Strip my code to:
wmctrl -o 0,0 # autorotates to the first face. In fact [0-1279],0
wmctrl - 1280,0 # goes to the second face
wmctrl -o 2560,0 # goes to the third face, and so on.
# Use multiples of the horizontal display resolution.
My example work for 1280x800 display, been 1280 the number of interest.
Tweak the number, try a biiiig one and see your cube spinning...
I put a complex example to show how fun things can be, even for my ademco and paradox alarm central network advisor interface xpto etc. It rotates two faces, print the alarm message, and goes back tho where it was.
Tested on BIGLINUX 4.2, equivalent to ubuntu LTS hardy.
Do not forget to activate 3D efects ( compiz cube )
Using perl and tput, show all the colors with numbers that your actual $TERM can handle.
If want to remove the numbers at beginning of new line, it should be something like this:

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
The pinfo package makes info pages much more bearable. It is a ncurses-based POSIX utility for viewing info and man pages using lynx style keyboard shortcuts and rendering. Links are highlighted blue, the current location of your cursor is red. Navigating and searching are easy. Worth the install.
You can view the man pages from section five by passing the section number as an argument to the man command
This is likely only valid on Solaris based systems. Unfortunately a lot of the more universal techniques for determining if a system is 32bit or 64bit on x86 solaris fail to give much more information than "i86pc"
When you press TAB twice in your prompt, bash tells you something like
"Display all 4567 possibilities? (y or n)"
But when you press "y" you only get the list in the terminal output and, if you want to save it to a file, you have to copy it by hand from the vterm screen. With this utility you save the list to a file or pipe it to another command at will
You can use the file saved list to grep for a particular pattern, useful if you are searching for a command but you only remember a few letters
