  • jq is amazing for manipulating json on the commandline, but the developers have some weird ideas about how to handle shell redirections. This command works around them. Further reading:

    diff <(jq . -M -S < old.json) <(jq . -M -S < new.json)

  • Use the AWS CLI tools to generate a list instances, then pipe them to JQ to show only their launch time and instance id. Finally use sort to bring them out in runtime order. Find all those instances you launched months ago and have forgotten about. Show Sample Output

    aws ec2 describe-instances | jq '.["Reservations"]|.[]|.Instances|.[]|.LaunchTime + " " + .InstanceId' | sort -n

  • Frustrated with the manual domain migration process AWS has, I unsuccessfully tried to install cli53, route53-transfer. I instead wrote this oneliner to ease the export (which is not supported via the AWS console ATM). The output can be easily pasted into the "Import Hosted Zone" dialog in Route53. SOA/NS records are excluded since they cannot be automatically imported. Show Sample Output

    echo -e "\$ORIGIN\\n\$TTL\t1h\n" && aws route53 list-resource-record-sets --hosted-zone-id Z1EEXAMPLE9SF3 | jq -r '.ResourceRecordSets[] | [.Name, .Type, .ResourceRecords[0].Value] | join("\t")' - | grep -vE "NS|SOA"

  • Compactly display a bitcoin-cli fee estimate in satoshis/Byte, sat/B, date time stamp. Change the 6 to the desired number of confirmations. Display in btc/KB unit of measure: printf %g "$(bccli estimatesmartfee 6 "ECONOMICAL" | jq .feerate)";printf " btc/KB estimated feerate for 6 confirmations\nMultiply by 100,000 to get sat/B\n"; Two settings for estimate mode are "ECONOMICAL". "CONSERVATIVE" is the same as "UNSET" # jq is a json filter. sudo apt-get install jq Show Sample Output

    printf %g "$(bitcoin-cli estimatesmartfee 6 "ECONOMICAL" | jq .feerate*100000)";printf " sat/B estimated feerate for 6 confirmations as of $(date +%c)\nDivide by 100,000 to get btc/KB\n"

  • The only pre-requisite is jq (and curl, obviously). The other version used grep, but jq is much more suited to JSON parsing than that. Show Sample Output

    btc() { echo "1 BTC = $(curl -s$1.json | jq .bpi.\"$1\".rate | tr -d \"\"\") $1"; }

Simple way to envoke a secure vnc session through ssh enabled router.
The ip address is of the remote machine running the vncserver. Must log in first to the router then the VNC session. Very nice if you have open-wrt or dd-wrt on your router.

list block devices
Shows all block devices in a tree with descruptions of what they are.

Run a file system check on your next boot.
The empty file /forcefsck causes the file system check fsck to be run next time you boot up, after which it will be removed. This works too: $sudo >/forcefsck

Create higher quality gif from videos
I had to compress it a bit to meet the 255 limit. See sample for full command (274) usage: ffgif foo.ext Supports 3 arguments (optional) ffgif filename seek_time time_duration scale ffgif foo 10 5 320 will seek 10 seconds in, convert for 5 seconds at a 320 scale. Default will convert whole video to gif at 320 scale. Inspiration -
