grep:
Matcher Selection:
arguments:
- ["E","--extended-regexp","Interpret PATTERN as an extended regular expression"]
- ["F","--fixed-strings","Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched."]
- ["G","--basic-regexp","Interpret PATTERN as a basic regular expression (BRE, see below). This is the default."]
- ["P","--perl-regexp","display $ at end of each line"]
Matching Control:
arguments:
- ["e PATTERN","--regexp=PATTERN","Use PATTERN as the pattern. This can be used to specify multiple search patterns, or to protect a pattern beginning with a hyphen (-)."]
- ["f FILE","--file=FILE","Obtain patterns from FILE, one per line. The empty file contains zero patterns, and therefore matches nothing."]
- ["i","--ignore-case","Ignore case distinctions in both the PATTERN and the input files."]
- ["v","--invert-match","Invert the sense of matching, to select non-matching lines."]
- ["w","--word-regexp"," Select 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."]
- ["x","--line-regexp","Select only those matches that exactly match the whole line."]
