Weather Forecast [Terminal || Linux]

[thumbtak]

I found a cool weather forecast command for the Linux terminal.

Command:
$ curl wttr.in/[city]

Example:
$ curl wttr.in/new_york

How to add this as a panel shortcut, to quickly check the weather.

You’re encountering a common issue where a command works perfectly in a regular terminal session but fails when executed from a panel launcher. This often boils down to environment variables or path issues. Here’s a systematic approach to troubleshoot:

1. Verify the Full Path to kitty (or your terminal emulator of choice) and curl:

• Full Path to kitty:
  • Open a terminal and type which kitty.
  • Copy the output (e.g., /usr/bin/kitty).
  • In your launcher’s “Command” field, replace kitty with the full path.
• Full Path to curl:
  • Do the same for curl: which curl.
  • Substitute the full path in your launcher’s command.
• Example:
  • If kitty is at /usr/bin/kitty and curl is at /usr/bin/curl, your launcher command would be:
  • /usr/bin/kitty -e "/usr/bin/curl wttr.in/New_York"

2. Check Environment Variables:

• Launcher Environment:
  • Panel launchers might not inherit the same environment variables as a regular terminal session.
  • To test this, modify your script to output the PATH variable:
    • Create a script called weather.sh in your ~/Documents/Scripts directory (or any directory you like), and place this in it.

      Bash
      #!/bin/bash
      echo "PATH: $PATH"
      /usr/bin/curl wttr.in/New_York

  • Then create a launcher command to: /usr/bin/kitty -e "~/Documents/Scripts/weather.sh"
  • When you run the launcher, check the output in the kitty terminal. If the PATH is different from your regular terminal, that’s the problem.

Fixing PATH:

• • If the PATH is the issue, you can either:
    • Add the necessary directories to the PATH within your script.
    • Modify your system’s environment variables to ensure they are set for all applications.

3. Permissions:

• Ensure that the kitty and curl executables have the correct permissions. They should be executable.
• Verify that your home directory and any scripts you are running also have the correct permissions.

4. Simple Test:

• As a simple test to isolate the curl command, try this command in your launcher:
  • /usr/bin/kitty -e "echo test"
• If that does not work, then there is a core issue with how kitty is being called. If it does work, then the issue is with the curl command.

5. Debugging:

• If the problem persists, try redirecting the output of the curl command to a file to see if there are any error messages:
  • /usr/bin/kitty -e "/usr/bin/curl wttr.in/New_York > /tmp/weather.log 2>&1"
  • Then, check the /tmp/weather.log file for any error messages.

Key Points:

• Full paths are crucial.
• Environment variables can cause unexpected behavior.
• Permissions can also block execution.
• Debugging by redirecting output can reveal errors.
