Check These Out

get a fresh commandlinefu-item each day as motd
Commandline-fu often has little tricks that I always forget. By adding this to the root-cron (sudo crontab -e) I lean a new trick every day.

Numerically sorted human readable disk usage
Provides numerically sorted human readable du output. I so wish there was just a du flag for this.

attach to bash shell in the last container you started

Clear current session history (bash)

List your MACs address
The output of ifconfig is localized, using it will fail in non-English environment. "ip" command in iproute2 provides a consistent output and thus is more robust

Copy a directory recursively without data/files

Get absolut path to your bash-script
Another way of doing it that's a bit clearer. I'm a fan of readable code.

Show simple disk IO table using snmp
Show a simple table with disk IO for the specified host. you monitor a LOT of different thing. Mostly used for MRTG and similar, but this is nice for a quick look, which disk is busy. "public" is your SNMP community ensure that snmpd is running on the host which you intend to monitor

Place the NUM-th argument of the most recent command on the shell
After executing a command with multiple arguments like cp ./temp/test.sh ~/prog/ifdown.sh you can paste any argument of the previous command to the console, like ls -l ALT+1+. is equivalent to ls -l ./temp/test.sh ALT+0+. stands for command itself ('ls' in this case) Simple ALT+. cycles through last arguments of previous commands.

list block devices
Shows all block devices in a tree with descruptions of what they are.
