Substitute feh for the image viewer of your choice. display (part of imagemagick) seems to be a popular choice.

Recursively unrar into dir containing archive
From the cwd, recursively find all rar files, extracting each rar into the directory where it was found, rather than cwd. A nice time saver if you've used wget or similar to mirror something, where each sub dir contains an rar archive. Its likely this can be tuned to work with multi-part archives where all parts use ambiguous .rar extensions but I didn't test this. Perhaps unrar would handle this gracefully anyway?

Sum size of files returned from FIND

Happy Days
AFAIR this is the wording ;)

Remove all the files except abc in the directory
Finds all files in the current directory and deletes them besides file called "abc"

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
