then she certainly forgot the -v switch. I realize your reply was a joke, but the -v switch is not necessary. It only turns on verbose mode. In some cases, using -v is actually detrimental. For example, when unpacking any modern Linux kernel, there are so many small files that it takes longer to print their name to the screen than it does to unpack them. Turning on -v causes it to take longer than it does otherwise.	[reply]

Actually, even on very fast connections, the time to download dwarfs the time to decompress, untar, or print the names. The best way is `tail -f -n+0 linux-n.n.n.tar.bz2\|bzcat -vv\|tar -xv`.

This is truth. But most people would be amazed at the actual time verbose output can cost your program. Printing is very expensive, I remember when coding a big branch-and-bound project for the cap-mst problem in college, it was responsible for like 70-80% of the total running time, which was huge. And I just couldn't believe it. So I think most people (specially non-programmers) have no idea how expensive it can be, and I can tell you I rarely use -v, unless I need it.	[reply]

Since I run my own proxy at home, I can assume that most downloads live in the cache, so I just do: `curl <URL> \| tar -jx or wget -O - <URL> \| tar -jx` [download] most of the time. -nuffin zz zZ Z Z #!perl	[reply] [d/l]

Indeed. When the first Exabyte tape drives came out (like Hi-8 video tapes for those who don't remember,) it was recommended not to use `-v` on the particular platform I was using at the time because it caused some weird timing problem on the SCSI bus (probably due to a bug in the OS but that's another story.) /J\	[reply] [d/l]

Well, someone could consider the bible as the README (personally i don't). BTW, why 'she' (or why not...)?	[reply]

Then it must be the worst written README ever. READMEs ought to contain clear, unambigious instructions. In the bible, it isn't even clear what's an instruction and what's a fairy tale.

maybe it's more like a unix man page than a README. It contains clear instructions, but only if you already know what's in there. He who asks will be a fool for five minutes, but he who doesn't ask will remain a fool for life. Chady \| http://chady.net/ Are you a Linux user in Lebanon? join the Lebanese Linux User Group.

Though the Bible is my readme, I find it odd that you didn't think to meantion any of the other "holy" books: I Ching (Book of Change), Quran, Tora, the many writtening of the Zen Roshis (and yes I could keep adding to this list). Though I don't wish to open this topic to a broader discuss (that would be inappropriate for perlmonks), I did wish to meantion that others might think of a different "readme".

A README file is just an introduction to the system, it's a part of the system, in fact the most trivial part. If you're talking about a README for your life, then your birth certificate (or some similar tangible statement that "YOU ARE HERE ->(X)" is enough for a README isn't it?? The real trick is what happens when you use the system, run it thru the paces and realize how it works in ways that no one else even imagined, or suggested, or anticipated. Then do you not begin to see the "words" behind the readme, and the programming behind the code. There is no spoon.	[reply]
