showdhc - Displays the contents of DHCP client configuration files
The showdhc command reads the files specified on the command line and, assuming they are configuration files, displays the data contained in them. The format of the output is a single line as shown in the Format section of the bootptab(4) reference page.
If any of the files named on the command line is not of the correct type, diagnostic output is sent to stderr. Configuration files are identified by an internal magic number, and the major and minor release numbers of JOIN configuration files are usually written to the /etc/join directory and are named interface.dhc.
