Hi,
Say there is a web page that contains just text only - that is, even the source code is just the text itself, nothing more. An example would be "http://mynasadata.larc.nasa.gov/docs/ocean_percent.txt"

First, let me state that I am completely out of my realm with this.
I have a server running HPUX. I'm not even sure if this can be considered a UNIX question and for that let me apologize in advance.

Hello,
Does anyone know of a way to list all files related to a single web page and then to download say 4 files at a time simultaneously until the entire web page has been downloaded successfully? I'm essentially trying to mimic a browser.
Thanks. (2 Replies)

random
RANDOM(4) BSD Kernel Interfaces Manual RANDOM(4)NAME
random , urandom -- random data source devices.
SYNOPSIS
pseudo-device random
DESCRIPTION
The random device produces uniformly distributed random byte values of potentially high quality.
To obtain random bytes, open /dev/random for reading and read from it.
The same random data is also available from getentropy(2). Using the getentropy(2) system call interface will provide resiliency to file
descriptor exhaustion, chroot, or sandboxing which can make /dev/random unavailable. Additionally, the arc4random(3) API provides a fast
userspace random number generator built on the random data source and is preferred over directly accessing the system's random device.
/dev/urandom is a compatibility nod to Linux. On Linux, /dev/urandom will produce lower quality output if the entropy pool drains, while
/dev/random will prefer to block and wait for additional entropy to be collected. With Yarrow, this choice and distinction is not necessary,
and the two devices behave identically. You may use either.
The random device implements the Yarrow pseudo random number generator algorithm and maintains its entropy pool. The kernel automatically
seeds the algorithm with additional entropy during normal execution.
