Create a new file

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

ping as traceroute
This command uses ping to get the routers' IP addresses to the destination host as traceroute does. If you know what I mean..

Install pip with Proxy
Installs pip packages defining a proxy

Get ElasticSearch configuration and version details
Replace localhost:9200 with your server location and port. This is the ElasticSearch's default setup for local instances.

identify NEEDED sonames in a path
This works in combination with http://www.commandlinefu.com/commands/view/10496/identify-exported-sonames-in-a-path as it reports the NEEDED entries present in the files within a given path. You can then compare it with the libraries that are exported to make sure that, when cross-building a firmware image, you're not bringing in dependencies from the build host. The short version of it as can be seen in the same output is $ scanelf -RBnq -F "+n#f" $1 | tr ',' '\n' | sort -u

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"

Find files of two different extensions and copy them to a directory

Remove a range of lines from a file
Deletes lines from START to END, inclusive. For example +4,10d will delete line 4, 5, ..., 10. Just like the vi command :4,10d does it.

Load another file in vim
You can then switch from a file to another with ^W^W
