  • Replace a regex pattern in a specific directory in files filtered with a case-insensitive glob pattern:

fastmod regex replacement --dir path/to/directory --iglob {{'**/*.{js,json}'}}

  • Replace for an exact string in .js or JSON files:

fastmod --fixed-strings exact_string replacement --extensions json,js
