Get AWS temporary credentials ready to export based on a MFA virtual appliance
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

Use this command if you want your terminal commands be saved in your history file in real time instead of waiting until the terminal is closed

execute your commands hiding secret bits from history records
$ wget --user=username --password="$password" http://example.org/ Instead of hiding commands entirely from history, I prefer to use "read" to put the password into a variable, and then use that variable in the commands instead of the password. Without the "-e" and "-s" it should work in any bourne-type shell, but the -s is what makes sure the password doesn't get echoed to the screen at all. (-e makes editing work a bit better)

ncdu - ncurses disk usage
ncdu is a text-mode ncurses-based disk usage analyzer. Useful for when you want to see where all your space is going. For a single flat directory it isn't more elaborate than an du|sort or some such thing, but this analyzes all directories below the one you specify so space consumed by files inside subdirectories is taken into account. This way you get the full picture. Features: file deletion, file size or size on disk and refresh as contents change. Homepage: http://dev.yorhel.nl/ncdu

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"
