10 - 3rd party linux tools

Package Managers​

NVM​

NVM is a way to manage different versions of node.

Installation​

You can install NVM through a curl command to the git repo. NVM also adds lines of code to the ~/.bashrc in order to source the NVM and run it upon startup.

Git Bash​

For git bash, you can install NVM as normal but then you must add the sourcing code to ~/.bash_profile as that is what is run at the start of every session instead of ~/.bashrc.

Usage​

You can install node with nvm install node or nvm install <version>.

You can use a specific version with nvm use <version>:

  • nvm install 20: installs node version 20
  • nvm install --lts: installs the current lts version of node

gog: manage google ecosystem​

Setup​

To use gog, you first need OAuth permissions. Follow these steps:

  1. Go to the Google Cloud Console (https://console.cloud.google.com/apis).
  2. Create or select a project.
  3. Create OAuth 2.0 credentials:
    • Go to "APIs & Services" > "Credentials."
    • Click "Create Credentials" > "OAuth Client ID."
    • Choose "Desktop App" or "Other" as the application type.

  1. Go Go to the individual Google Drive API and Google Docs API pages and enable those APIs. This is required for GOG to be able to use them with your OAuth client ID.
  2. Download the secret JSON after the client ID is successfully created: this is the credentials you use for permanent gog access. Then authenticate with it

Auth setup​

You can use gog to manage multiple google email workspaces at the same time. To do so, you must first login:

gog login <email>

You also have these tools to manage multiple auth accounts:

  • gog auth add <email>: adds the gmail account and authenticates with it
  • gog auth remove <email>: removes the gmail account from the authenticated accounts.
  • gog auth list: lists all the authenticated accounts with this CLI

Obsidian CLI​

The obsidian cli is run with the obsidian command which brings up a TUI (interactive CLI). The TUI and CLI are only available if the Obsidian app is currently open.

Vault Commands​

These commands run in the context of the current vault you have open in obsidian

  • daily: opens today's daily note in the current vault
  • daily:append: appends content to the daily note, and then you can pass in key=value arguments.
  • search: searches the current vault, and then you can pass in key=value arguments.
  • create: creates a new note, and then you can pass in key=value arguments.
# Open today's daily note
obsidian daily

# Add a task to your daily note
obsidian daily:append content="- [ ] Buy groceries"

# Search your vault
obsidian search query="meeting notes"

# Read the active file
obsidian read

# List all tasks from your daily note
obsidian tasks daily

# Create a new note from a template
obsidian create name="Trip to Paris" template=Travel

# Create a new note with content
obsidian create name=Note content="# Title\n\nBody text"

# List all tags in your vault with counts
obsidian tags counts

# Compare two versions of a file
obsidian diff file=README from=1 to=3

Switching vaults​

you can run vault commands in a different vault by specifying the vault name you want to target with the vault= command:

obsidian vault=Notes daily

Opening a vault​

Open a vault from the TUI with the vault:open command, passing the name of the vault:

vault:open name=<name>        # (required) vault name

ImageMagick​

You can install this CLI tool using brew on mac.

The basics of using it follow this pattern:

magick [input-options] input-file [output-options] output-file

Basics​

Here are the 9 most common use cases:

  1. Convert an image to a different format

To convert a JPEG to a PNG, simply specify the new file extension in the output file name. 

magick input.jpg output.png
  1. Resize an image

  • Resize to specific dimensions: To fit an image within a given width and height while maintaining its aspect ratio, use the -resize option.

    magick input.png -resize 800x600 output.png

  • Force specific dimensions: To stretch or shrink an image to an exact size, ignoring the aspect ratio, add an exclamation mark (!).

    magick input.png -resize 800x600! output.png

  • Resize by percentage: Use a percentage value to scale the image proportionally.

    magick input.png -resize 50% output.png

     

  1. Crop an image

Crop an image by specifying the width, height, and starting position (+x+y). The coordinates are from the top-left corner. 

magick input.png -crop 200x200+50+50 output.png
  1. Rotate and flip an image

  • Rotate: Rotate an image by a specified number of degrees.

    magick input.png -rotate 90 output.png

  • Flip (vertical): Flip the image along its horizontal axis.

    magick input.png -flip output.png

  • Flop (horizontal): Flip the image along its vertical axis.

    magick input.png -flop output.png

     

  1. Add text to an image

Use the -annotate and -draw options to add text. The example below adds "Hello World" at a specific location. 

magick input.png -pointsize 48 -fill white -annotate +20+50 "Hello World" output.png
  1. Add a watermark or composite images

The composite command overlays one image on another. 

composite watermark.png input.png output.png

You can also do this with magick, which can be more versatile for complex operations. 

magick input.png watermark.png -composite output.png
  1. Create a GIF animation

Combine a series of images into a single animated GIF. The -delay option sets the time between frames in hundredths of a second. 

magick -delay 20 -loop 0 image1.png image2.png image3.png animation.gif
  • -delay 20: 20 hundredths of a second (0.2 seconds) between frames.
  • -loop 0: Infinite loop. 
  1. Batch processing with mogrify

To apply the same change to many files at once, use mogrify. It directly modifies files, so it's a good idea to back up your images first. 

  • Resize all JPEGs in a directory:

    magick mogrify -resize 800x600 *.jpg

  • Convert all JPEGs to PNGs:

    magick mogrify -format png *.jpg
  1. Identify image information

Use the identify command to get detailed information about an image. 

magick identify -verbose input.png

Playing sounds​

Playing sounds on a mac

This is some built in code for zsh that allows us to play system sounds:

afplay /System/Library/Sounds/Glass.aiff

saying text

This is how to do robotic text to speech: use the say command

say 'process complete'

Apple CLI​

remindctl​

The remindctl tool is used to create apple reminders.

Dev tunnel utilities​

ngrok​

ngrok is a tool used to enable HTTPS in development by creating a temporary HTTPS url that forwards to your dev server. This is useful for stuff like registering webhooks.

To get a HTTPS dev url that forwards to a dev process you have running on a port, use this command:

ngrok http <port_number>

dev-tunnel​

The devtunnel CLI from microsoft allows you to authenticate with your microsoft account to set up devtunnels and can be easier than ngrok.

  1. Install the CLI
brew install --cask devtunnel host -p 3978
  1. Expose a port
devtunnel host -p 3978

You can also use these commands to manage your dev tunnels.

Commands:
  list                 List tunnels
  show <tunnel-id>     Show tunnel details
  create <tunnel-id>   Create a tunnel
  update <tunnel-id>   Update tunnel properties
  delete <tunnel-id>   Delete a tunnel
  delete-all           Delete all tunnels
  token <tunnel-id>    Issue tunnel access token
  set <tunnel-id>      Set default tunnel
  unset                Clear default tunnel
  access               Manage tunnel access control entries
  user                 Manage user credentials
  port                 Manage tunnel ports
  host <tunnel-id>     Host a tunnel, if tunnel ID is not specified a new 
                       tunnel will be created
  connect <tunnel-id>  Connect to an existing tunnel
  limits               List user limits
  clusters             List available service clusters by location
  echo <protocol>      Run a diagnostic echo server on a local port
  ping <uri>           Send diagnostic messages to a remote echo server
