Grep provides a -r option for the recursive search. Grep recursive search in all subdirectories of a directory Now that you know that, let's see how you can perform a recursive search with grep so that it also looks into the files in the subdirectories. If you are not in the same directory where you want to perform, you can specify the directory path and end it with /* grep search_term directory_path/*īasically, you are using the wild card to expand on all the elements (files and directories) of the given directory. Search in all files of a directory with grep Since you cannot directly grep search on a directory, it will show "XYZ is a directory" error along with search results. This will search in all the files in the current directories, but it won't enter the subdirectories. The wild card actually substitutes with the name of all the files and directories in the current directory. To search for the word 'simple' in all the files of the current directories, just use wild card (*). Except empty.txt, all files contain the term 'simple' on which I'll perform the grep search. Here's the directory structure I am going to use in this example. Let me show you all this in details with proper examples so that it is easier for you to understand. You may also specify the directory path if you are not in the directory where you want to perform the search: grep -r search_term directory_path You can make grep search in all the files and all the subdirectories of the current directory using the -r recursive search option: grep -r search_term. It only searches in all the files in the current directory. If you want to search all the files in a directory with grep, use it like this: grep search_term * Usually, you run grep on a single file like this: grep search_term filename To show the list of all files and folders in a Linux system, try the “ls” command along with the flag ‘-a” as shown below.Grep is an excellent tool when you have to search on the content of a file. The output will show only the directories but not the files. Open the command-line shell and write the ‘ls” command to list only directories. The find command often precedes xargs in a pipeline. How to Use the xargs Command With Examples We can exclude various patterns using the -v flag and repetition of the -e flag: $ grep -ivw -e ‘the’ -e ‘every’ /tmp/baeldung-grep Time for some thrillin’ heroics. The -e flag allows us to specify multiple patterns through repeated use. ![]() How do I exclude multiple words from grep? ![]() This option of grep only shows filenames that contain matching text. Since many files contain database references, you might get a lot of data on output, so if you are only interested in all the files containing matching text, you can use the grep -l option. The directory “bit” will be excluded from the find search! We can exclude directories by using the help of “path“, “prune“, “o” and “print” switches with find command. Exclude Multiple Files or Directories If the number of the files and/or directories you want to exclude is large, instead of using multiple –exclude options you can specify the files and directories you want to exclude in a file and pass the file to the –exclude-from option.
