All files, including subdirectories, will be searched. The execution of the above commands will locate the perl binary and display the full path(s) to it. There is a -r option that allows you to search directories recursively. For example, to find a certain file in the whole server, it would be best to use an alternative command – whereis or which: whereis perl In some rare cases, find and grep may prove not useful. For example, the line below will only output configuration.php result: ls -la | grep configuration.php Grep can also be used to filter the results from other commands. This will display the filenames containing the word “ database”, but will not actually list the line containing it. To only list the file names containing the string you are searching but omit the line containing it, you can use the -l argument: grep -l "database" * This will make grep look recursively ( -r option) and provide the result in a human-readable format ( -H option) for the string “ database” in all (*) files under the current working directory. If you don’t know which file contains the text, you can use: grep -r -H "database" * The above command instructs grep to look for the string “ database” in the configuration.php file and display the containing line. ![]() For a full list it is recommended to check the manual pages by typing man grep.Īn example of using grep to find a certain text can be found below: grep "database" configuration.php Grep is a very powerful tool and accepts various command line arguments. however, the question says that the file name should only contain lowercase English letters but not the slash. file nsrfile grub2-file systemd-tmpfiles. pdf files and then you can use the search engine tools of that indexer to get the content of the pdf. and here's some part of the result I get. You can do that either per file with tools such as pdf2text and grep the result, or you run an 'indexer' (look at or lucene) which builds an searchable index out of your. The command you should be using, in this case, is grep. For example, nsrfile and file should be in the output. ![]() You can also search for a given text in the content of the files as well. Or if you want to filter only files modified in the last 2 days, you would need to use: find. If you would like to list only directories and leave all files out of the result: find. ![]() The following example shows how to search through all. If you are uncertain about the file name or would like to match a part of the name, you can use a wildcard pattern: find. To recursively search for a pattern, invoke grep with the -r option (or -recursive ). To search for all the lines of a file that do not contain a certain string, use the -v option to grep. Find is a very powerful tool and accepts various arguments allowing you to specify the exact search term (i.e search by name, by type or even by modified time).įor example, to search for a file called myFile.txt under the current folder (and all subfolders), you would need to use the following command: find. In order to search for a file location, you can use the find command. SSH provides two different commands, which can be used to accomplish this. In some cases, you would need to find the location of a given file or to search for a certain text in all files under a directory.
