comment How does reverse SSH tunneling work?
Hey, Erik, I was just about to start recycling your images for a presentation I'm preparing, but ... something about your -R option seems wrong. [-R [bind_address:]port:host:hostport] is what's on the openssh man page. To create what's in your drawing, wouldn't you need -R remotehost:456:nearhost:123 ? In fact, your -L options look as if they're reversed as well (man page says -L [bind_address:]port:host:hostport). Am I missing something?

The usual command to elevate your privilege level is sudo. You might alternately have to use su. There are man pages available for both commands.

Sure it's a regular expression. It matches db/migrate///////crea. :-)

comment How do I use the “if” command for multiple conditions?
This isn't portable and isn't a bash answer. stat works differently on different platforms. The -t option does something completely different in FreeBSD and OSX than it does in Linux.

comment How to find a Linux kernel that works ok on my PC?
I disagree. Older versions of distros will have unpatched, buggy and insecure software included. When improvements are made to an OS, it is very rare that support for older hardware is removed.
