How do you c to call system comands like df on linux or ipconfig form a c
program?

Doesn't matter what OS you're using:

system( "df" );
system( "ifconfig" );

But I guess you don't actually want system() because you also want
to read what the command you invoked did return directly instead of
having to write it to a file first and then read in the file. In this
case the answer becomes system-dependent and thus off-topic here.
<OT>
But if you ask e.g. in comp.unix.programmer one of the answers you
will probably get is to use e.g. popen() and pclose() instead of
system() in this case.
