Re: [wlug] Dick Smith's Benq Internal CD-RW. Okay? Okay for Linux?

Well, I have a BenQ/Acer (same thing) CDRW drive in my machine. Works fine. As far as Linux can tell it's just another generic IDE/ATAPI CD drive. I can't tell you how reliable they are though, since mine is somewhat old and doesn't get much of a work out (it's only a 24x speed).

No, but you should be able to find a LiteOn for only $10 or $15 more, which would be my recommendation. -- Matthias

Re: [wlug] Compare 2 directories with each other.

I used to use a shell script that would use diff to compare two directories and all their subdirectories. I mainly used it to verify that a backup CD of crucial data had been written correctly. I have since written it as a perl script which is a bit nicer. Note that I have never got around to tidying up this script to use proper arguments, etc. It currently is set to comparing the current directory to the CD. Edit the line "@totals = &dodir(".","/media/cdrom");" if you want to change the directories it uses. Cut out the script from below and save it as whatever you want to call it and remember to set the execute bit on it. #!/usr/bin/perl # sub dodir { local ($dir) = $_[0]; local ($refdir) = $_[1]; local (@totals) = (0,0,0,0); opendir(F,$dir) || die "ERROR: cannot opendir $dir"; foreach $name (sort readdir(F)) { if ($name ne "." && $name ne "..") { $fullname = $dir . "/" . $name; $refname = $refdir . "/" . $name; if (-d $fullname) { printf "%-50s [d] ", $fullname; if (! -d $refname) { print "ERROR - not on CD\n"; $totals[0]++; }else{ print "(entering)\n"; @subtot = dodir($fullname, $refname); $totals[0] = $totals[0] + $subtot[0]; $totals[1] = $totals[1] + $subtot[1]; $totals[2] = $totals[2] + $subtot[2]; $totals[3] = $totals[3] + $subtot[3]; } }elsif (-f $fullname) { printf "%-50s ... ",$fullname; if (! -f $refname) { print "ERROR - not on CD\n"; $totals[1]++; }else{ $retval = system("cmp -s '$refname' '$fullname'"); if ($retval != 0) { print "ERROR - files differ.\n"; $totals[2]++; }else{ print "OK.\n"; } } }else{ printf "%-50s [can't handle]\n",$fullname ; $totals[3]++; } } } closedir(F); @totals; } $ok = 1; @totals = &dodir(".","/media/cdrom"); print "\n"; if ($totals[3] > 0) { if ($totals[3] == 1) { print "WARNING: There was one [reference] file that I couldn't read.\n"; }else{ print "WARNING: There were $totals[3] [reference] files that I couldn't read.\n"; } } if ($totals[0] > 0) { $ok = 0; if ($totals[0] == 1) { print "WARNING: There was one missing directory.\n"; }else{ print "WARNING: There were $totals[0] missing directories.\n"; } } if ($totals[1] > 0) { $ok = 0; if ($totals[1] == 1) { print "WARNING: There was one missing file.\n"; }else{ print "WARNING: There were $totals[1] missing files.\n"; } } if ($totals[2] > 0) { $ok = 0; if ($totals[2] == 1) { print "WARNING: There was one bad file.\n"; }else{ print "WARNING: There were $totals[2] bad files.\n"; } } if ($ok) { print "All OK.\n"; } Cheers Michael
