另一种肮脏的方式:

grep -A80 -B80 --color FIND_THIS IN_FILE

我做了一个

alias grepa='grep -A80 -B80 --color'

把bashrc打印出来。

使用ripgrep，即rg: https://github.com/BurntSushi/ripgrep

rg - passthru……

颜色是默认的:

  rg -t tf -e  'key.*tfstate' -e dynamodb_table
       --passthru
       Print both matching and non-matching lines.

       Another way to achieve a similar effect is by modifying your pattern to
       match the empty string. 
       For example, if you are searching using rg foo then using 
       rg "^|foo" instead will emit every line in every file searched, but only
       occurrences of foo will be highlighted. 
       This flag enables the same behavior without needing to modify the pattern.

亵渎神明，没错，但格雷普已经沾沾自喜了。

安装ripgrep

你再也回不去了。

正如grep -E '|pattern'已经被建议的那样，只是想澄清一下，它也可以突出显示整行。

例如:tail -f somelog | grep——color -E '| \[2\]。*'(特别是-E '|部分):

我使用的rcg来自“Linux服务器黑客”，O'Reilly。它非常适合你想要的东西，可以用不同的颜色突出多个表情。

#!/usr/bin/perl -w
#
#       regexp coloured glasses - from Linux Server Hacks from O'Reilly
#
#       eg .rcg "fatal" "BOLD . YELLOW . ON_WHITE"  /var/adm/messages
#
use strict;
use Term::ANSIColor qw(:constants);

my %target = ( );

while (my $arg = shift) {
        my $clr = shift;

        if (($arg =~ /^-/) | !$clr) {
                print "Usage: rcg [regex] [color] [regex] [color] ...\n";
                exit(2);
        }

        #
        # Ugly, lazy, pathetic hack here. [Unquote]
        #
        $target{$arg} = eval($clr);

}

my $rst = RESET;

while(<>) {
        foreach my $x (keys(%target)) {
                s/($x)/$target{$x}$1$rst/g;
        }
        print
}

或者你也可以使用银色搜索器

ag <search> --passthrough

以下是我的方法，灵感来自@kepkin的解决方案:

# Adds ANSI colors to matched terms, similar to grep --color but without
# filtering unmatched lines. Example:
#   noisy_command | highlight ERROR INFO
#
# Each argument is passed into sed as a matching pattern and matches are
# colored. Multiple arguments will use separate colors.
#
# Inspired by https://stackoverflow.com/a/25357856
highlight() {
  # color cycles from 0-5, (shifted 31-36), i.e. r,g,y,b,m,c
  local color=0 patterns=()
  for term in "$@"; do
    patterns+=("$(printf 's|%s|\e[%sm\\0\e[0m|g' "${term//|/\\|}" "$(( color+31 ))")")
    color=$(( (color+1) % 6 ))
  done
  sed -f <(printf '%s\n' "${patterns[@]}")
}

这接受多个参数(但不允许自定义颜色)。例子:

$ noisy_command | highlight ERROR WARN
