Echo the contents of a Url
Directly send the content of a url to standard out. This command is most convenient for sending the output of a download directly to another command.

Output requirements.txt packages pinned to latest version
Given a requirements.txt file with unpinned package names, output the packages pinned to the latest version. Handy to copy/paste back into your requirements.txt when you start a new project. Note that this will download packages but not install them.

Print summary of referers with X amount of occurances
This prints a summary of your referers from your logs as long as they occurred a certain number of times (in this case 500). The grep command excludes the terms, I add this in to remove results Im not interested in.

check open ports without netstat or lsof

Quickly create an alias for changing into the current directory

list human readable files
