comment How to trigger a system self destruct with a certain password is entered
If it's the NSA you're worried about then dd if=/dev/urandom of=/dev/$HOME isn't going to do much good. Even assuming they're stupid enough to use the operating system instead of removing the disk and reading it directly, there are forensic recovery companies that can get data from a disk that's been overwritten and physically burned.

comment Triple compression and I only save 1% in space?
Every time I've used xs it's given a lot better compression, but a lot slower to compress. For example 50% to 25% but 20 seconds to 4 minutes (on text).

comment What happens when you delete a hard link?
The key is that creating the text file also adds a hard link. In *NIX filesystems, all files (inodes) must be hardlinked at least once into the directory structure.

comment What happens when you delete a hard link?
@cjm Opening a file adds a new hardlink in /proc. The same logic then appiles.

comment How can I get a static C compiler?
@Gilles The best way to get a C compiler as a standalone binary is to build it from source using a complier you already have.

And on an HPUX box it's /opt/ansic/bin/cc.

comment Why can't I run this C program?
Just checked a couple of Solaris boxes, and /usr/bin/cc links to /opt/SUNWspro/bin/cc on one and /opt/sunstudio12.1/bin/cc on the other. Regardless, it's still a C compiler.

comment Why can't I run this C program?
@BruceEdiger learning how fork() works includes learning that it can copy buffered output. Being a reasonably complicated system call, some confusion is probably necessary in the learning process.
