# \_\_numset(8)

deals with number-sets This program is part of afbackup

## NAME

**\_\_numset - deals with number-sets**\
 **This program is part of afbackup**

## SYNOPSIS

**\_\_numset \<set-1-specifier\> { + \| - \| in} \<set-2-specifier\>**

## DESCRIPTION

**This Program deals with set of numbers and can either remove elements of one set that exists in another set, or merge two sets.**

**If the second argument is a +, then the two sets are merged.**  **If the second argument is -, the elements in set2 are removed from set1.**

**If the second argument is the word "in", then it is tested, whether elements of set 1 are also contained in set 2.**

**The number of common elements will be the result in that case.**

**If the first argument is the character # (must be escaped in shell scripts, e.g. write '#'), the result is the number of elements in the set given as second argument.**  **Number set specifiers should not contain whitespace and may consist of numbers, commas and dashes.**

## EXAMPLES

**prompt# \_\_numset 1-3,5-9,14 - 5-13**

-

-

  **1-3,14**

**prompt# \_\_numset 3 - ""**

-
