# lid
|
|
|
|
> Query an ID database for tokens matching a pattern.
|
|
> Note: An ID database must first be built using `mkid`.
|
|
> More information: <https://www.gnu.org/software/idutils/manual/html_node/lid-invocation.html>.
|
|
|
|
- List all tokens and their file locations in the ID database:
|
|
|
|
`lid`
|
|
|
|
- Find files containing a specific token:
|
|
|
|
`lid {{token}}`
|
|
|
|
- Find tokens matching a pattern, ignoring case:
|
|
|
|
`lid {{[-i|--ignore-case]}} {{token}}`
|
|
|
|
- Find tokens matching an extended regular expression:
|
|
|
|
`lid {{[-r|--regexp]}} "{{pattern}}"`
|
|
|
|
- Output matching lines in grep-style format:
|
|
|
|
`lid {{[-R|--result]}} grep {{token}}`
|
|
|
|
- Find tokens that appear only once (useful for finding unused definitions):
|
|
|
|
`lid {{[-F|--frequency]}} 1`
