I haven’t yet read through your book Learning Unix for Mac OS X Panther, but I realize now that I probably need to! Here’s what happened: I typed this command “ping www.yahoo.com -f -1 1492” into terminal from a website saying it might help me determine my ideal MTU settings. I believe they mislabeled the instructions and this command should have been for Windows… not Mac.
Did I screw anything up? Here’s what I typed and the results I received:Last login: Sun Oct 17 22:06:55 on console Welcome to Darwin! Wiamea:~ mike$ ping www.yahoo.com -f -1 1492 usage: ping [-Rdfnqrv] [-c count] [-i wait] [-l preload] [-p pattern] [-s packetsize] host Wiamea:~ mike$
Here’s an interesting question I received from a reader:
“In Mac OS X, have you ever done “Get Info” on a shell script, made it
open with Terminal, and had it forcibly execute every time you open the
Terminal app and then exit? Any idea how to fix this? I’ve changed the
path to the script and now it complains that the script is not there but
still forceably exits after failing to execute the original script.”

I have a Mac running OS 10.3.5, and I am trying to use TextEdit to write HTML code in your example. However, it will not let me save the file with an .html extension, as you specify needs to happen for the browsers to properly read it. And I tried it anyway using both .rtf and .txt extensions (the only options it will allow), and Explorer says “it doesn’t know how to handle the type of file you’ve selected.” Of course, I didn’t expect it to work, because your book said it wouldn’t. What can I do? And will I continue encountering problems as I go through your book since I’m working on a Mac, and the book is written from the perspective of PC users? Thanks
A letter came in this morning:
Help! I read about some sort of major security hole where people can exploit the Safari help system and drop junk onto my computer? What’s that all about? How can I avoid it being a danger on my computer?
