I also renamed 'class' to prefix since you can do things like 'kenv -p kern -s' to get interesting output like: el="kernel" el_options="" elname="/boot/kernel/kernel" :-P One thing to note is that 'kenv -p foo' is basically the same as 'kenv | grep ^foo', and that 'kenv -p foo -s' is basically the same as 'kenv | sed -ne '/^foo/{s///;p;}'. Generally new options aren't added to programs if they can be easily duplicated via a simple pipeline. Is there a reason that you need kenv to do this explicitly rather than using sed or grep? -- John Baldwin <jhb_at_FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.orgReceived on Mon May 03 2004 - 09:59:24 UTC
