How to get absolute value of integer? abs command does not work, man pages exist

Thanks [member=7701]kpanic[/member] , your solution worked well. Last night I did a clunkier workaround, where I tested if the number was less than zero, and if so, I subtracted the number from zero. But your solution with sed looks like it's a lot faster. It worked beautifully when I tested it today. Marking as solved.
