Hi, here's what I'm trying to do,
I used awk to separate numbers from a file into a list like this:
4536
23426
452
7647
35637
35635
35653
Now I need to randomly select one of this numbers, and make it a variable.
Any ideas on how to do this??
Thank you! (5 Replies)

I use %random to generate random number but i want to mod it so i get random number below 50 only in ksh script
how can i do it

doesn't work
help is appreciated.
Is there any other way i get generate random number below 50 in ksh.any other function.

Hi,
Could you please let me know what the following code does, I know that it means generating random numbers, however not sure what is the entire purpose.

Need to use dd to generate a large file from a sample file of random data. This is because I don't have /dev/urandom.
I create a named pipe then:
dd if=mynamed.fifo do=myfile.fifo bs=1024 count=1024
but when I cat a file to the fifo that's 1024 random bytes:

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.
