For a regular expression pattern, this is like parenthesizing the pattern and then surrounding it with ^ and $. -y Obsolete synonym for -i. General Output Control -c, --count Suppress normal output; instead print a count of matching lines for each input file. With the -v, --invert...
Surround the matched (non-empty) strings, matching lines, context lines, file names, line numbers, byte offsets, and separators (for fields and groups of context lines) with escape sequences to display them in color on the terminal. The colors are defined by the environment variable GREP_COL...
The solution can be found in GNU's Context Line Control. If you want an equal number of lines on both sides, you can use a single context number. By combining it with the flag (-C), you will have numbered matches with surrounding context. I'm attempting to obtain outputs in the form...
