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

Yes, by correctly setting the HIST* variables you can make certain commands not saved in history. But that's complicated and easy to make a mistake. If you set HISTFILE= to blank, nothing in your current shell session will be saved in history. Although this is not a precise answer to the subject, but it's very simple.
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
Print the max wattage of the current power draw source for a Mac. Note that the current amount of watts drawn may be lower, particularly if a high-wattage adapter is plugged into a Mac that has a full battery.

options: -n line nbrs, -i ignore case, -s no "doesn't exist", -I ignore binary
args: * for all files of current dir (not hidden), .[!.]* for all hidden files
I don't include by default the -R (recursive) option, which is not always useful. You add it by hand when needed.
My variation on an audio burning command from commandlinefu - this one doesn't crap out if you want to burn a CD in a directory whose permissions don't allow it, and instead rips everything to /tmp. If you mount your music partition like I do using Samba, you probably don't have write permission inside that file system in order to create the temporary directory other audio burning commands here use. Not a bad idea to add cdrom to your groups, and /bin/eject with visudo.
