How do I match two numbers, each preceded by dollar signs and with a hyphen between them, such as '$1,000 - $2,000'. I'd like to get the full range with the dollar signs included.

'$1,000 - $2,000'

Other examples:

'$30 - $40'

'$1-$2'

I've tried: ([\$0-9, -]*){1} It doesn't work when there are characters before.

    You can match `$1,000 - $2,000` in the string `$1,000 - $2,000` using the regular expression `.*`. To get a good answer to a regular expression question, you need to be a lot clearer about 1) what kinds of variable things you want to match, 2) what kinds of things look similar that you *don't* want to match, and 3) what the input looks like that contains the things from 1) and 2) – Gareth Aug 10 '15 at 23:28
  • For the actual pattern '$1,000 - $2,000' or for anything in that range with a dollar sign and a comma for thousands? – isosceleswheel Aug 10 '15 at 23:39
  • what about decimals `.`, two digits or no `.`? what about leading zeros? Is the `,` optional or do you have to build groups of 3 digits? Is the amount of spaces between the hypen optional? Is the `$` mandatory? Is there an upper bound? Do you also accept negative amounts? – maraca Aug 10 '15 at 23:53

\$1[0-9][0-9][1-9]\s

That seems simple to me...if you are excluding 1000 and 2000...if this is including 1000 and 2000 then 

\$((1[0-9][0-9][0-9])|(2000))\s

There is surely a cleaner way to do it...but this will do the job

**********************edit*************************

Now that you changed your question... I think a simple regex would be 

\$[0-9]*\s?\-\s?\$[0-9]*\s?

Dollar sign followed by any amount of numbers,

optional white space,

dash,

optional white space,

dollar sign followed by any numbers,

optional white space.

    you could remove the braces around 2000 and the other numbers and you could write [0-9]{3} but whether this is cleaner or not is probably a matter of taste. – maraca Aug 10 '15 at 23:41

To match '$1,000 - $2,000', you just use '$1,000 - $2,000' as the regular expression. To match anything in the range 1000 - 2000 with the format $x,xxx, use the regex:

'\$1,\d{3}|\$2,000'

To match any range between with 1000 as lower bound and 2000 as upper bound with the format $x,xxx - $x,xxx, use the regex:

'\$1,\d{3}|\$2,000 - \$1,\d{3}|\$2,000'
