.SH "NAME"
ifdata \- get network interface info without parsing ifconfig output
.SH "SYNOPSIS"
.HP \w'\fBifdata\fR\ 'u
\fBifdata\fR [options] {\fIiface\fR}
.SH "DESCRIPTION"
.PP
\fBifdata\fR
can be used to check for the existence of a network interface, or to get information about the interface, such as its IP address\&. Unlike

\fBifdata\fR
has simple to parse output that is designed to be easily used by a shell script\&.
