Advanced python tracing
Trace python statement execution and syscalls invoked during that simultaneously

list files recursively by size

Create passwords and store safely with gpg
Adjust the $ head -c part for password length. I use filenames like "hans@commandlinefu.com.gpg" and a vim which automatically decrypts files with .gpg suffixes.

Create a tar archive using xz compression
compress directory archive with xz compression, if tar doesn't have the -J option (OSX tar doesn't have -J)

ping a range of IP addresses
nmap accepts a wide variety of addressing notation, multiple targets/ranges, etc.

Download streaming video in mms
require mimms package

for ssh uptime
This will run them at the same time and timeout for each host in ten seconds. Also, mussh will append the ip addres to the beginning of the output so you know which host resonded with which time. The use of the sequence expression {1..50} is not specific to mussh. The `seq ...` works, but is less efficient.

Capitalize first letter of each word in a string
Ruby ftw

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
