说明
lid queries an ID database to find tokens matching a specified pattern. Part of GNU idutils, it searches a pre-built token database to quickly locate identifiers across source files. An ID database must first be built using the mkid command. The database indexes all tokens (identifiers, keywords, strings) found in source files, enabling fast lookups without rescanning the entire codebase. Patterns are interpreted flexibly: if a pattern contains regex metacharacters, lid performs a regex substring search; otherwise it conducts a literal word search. When no pattern is given, all database entries are listed.
参数
- -f _filename_
- Specify which ID database file to read
- -i, --ignore-case
- Perform case-insensitive pattern matching
- -l, --literal
- Treat the pattern as a literal string (no regex)
- -r, --regexp
- Force regular expression pattern matching
- -w, --word
- Match whole words only (non-substring search)
- -s, --substring
- Perform substring search
- -k _style_
- Control output format: token, pattern, or none
- -R, --result _style_
- Control result type: filenames, grep (show lines), edit (open in editor), or none
- -F, --frequency _range_
- Match tokens by occurrence frequency (e.g., 1 for tokens appearing once)
