print lines matching a pattern
|
-R, -r, --recursive
Read all files under each directory, recursively; this is equivalent to the -d recurse option.
|
-i, --ignore-case
Ignore case distinctions in both the PATTERN and the input files. (-i is specified by POSIX.)
|
-n, --line-number
Prefix each line of output with the 1-based line number within its input file. (-n is specified
by POSIX.)
|
grep searches the named input FILEs (or standard input if no files are named, or if a single hyphen-minus
(-) is given as file name) for lines containing a match to the given PATTERN. By default, grep prints
the matching lines.
