# bootpef(8)

BOOTP Extension File compiler

## NAME

**bootpef** – BOOTP Extension File compiler

## SYNOPSIS

**bootpef** \[**-c** *chdir-path*\] \[**-d** *debug-level*\] \[**-f** *config-file*\] \[*client-name* *...*\]

## DESCRIPTION

The **bootpef** utility builds the *Extension Path* files described by (tag 18). If any *client-name* arguments are specified, then **bootpef** compiles the extension files for only those clients.

## OPTIONS

- **-c** *chdir-path*

  Sets the current directory used by **bootpef** while creating extension files. This is useful when the extension file names are specified as relative pathnames, and **bootpef** needs to use the same current directory as the TFTP server (typically */tftpboot*).

- **-d** *debug-level*

  Sets the *debug-level* variable that controls the amount of debugging messages generated. For example, **-d** *4* will set the debugging level to 4.

- **-f** *config-file*

  Set the name of the config file that specifies the option data to be sent to each client.
