  • Use aws cli exclusively to query useful information about instances in a VPC

    Following in the steps of a few other scripts on here, I thought I'd mix in the ability to add in an instance tag output into this. This can be super useful if you are using the "Name" tag as a hostname tag and feeding that into, say Route53 for DNS to reach the machine. Helps for scripting against later. Show Sample Output


    0
    aws ec2 describe-instances --filters "Name=vpc-id,Values=<replace_with_id>" --query 'Reservations[].Instances[].[ [Tags[?Key==`Name`].Value][0][0],PrivateIpAddress,InstanceId,State.Name,Placement.AvailabilityZone ]' --output table

Check if it's your binary birthday!
Print out your age in days in binary. Today's my binary birthday, I'm 2^14 days old :-) . This command does bash arithmatic $(( )) on two dates: Today: $(date +%s) Date of birth: $(date +%s -d YYYY-MM-DD) The dates are expressed as the number of seconds since the Unix epoch (Jan 1970), so we devide the difference by 86400 (seconds per day). . Finally we pipe "obase=2; DAYS-OLD" into bc to convert to binary. (obase == output base)

diff the same file in two directories.
This is useful when you're diffing two files of the same name in radically different directory trees. For example: Set $ path1='/some/long/convoluted/path/to/all/of/your/source/from/a/long/dead/machine' then $ path2='/local/version/of/same/file' then run the command. Much easier on the eyes when you're looking back across your command history, especially if you're doing the same diff over and over again.
