Now that we’ve seen that PCRE is more powerful than BRE and ERE, we should note that not all grep implementations support the -P option.Can one machine consume all available bandwidth? Ex. So next, let’s match lines containing “ Eric“, “ Kent“, and “ and” using grep -P: $ grep -P '(?=.*Kent)(?=.*Eric)(?=.*and)' input.txt However, if our grep supports the -P option, we can add more lookahead assertions to the pattern to solve the problem. Enclose the string youre looking for in double quotation marks. Therefore, this approach isn’t ideal if we want to match more than two strings in the logical “And” relationship. The simplest fundamental patterns are literal strings. In this article, we’re going to show you how to use GNU grep to search for multiple strings or patterns. 66 then 67 continue 68 fi 69 70 grep -Fw word 'WORDFILE' Match whole. For example, to search for warnings and errors through all. 39 40 Translate output of 'strings' command with multiple passes of 'tr'. If you want to monitor log files in one directory or if you want to search through all text files, use an asterisk and the file extension instead of a file name. Moreover, if we want to match four strings in the “And” scenario, we have 24 permutations, and five strings will lead to 120 permutations. grep is a powerful command-line tool that allows you to searches one or more input files for lines that match a regular expression and writes each matching line to standard output. You can use grep to search multiple strings in a certain type of file only. Obviously, writing this pattern isn’t straightforward and it’s error-prone. There's no shame in that, particularly because a regular expression (using egrep) would be ungainly since you seem to imply you want order independence. The easiest way to put these sorts of expressions together is with multiple pipes. Then we have six permutations: ‘ A.*B.*C|A.*C.*B|B.*A.*C|B.*C.*A|C.*A.*B|C.*B.*A‘. 1 Add a comment 4 Answers Sorted by: 29 This looks like three questions. If you want to search multiple patterns or strings in a particular file, use the grep functionality to sort within a file with the help of more than one input word in the command. Let’s say we need to add one more string, ‘ C‘, to the matching list. In this article, we will show you how to use grep to search multiple strings and patterns at once in Linux. Here, we put the permutations of two words in the pattern: ‘ A.*B|B.*A‘. An example of using grep Let’s take a file called somefile. Let’s quickly revisit how we match two strings in the “And” scenario: ‘ Eric.*Kent|Kent.*Eric‘.
