pattern
This command has the following options:
| Option | Interpretation |
|---|---|
-i, --ignore-case
| Ignores case distinctions in both the PATTERN and the input
files. |
-w, --word-regexp
| Selects only those lines containing matches that form whole words. The test is that the matching substring must either be at the beginning of the line, or preceded by a non-word constituent character. Similarly, it must be either at the end of the line or followed by a non-word constituent character. Word-constituent characters are letters, digits, and the underscore. |
-n, --line-number
| Prefixes each line of output with the line number within its input file. |
-x, --line-regexp
| Selects only those matches that exactly match the whole line. |
-v, --invert-match
| Inverts the sense of matching, to select non-matching lines. |
--help
| Displays the online help for this command. |
