FACTOR(1) General Commands Manual FACTOR(1)NAME
factor, primes - factor a number, generate large primes
SYNOPSIS
factor [ number ]
primes [ start [ finish ] ]
DESCRIPTION
Factor prints number and its prime factors, each repeated the proper number of times. The number must be positive and less than 2**56
(about 7.2e16)
If no number is given, factor reads a stream of numbers from the standard input and factors them. It exits on any input not a positive
integer. Maximum running time is proportional to sqrt(n).
Primes prints the prime numbers ranging from start to finish, where start and finish are positive numbers less than 2**56. If finish is
missing, primes prints without end; if start is missing, it reads the starting number from the standard input.

factor - obtain the prime factors of a number
SYNOPSIS
factor [integer]
DESCRIPTION
factor writes to standard input all prime factors for any positive integer less than or equal to 10^14. The prime factors are written the
proper number of times.
If factor is used without an argument, it waits for an integer to be entered. After entry of the integer, it factors it, writes its prime
factors the proper number of times, and then waits for another integer. factor exits if a 0 or any non-numeric character is entered.
If factor is invoked with an argument (integer), it writes the integer, factors it and writes all the prime factors as described above, and
then exits. If the argument is 0 or non-numeric, factor writes a 0 and then exits.
The maximum time to factor an integer is proportional to sqrt(n), where n is the integer which is entered. factor will take this time when
n is prime or the square of a prime.
OPERANDS
integer Any positive integer less than or equal to 10^14.
EXIT STATUS
0 Successful completion.
1 An error occurred.
DIAGNOSTICS
factor prints the error message Ouch! for input out of range or for garbage input.

Hi all,
I have been working with java for awhile and because of my school projects I needed to switch C++. I tried to implement some patterns in C++ but unfortunately I couldn't. Specifically, I tried to implement abstract factory pattern but since I used separated files (habitual behavior from... (4 Replies)
Can someone please help me with this SHELL script?
I need to create a script that gets a positive number n as an argument. The script must calculate the factorial of its argument. In other words, it must calculate n!=1x2x3x...xn. Note that 0!=1.
Here is a start but I have no clue how to... (3 Replies)
Hi,
I am trying to run the factorial script but it’s not working.

I am completely new to Shell scripting and I have almost no idea what I'm doing here. I'm not a stranger at all to programming, but the way SHELL is done drives me to insanity. Here's my current issue:

This program takes in two (or three)... (6 Replies)
Hey guyz,
I have a table like this:
1 A=#;B=#;C=#
2 A=#;C=#;D=#;E=#;E=#
3 B=#;B=#;B=#;D=#
# are just some numbers. I want to have the output like this:
* 1 2 3
A # # NA
B # NA #
C # # NA
D NA # #
E NA # NA
So basically, I wanna know in each of the rows in my input (which... (9 Replies)
Hi all,
While doing some checks I found a kind of interesting arithmetic factorial chart with sed, sharing this may be simple but thought to share,
# n=20;for i in `seq $n`;do printf "`seq $i|xargs|sed 's/ /*/g'`= ";echo "`seq $i|xargs|sed 's/ /*/g'`"| bc;done
1= 1

Is anyone here familiar with implementing multi-factor authentication on HP-UX 11.31? Either with a PIV card, or with an RSA token? We've been tasked with implementing this on our servers, but I'm not finding much in the way of products or information. To complicate matters, our servers are... (6 Replies)
I have a factor program that runs and outputs to stdout all the prime numbers that are specified in the given paramters, in this case 30000000-31000000.
Command:
factor/factor 30000000-31000000
Sample output:
30999979 = 30999979
30999980 = 2^2 5 11 140909

Which basically means the ldoms that were on there are not starting (not even showing).
If I do ldm list-config it shows live config as next reboot. But, of course, next reboot it reverts back to factory default again.
I must admit I'm wondering if its doing this becasue (with the... (3 Replies)
Dear All,
I have Google Two Factor (2F) Authentication enabled for sshd on most of my Linux servers. This works well and I highly recommend it.
My question is:
Has anyone set this up for rsync which runs in a crontab?
For example, supposed we have this simple crontab script:
