  • sed -i -e 's/"disabled": true/"disabled": false/g' /opt/wildduck/emails/00-example.json

• The command you provided uses sed, a stream editor for filtering and transforming text. Here's a breakdown of the command:

  • sed: The command itself, used for text processing.
  • -i: This option tells sed to edit files in place. That means it will modify the original file directly rather than outputting the changes to the console or a new file.
  • -e: This option allows you to specify the script to be executed. In this case, it indicates that the following argument is a sed script.
  • 's/"disabled": true/"disabled": false/g': This is the sed script itself:
    • s: Stands for "substitute," indicating that we want to replace text.
    • /"disabled": true/: This is the pattern we want to match. It looks for the string "disabled": true.
    • /"disabled": false/: This is the replacement string, specifying that we want to replace matches of the first string with this.
  • g: Stands for "global," meaning that the substitution should happen for all occurrences in each line of the file, not just the first one.
  • /opt/wildduck/emails/00-example.json: This is the path to the file that sed will modify.
