$ gh copilot explain 'gh pr list | awk "{ print \$1 }"'

Welcome to GitHub Copilot in the CLI!
version 0.5.3-beta (2023-11-09)

I'm powered by AI, so surprises and mistakes are possible. Make sure to verify any generated code or suggestions, and share feedback so that we can learn and improve.

Explanation:

  • gh pr list uses the gh command-line tool to list pull requests.
  • | pipes the output of the previous command to the next command.
  • awk is a text processing tool.
    • "{ print \$1 }" is an awk script that prints the first field of each line, which corresponds to the first column in this case.
      • \$1 represents the first field/column of each line. The backslash is used to escape the dollar sign since it has a special meaning in the shell.
