Linux (as a whole incl. kernel and userland) can still surprise you even when you are already using it for several years. Todays lesson covers Debians coreutils package, specifically the "ln" command.
I just discovered that you can use "ln -s /path/to/something" in the working directory to create a symbolic link to "/path/to/something" in the current directory named "something" instead of needing to type the whole "ln -s /path/to/somethin /where/it/should/go/something"! Astounishing! Whoooaaa!
And yes, I'm using Linux/Unix for over a decade now and didn't know that. Alas, I've already told other Senior Sysadmins about the existance of the "screen" util and made them happy... ;-)
