to search the directory you’re currently in: sudo find. In our example, the search term is filename. The find command searches everything under the /home directory (including all user directories) for your search term. If you are not certain where you want to look, you can widen the search location.įor example, if you have two user accounts and you don’t remember which one you saved a file to, you can enter: sudo find /home filename This command searches the user account in the home directory. Searching for files based on their location string can be a simple command such as: sudo find /home/user filename The find command also enables you to define search parameters, options, and locations with a high level of accuracy. The find command lists all instances of the character string you included in your search. It can be used to control the behavior and optimize the search process. Options – This attribute is not a mandatory element of the find command.Name – Represents the string of text (or other data) you are searching for.Action – The a ction attribute executes a command on the search results.Expression – Tells find what category of information it’s supposed to look for.Location – Instructs find where to start looking for your search term.The basic syntax of the find command uses the following format: find Access to a terminal window/command line.If more than one match was found, then each line number will be appended to the filename. Demos/snippets/multiComptSigNeur.py:268Īnd voila, it generates the path of matched files and line number at which the match was found.

python/moose/multiscale/core/mumbl.py:206 Only those files which matches this regular expression will be considered.įor example, if I want to search Python files with the extension py containing Pool( followed by word Adaptor, I do the following. This is another regular expression which works on a filename. The third argument, file_pattern, is optional. We use the regular expression format defined in the Python re library. The second argument, pattern_to_search, is a regular expression which we want to search in a file. The first argument, path, is the directory in which we will search recursively. This is how one should use this script./sniff.py path pattern_to_search I wrote a Python script which does something similar.

type f -name "*.*" -print0 | xargs -null grep -with-filename -line-number -no-messages -color -ignore-case "searthtext"Īnd if you have an idea what the file type is you can narrow your search down by specifying file type extensions to search for, in this case. "/home" depending where you actually want to search.Įxpanding the grep a bit to give more information in the output, for example, to get the line number in the file where the text is can be done as follows: find. So in the examples above, you'd better replace ' /' by a sub-directory name, e.g. Warning: unless you really can't avoid it, don't search from '/' (the root directory) to avoid a long and inefficient search! Note: You can add 2>/dev/null to these commands as well, to hide many error messages. The Silver Searcher: ag 'text-to-find-here' / -l RipGrep - fastest search tool around: rg 'text-to-find-here' / -l Better try them, provided they're available on your platform, of course: Faster and easier alternatives The find command is often combined with xargs, by the way.įaster and easier tools exist for the same purpose - see below. \ 2>/dev/nullįind is the standard tool for searching files - combined with grep when looking for specific text - on Unix-like platforms. This will only search through those files which have.-e is the pattern used during the searchĪlong with these, -exclude, -include, -exclude-dir flags could be used for efficient searching:.-l (lower-case L) can be added to just give the file name of matching files.Do the following: grep -rnw '/path/to/somewhere/' -e 'pattern'
