list files recursively by size

List bash functions defined in .bash_profile or .bashrc
typeset command gives to stdout all the functions defined in a bash session, -f and -F switches are for: all functions names with body (-f) and all functions names only (-F).

Find directories over 50MB in the home directory

Advanced ls using find to show much more detail than ls ever could
This alias is super-handy for me because it quickly shows the details of each file in the current directory. The output is nice because it is sortable, allowing you to expand this basic example to do something amazing like showing you a list of the newest files, the largest files, files with bad perms, etc.. A recursive alias would be: $ alias LSR='find -mount -printf "%.5m %10M %#9u:%-9g %#5U:%-5G %TF_%TR %CF_%CR %AF_%AR %#15s [%Y] %p\n" 2>/dev/null' From: http://www.askapache.com/linux/bash_profile-functions-advanced-shell.html

Better than: $ nodetool clearsnapshot

watch iptables counters
This will allow you to watch as matches occur in real-time. To filter out only ACCEPT, DROP, LOG..etc, then run the following command: watch 'iptables -nvL | grep -v "0 0" && grep "ACCEPT"' The -v is used to do an inverted filter. ie. NOT "0 0"

Concatenate (join) video files
Use mencoder to concatenate (join) multiple video files together.

Follow the most recently updated log files
This command finds the 5 (-n5) most frequently updated logs in /var/log, and then does a multifile tail follow of those log files. Alternately, you can do this to follow a specific list of log files: sudo tail -n0 -f /var/log/{messages,secure,cron,cups/error_log}
