.open(tempfile,“w+”), ‘,’) do |csv|
Find.find(dirname) do |f|
csv << [File.dirname(f), File.basename(f), File.mtime(f).to_s]
end
end

TEST: View the tempfile to make sure it has data.

This prints nothing, but the file DOES have info after

the script completes. Maybe the file isn’t written at this point?

p IO.read(tempfile)
Zlib::GzipWriter.open(outfile) do |gz|
gz << File.open(tempfile).read
end
Zlib::GzipReader.open(outfile) {|gz|
print gz.read
}

The ZIP file can’t be extracted with WINZIP. No idea why, but since

I’ll be using another RUBY script for extraction, im not sure that I

care.

I think you might want to try

outfile = “out.gz”
…
Zlib::GzipWriter.open(outfile) do |gz|
gz.write(File.read(tempfile))
end

also, gzip != zip hence why winzip can’t do anything with the resulting
gzipped file. I wouldn’t know if winzip supports gzip compression or
not.
the extension for a gzipped file is typically .gz.
