print lines matching a pattern |
-i, --ignore-case Ignore case distinctions in both the PATTERN and the input files. (-i is specified by POSIX.) |
-C NUM, -NUM, --context=NUM Print NUM lines of output context. Places a line containing a group separator (--) between contiguous groups of matches. With the -o or --only-matching option, this has no effect and a warning is given. File and Directory Selection -a, --text Process a binary file as if it were text; this is equivalent to the --binary-files=text option. |
