It shows what system calls a program is doing. Compile this simple hello
world program and run 'strace ./hello'. Then boggle at the number of
system calls required to print hello world on the screen.
cat > hello.c <<EOM
int main(void) {
printf("hello world\n");
exit (0);
}
EOM
cc -o hello hello.c
strace ./hello
also try
cc --static -o hello hello.c
strace ./hello
It's useful if you have a program that just prints an unhelpful error
message such as "Unable to open file." - simply run it through strace
and it should show something like:
open("/etc/thefile", O_RDONLY) = -1 ENOENT (No such file or directory)
Hey presto, That could well be the file you need to look at creating.

Headless Linux box sitting in the corner doing ipmasq/ipchains/various
services internally. putty to linux box from windows machine to read
email, mush, login to work etc.
When I used to use an X frontend (a good 2-3 years back), I had a very
cut-down fvwm(1&2) setup with minimal decoration and very little in the
way of extras. I've still got the config file - tried KDE and Gnome and
didn't like either of them. I never really tweaked the default config
though so maybe that's where I went wrong.
