I would like to make my dev sites have port numbers. I thought I would just start at a certain number and increment by 1 every new site. The question is what number should I start with? I have know there are reserved ports at various numbers. Are there a range of numbers that can be assumed safe to use?

This 'Count Numbers' free game teaches children to recognize and write numbers 1- 10, understand missing numbers, greater smaller, and more.

I need to format phone numbers in a text file. They appear as (example) 8014516912

How would I format it so that I can insert a - after the first 3 numbers, and then another - after another 3 numbers, so it would appear as 801-451-6912

How would I do this for all lines that contain a phone number?

I used to have root but not too long ago I flashed the stock tar to return to stock unrooted and when I try to update the new software it gives me an error. I tried to do the firmware upgrade and initialization thing from kies and when I entered the meid it keeps saying to reenter the information because it's invalid.

I'm using Excel 2010, and have a spreadsheet of simple numbers (they're 1-5 ratings for a range of questions), so I have questions across the top, and each person's responses as a separate row. The numbers are whole numbers, but each cell has an error checking marker saying 'Number Stored as Text'.

My search this morning was about how could I compare two decimal numbers in bash, and I came to this answser: How to compare to floating point number in a shell script.

Hello to all,

I have show below a file separated by commas. In first column has numbers where the last number is 13.

Code:
1,4
2,6
3,7
5,2
6,5
7,5
8,65
9,10
11,78
13,2
What I want to know is which numbers are missing from 1 to 13 (in this case 13 is last number in column 1).

I am able to drag and drop contacts into Numbers where it creates a table with all the information.

However, in the Address book several people have multiple 'work' phone numbers, or multiple 'emails'. This means that when the contact is dragged into Numbers, Numbers only recognises the first 'work' number, and doesn't include the second 'work number'.

I have a .txt file containing 4-digit numbers.

sometimes they only contain one 4-digit number, sometimes multiple 4-digit numbers, sometimes they are empty.

example1.txt file: 6304 6204

example2.txt file: 6308

What I need to do, is to check if the numbers inside the file are in a list of numbers I have in an other textfile.
