ruby -e 'Dir.glob("*").each { |fn| File.rename(fn, fn.downcase) }'
Obviously this would work with method #upcase as well.

For some reason, the "-o" option is missing from netstat on OS X Snow Leopard (10.6.4, anyway), so if you need to know which processes are using a given port, try:
sudo lsof -i -P | grep 36364
Of course substitute your own port number (36364 is used by Skype, btw).

chuck: http://chuck.cs.princeton.edu/
ngrep: http://ngrep.sourceforge.net/
Using chuck and ngrep, you can translate the ascii output of ngrep into midi sounds in real time by reading from a file with chuck which is being appended by ngrep:
sudo ngrep -d en1 '' > network
chuck listen.ck < network
listen.ck source:
// computer key input, with sound
KBHit kb;
// patch
Impulse i => BiQuad f => dac;
// set the filter’s pole radius
.99 => f.prad;
// set equal gain zeros
1 => f.eqzs;
// initialize float variable
0.0 => float v;
// set filter gain
.5 => f.gain;
// time-loop
while( true )
{
// wait on event
kb => now;
// generate impulse
1.0 => i.next;
// loop through 1 or more keys
while( kb.more() )
{
// set filter freq
kb.getchar() => int c;
if(c < 58) 58 %=> c;
if(c > 120) 120 %=> c;
c => Std.mtof => f.pfreq;
// print int value
<<< “ascii:”, c >>>;
}
}Sounds a bit like a colorful geiger counter.
Maybe you can ngrep for something specific and learn to recognize the sound of it amongst other traffic.

Fine, then, we'll use Perl. OUTTA THA WAY!!!!!
Remove pesky windows carriage returns:
perl -pi.bak -e 's/\r/\n/g;' ./thefile

Turn a list into quoted comma separated values for a perl array:
perl -i.bak -ne 's/^(.*?)\n$/\"$1\",/;print' ./list_of_bare_strings
Oh, but your list is just a bunch of filenames you copied from the output of 'ls' and you need them one-per-line:
printf "%s\n" $(>pasted_ls_output) < list_of_bare_strings
