I love it because it defaults to recursive searching of directories and does so much smarter than grep -r , supports full Perl regular expressions rather than the POSIXish regex 3 , and has a much nicer context display when searching many files.

It's better than grep because you can highlight each match with its own color. You can now use the alias like this: " ifconfig grepe inet " or " grepe css index.

It is designed to add color highlights to a text stream. Given a regex and a color e. Or you can achieve the same thing by using a regex with N groups parenthesised parts of the regex , followed by a comma separated list of N colors. It's perfect for what you want and can highlight multiple expressions each with different colours.

As grep -E ' pattern' has already been suggested, just wanted to clarify that it's possible to highlight a whole line too. To highlight patterns while viewing the whole file, h can do this. To grep and use 1 color for each pattern, cxpgrep could be a good fit. Here is a shell script that uses Awk's gsub function to replace the text you're searching for with the proper escape sequence to display it in bright red:.

One other answer mentioned grep's -Cn switch which includes n lines of Context. I recently discovered ccze which is a more powerful colorizer. My only complaint is that it is screen-oriented like less , which I never use for that reason unless you specify the -A switch for "raw ANSI" output. It is still my favorite since it is so simple to customize in an alias. Alternatively you can use The Silver Searcher and do. One of advantage of using sed : You could send a alarm beep on console, using bell ascii character 0x7.

I often use sed like:. If you want highlight several patterns with different colors see this bash script. Here's my approach , inspired by kepkin's solution:. Option -C will do the trick in the absence of an option to display all context lines. Most other grep variants support this too. However: 1 no output is produced when no match is found and 2 this option has a negative impact on grep's efficiency: when the -C value is large this many lines may have to be temporarily stored in memory for grep to determine which lines of context to display when a match occurs.

Note that grep implementations do not load input files but rather reads a few lines or use a sliding window over the input. The "before part" of the context has to be kept in a window memory to output the "before" context lines later when a match is found.

However, 1 these patterns don't show non-matching lines highlighted as context and 2 this can't be used in combination with some other grep options, such as -F and -w for example.

So none of these approaches are satisfying to me. I'm using ugrep , and enhanced grep with option -y to efficiently display all non-matching output as color-highlighted context lines. Other grep-like tools such as ag and ripgrep also offer a pass-through option. For example, here is what option -y shows when combined with -Q interactive query UI to enter patterns :.
