Hello,

I have some extra time at work and I'm trying to come up with a good prime number generator for very large numbers that can take advantage of multiple (hundreds) cores. I realize Perl may...

This code works fine for me.

if [ $? == 0 ]
then
echo "hello"
else
echo "goobye"
fi

I would if I knew how :confused:

This may be a dumb question, but how do I get the list in an array?

Thanks.

Thanks! Will this only select one of the numbers from the list?

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...

Thanks! I didn't realize people were finding these numbers on personal computers, I guess I may make the leader board considering each core has 4 GB of memory :)

Hi,

I was just wondering if anyone has, or knows where to download a prime number finder program. I would like a fairly simple bash program, and also I would like one that could take advantage of...

Thanks! It seems to be working fine.

Thanks for looking into it Klashxx,

When I try your suggestion, and say I input these numbers:

255 256 280 290

I get this error:

awk: cmd. line:6: fatal: cannot open file `255' for...

Thanks again for your help drl, but I apparently don't have the wdiff command available to me. Any other ideas? Thanks!

Thanks for the help, but this doesn't work quite right either.

If for example, I enter the following:

Input1: 1 2 6 4 70
Input2: 1 6 2 4 80 90 670

I get the following response:

Nodes...

rubin,

Thanks a lot for looking into it! It works perfectly for the example I gave, however if I enter something like this:

input1= 1 2 3 4 5 80 90

input2= 1 2 3 4 5 6 80 90


I get this...

I would like my script to be able to tell the difference between to lines of input, like:

Input 1:
1 2 3 4 5
Input 2:
1 2 3 4 5 6

I want the script to tell me that the difference between the...

Wow drl, that's really cool. It works just as I need it to! I'll definitely delve deeper into those commands so I can understand them better. Thanks so much for your help!

drl,

Are you saying I need to get each of the numbers into a separate line?

I really don't know how I would go about it doing it manually.

I'm sorry, I didn't mean to have those comma's in there. Even with no comma's in the line, it still doesn't sort.

I guess I need...

Awesome! Thanks drl, it worked perfectly.

Hopefully I only have one more question now.

I do what you suggested, and I want to sort the output of "eval echo" numerically, so I do this:
...

Okay, now I'm having another problem with my script.

If I type:

echo {12..18}

It will spit out:

12 13 14 15 16 17 18

However, my script looks like this:

echo "Input first set of...

Thank you drl and everyone else for your help, it worked great!

Thanks again!

KevinADC,

Thanks for looking into it. I tried it and got this error:

sed: -e expression #1, char 32: invalid reference \2 on `s' command's RHS


Is there anymore info I can give you to make...

Hi,

Here's what I'm trying to do. I have a set of numbers like this:

12-13 15-18 23-28 36-38 42-43 53-56 70-72 76 80-86 93-110 119-128

But I want to echo the ranges of numbers. Is there any...

OK, thanks. So how exactly would I fix this script? This script is used for finding and entering the directory that the .parentlock file is located for firefox.

#!/bin/bash

direc=$(find -name...

Hi,

I'm having problems with the "cd" command in bash not changing directories. From what I've read, I've gathered that scripts are child processes and can't change the directory of their parent...

You're right, I named the script "while" https://www.unix.com/images/smilies/tongue.gif

Thanks for your help!

Thanks. I was wondering if it was something like that. I was sure I had used that same syntax before and it worked.

Thanks again.
