Copy directories on FreeBSD!

Having no idea abt how to copy the folders!?

Try below:


cp -iprv /source /dist

i -> Interactive. Will prompt you if overwriting files.
p -> Preserve file attributes like date, time, etc.
r -> Recursive. Will also copy subdirectories.
v -> Verbose. Will show each file as it is copied.

Solution to Failure in Building a FreeBSD Custom Kernel!

So at that day I failed in building the kernel. After consulting the FreeBSD handbook, I got the solution. Here is simply the note:

1. Since I could not boot from my new kernel, the computer failed recognizing my boot devices.

2. Reboot the computer! Choose " Escape to a loader prompt from the system boot menu.

3. Type "unload kernel" to unload the bad kernel.

4. After that, continue on typing "boot /boot/kernel.old/kernel". The directory locates the last time "ok" booted kernel.

5. Successfully booted! Then go checking what's wrong and keep building & compiling a new kernel!

That's all for the solution!
