# ifindex(8)

Create nodelist index

## NAME

**ifindex** - Create nodelist index

## SYNOPSIS

**ifindex** \[**-h**\] \[**-x** *verbosity*\] \[**-I** *file*\]

## DESCRIPTION

*Ifindex* creates a nodelist index which is used by ifcico for faster nodelist lookups.

Depending on the OPTIONS set when compiling the program, one of 3 different nodelist indices will be generated: a *db-* a *(g)dbm-* or a *dbz-* version. The *dbz-* type nodelist-index has some advantages (smaller indices and faster index generation) over the other 2 types but is currently only in **PRE-ALPHA** state - you should also read the README before using this type of nodelist-index.

## OPTIONS

- **-h**

  Display a short help message.

- **-x Verbosity**

  Set the debug verbosity. **Verbosity** may be a number from 0 to 32 to set 'on' bits from 1 to number, or a string of letters where 'a' = bit 1, 'b' = bit 2, etc. up to bit 26.

- **-I File**

  Use the alternate configuration file **File.**

## RETURN CODES

| --- | --- |
| 0 | Successfull |
| 64 | command line usage error |
| 65 | error reading config file |
