If ACTION is skip, devices are silently skipped. By default, ACTION is read, which means that devices are read as if they were ordinary files. If an input file is a device, FIFO or socket, use ACTION to process it. With the -v, -invert-match option (see below), count non-matching lines. Suppress normal output instead print a count of matching lines for each input file. WHEN may be ' never', ' always', or ' auto' Surround the matching string with the marker find in GREP_COLOR environment variable. Warning: grep -binary-files=text might output binary garbage, which can have nasty side effects if the output is a terminal and if the terminal driver interprets some of it as commands. If TYPE is text, grep processes a binary file as if it were text this is equivalent to the -a option. If TYPE is without-match, grep assumes that a binary file does not match this is equivalent to the -I option. By default, TYPE is binary, and grep normally outputs either a one-line message saying that a binary file matches, or no message if there is no match. If the first few bytes of a file indicate that the file contains binary data, assume that the file is of type TYPE. Print the byte offset in the input file before each line of output. Places a line containing - between contiguous groups of matches. Print NUM lines of leading context before matching lines. Process a binary file as if it were text this is equivalent to the -binary-files=text option. Print NUM lines of trailing context after matching lines.
