Lazy Linux: 10 Essential tricks for admins is an awesome list of cool things you can do with Linux. I learned about trick #3 (collaboration with screen) from an admin at the datacenter where one of my servers is hosted. I remember being thrilled sitting there watching him do stuff on my server while sharing the keyboard to type messages back and forth in vi (think Remote Desktop or VNC, but on the console). Trick #5 (SSH back door) is something I've been using for years at work for remote diagnostics. It is an invaluable trick for getting around firewalls. Very cool stuff!
- Being Greedy With Bash — Last night at my C/Unix class the professor quickly glossed over an interesting shell scripting technique that allows you to strip stuff off the beginning or end of a variable.
- I subconsciously converted a problem into a shell script — I have been writing a lot of shell scripts lately as part of the C/Unix class that I'm taking at Harvard Extension.
- HOWTO: Count Files Recursively with Exclusion on Linux — Find all files in this directory, including the files in sub-directories, and exclude all files that start with a period (dot files) and any directories named .thumbs.
- Mounting HFS+ with Write Access in Debian — When I decided to reformat and install my Mac Mini with the latest testing version of Debian (lenny, at the time of this writing) I discovered that I couldn't mount my HFS+ OS X backup drive with write access: erin:/# mount -t hfsplus /dev/sda /osx-backup [ 630.769804] hfs: write access to a journaled filesystem is not supported, use the force option at your own risk, mounting read-only.
- Understanding the Linux Load Averages — I have been using Linux for several years now and although I have looked at the load averages from time to time (either using top or uptime), I never really understood what they meant.
