Check for typos in all text files in the current directory, recursively:

codespell {{[-w|--write-changes]}}

Skip files with names that match the specified pattern (accepts a comma-separated list of patterns using wildcards):

codespell {{[-S|--skip]}} "{{pattern}}"

Use a custom dictionary file when checking (--dictionary can be used multiple times):

codespell {{[-D|--dictionary]}} {{path/to/file.txt}}

Do not check words that are listed in the specified file:

codespell {{[-I|--ignore-words]}} {{path/to/file.txt}}

Do not check the specified words:

codespell {{[-L|--ignore-words-list]}} {{ignored_word1,ignored_word2,...}}

Print 3 lines of [C]ontext around, [B]efore, or [A]fter each match:

codespell {{--context|--before-context|--after-context}} 3

Check file names for typos, in addition to file contents:
