Edit a file on a remote host using vim

Exclude grep from your grepped output of ps (alias included in description)
Surround the first letter of what you are grepping with square brackets and you won't have to spawn a second instance of grep -v. You could also use an alias like this (albeit with sed): alias psgrep='ps aux | grep $(echo $1 | sed "s/^\(.\)/[\1]/g")'

list all opened ports on host

list with full path

bash screensaver (scrolling ascii art with customizable message)
Displays a scrolling banner which loops until you hit Ctrl-C to terminate it. Make sure you finish your banner message with a space so it will loop nicely.

List docker volumes by container

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"

Remove several files with ease
Rather than typing out all 10 files, you can use brace expansion to do the trick for you. This is useful for backup files, numbered files, or any files with a repeating pattern. Gives more control than 'rm file*' as I might want to keep others around.

Get max number of arguments
Get max number of arguments that can be accepted by the exec() system call.

Show all programs on UDP and TCP ports with timer information
-p PID and name of the program -u on a UDP port. -t also TCP ports -o networking timer -n numeric IP addresses (don't resolve them) -a all sockets
