It has an enhanced SFTP file browser, SSH terminal emulator, remote resource/process manager, server disk space analyzer, remote text editor, huge remote log viewer, and lots of other helpful tools, which makes it easy to work with remote servers. Muon provides functionality similar to web-based control panels but, it works over SSH from the local computer, hence no installation is required on the server. It runs on Linux and Windows. Muon has been tested with several Linux and UNIX servers, like Ubuntu server, CentOS, RHEL, OpenSUSE, FreeBSD, OpenBSD, NetBSD, and HP-UX. The application is targeted mainly towards web/backend developers who often deploy/debug their code on remote servers and not overly fond of complex terminal-based commands. -

googler
Google from the terminal
googler is a power tool to Google (web, news, videos and site search) from the command line. It shows the title, URL and abstract for each result, which can be directly opened in a browser from the terminal. Results are fetched in pages (with page navigation). Supports sequential searches in a single googler instance. googler was initially written to cater to headless servers without X. You can integrate it with a text-based browser. However, it has grown into a very handy and flexible utility that delivers much more. For example, fetch any number of results or start anywhere, limit the search by any duration, define aliases to google search any number of websites, and switch domains easily, all of this in a very clean interface without ads or stray URLs. The shell completion scripts make sure you don't need to remember any options. -

qrcp
Transfer files over wifi from your computer to your mobile device
qrcp binds a web server to the address of your Wi-Fi network interface on a random port and creates a handler for it. The default handler serves the content and exits the program when the transfer is complete. When used to receive files, qrcp serves an upload page and handles the transfer. Most QR apps can detect URLs in decoded text and act accordingly (i.e. open the decoded URL with the default browser), so when the QR code is scanned the content will begin downloading by the mobile browser. When sending multiple files at once, qrcp creates a zip archive of the files or folders you want to transfer, and deletes the zip archive once the transfer is complete. When receiving files, qrcp serves an “upload page” through which you can choose files from your mobile. The default configuration file is stored in $HOME/qrcp.json, however, you can specify the location of the config file by passing the --config flag. -

aws-nuke
Nuke a whole AWS account and delete all its resources
Remove all resources from an AWS account. Be aware that aws-nuke is a very destructive tool, hence you have to be very careful while using it. Otherwise, you might delete production data. We strongly advise you to not run this application on any AWS account, where you cannot afford to lose all resources. We are testing our Terraform code with Jenkins. Sometimes a Terraform run fails during development and messes up the account. With aws-nuke, we can simply clean up the failed account so it can be reused for the next build. Our platform developers have their own AWS accounts where they can create their own Kubernetes clusters for testing purposes. With AWS-nuke it is very easy to clean up these accounts at the end of the day and keep the costs low. There are two ways to authenticate aws-nuke. There are static credentials and profiles. The later one can be configured in the shared credentials file. -
