Check These Out

list all files in a directory, sorted in reverse order by modification time, use file descriptors.
It's both silly, and infinitely useful. Especially useful in logfile directories where you want to know what file is being updated while troubleshooting.

Rename files in batch

List all PostgreSQL databases. Useful when doing backups

Create a mirror of a local folder, on a remote server
Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)

continuously check size of files or directories
very handy if you copy or download a/some file(s) and want to know how big it is at the moment

generate 30 x 30 matrix
Replaces hexdump with the more succint xxd, and the sed was unnecessarily complex.

Detect illegal access to kernel space, potentially useful for Meltdown detection
Based on capsule8 agent examples, not rigorously tested

Recursively find top 20 largest files (> 1MB) sort human readable format
from my bashrc ;)

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"

open path with your default GNOME program
Another step to bring cli and gui closer together: gnome-open It opens a path with the default (gui) application for its mime type. I would recommend a shorter alias like alias o=gnome-open More examples: $ gnome-open . [opens the current folder in nautilus / your default file browser] $ gnome-open some.pdf [opens some.pdf in evince / your default pdf viewer] $ gnome-open trash:// [opens the trash with nautilus] $ gnome-open http://www.commandlinefu.com [opens commandlinefu in your default webbrowser]
