Show GCC-generated optimization commands when using the "-march=native" or "-mtune=native" switches for compilation.
You can tell GCC to automatically select optimization commands and produce optimized code for the local machine (the one compiling the code), but you can't normally see what switches have been selected and used unless you append a "-v" and pause compilation.

Make the "tree" command pretty and useful by default
I got really tired of having tree always show me tons of .svn and .git stuff that I don't care about. With this alias, "tree" uses pretty colors, snazzy line graphics, and ignores any source control and package mumbojumbo. (Customize the *.*.package glob, of course.)

-s must be a valid resolution. You can get a list of valid (and supported) resolutions via `xrandr`.

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
