To exclude a directory that you specified, use the –exclude-dir with -R or -r option. For example, I want to exclude the word function that appears at the beginning of a line $ grep -v '^function' fn.txtīecause the word function appears at the ending of the line, it won’ be excluded. If you only want to exclude words that show at the beginning of a line. If you want to specify multiple strings at once, let’s use the -e option.įor example, I want to exclude limit and abcd string: $ grep -v -e limit -e abcd fn.txt If the string that you wanna search contains space, you must use parentheses or quotes.įor example, I want to exclude the line that contains string ab cd: $ grep -v 'ab cd' fn.txt Now I have a file named fn.txt.that contains the following contents:įor example, I want to exclude the line that contains the word function: $ grep -v function fn.txtĪs you can see, the line that contains the word function is filtered out. To display lines that don’t match the search pattern, let’s use the -v option.
Grep exclude how to#
And it is also very important to exclude words and patterns or dictionaries and files.īelow is the guide on how to exclude in grep as we go through below. The grep command is used to filter out input files that match a regular expression then print to standard output. Grep exclude binary files, we can use grep -I option, it can ignore binary files when searching.Grep stands for “global regular expression print” and it is a useful command in Linux. When we use the grep command pattern search, we often find some binary files, these are not what we need, so we need to exclude these binary files. ➜ grep -exclude "test.log" -exclude "m.log" "grep" *.log In the following example, we will use the grep –exclude option to exclude one or more files during pattern search. ➜ grep -exclude "file1" -exclude "file1" "keyword" files Grep - exclude syntax # grep exclude a file Grep exclude file, as with excluding directories, we can use the grep –exclude option, which will exclude files matching the given file name pattern from the search. ➜ grep -exclude-dir "test" -exclude-dir "backup" -R "grep". In the following example, we use grep –exclude-dir to exclude one or more directories. ➜ grep -exclude-dir "directory1" -exclude-dir "directory2" -R "keyword". ➜ grep -exclude-dir "directory" -R "keyword". Grep –exclude-dir syntax # grep exclude a directory
Recursively search subdirectories listed. If -R is specified, it excludes directories matching the given filename pattern from the search.
Grep –exclude-dir excludes directories matching the given file name pattern from the search. Grep exclude directories, we can use the grep –exclude-dir option, which needs to be used with the grep -R option. ➜ ~ grep -i 'use' test.log | grep -v "option" | grep -v "find" Grep exclude directory In the following example, we will use a pipeline with grep to exclude multiple keywords. ➜ ~ grep -i 'use' test.log | grep -v "option" In the following example, we will use grep to search for keywords and exclude specific keyword. ➜ grep -v "keyword1" file | grep -v "keyword2" |.
Grep -v syntax # grep excludes a single keyword Selected lines are those not matching any of the specified patterns.
We can use the grep -v option, which can which can invert the match.
