  • 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 These Out

remove newlines from specific lines in a file using sed

Show running services (using systemctl)

Run a command as root, with a delay
$ sleep 1h ; sudo command or $ sudo sleep 1h ; sudo command won't work, because by the time the delay is up, sudo will want your password again.

Alternative for basename using grep to extract file name
Here's a bash version.

list all file extensions in a directory
Works on current directory, with built-in sorting.

check open ports without netstat or lsof

Recursively create a TAGS file for an entire source tree. TAGS files are useful for editors like Vim and Emacs

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Eliminate dead symlinks interactively in /usr/ recursevely
Its not mine... I get from textlive migration in gentoo : http://www.gentoo.org/proj/en/tex/texlive-migration-guide.xml
