![]() ![]() 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. If you really resist on your file name filtering (.log) and you want recursive (files are not all in the same directory. Or on Linux: cd / grep -r somethingtosearch /temp. Running grep 'string' /path/to/dir is supposed to be able to do this, I've read, but it gives me the error: grep: dir: Is a directory Next, I tried running grep on multiple files. If you want to see the full paths, I would recommend to cd to the top directory (of your drive if using Windows) cd C: grep -r somethingtosearch C:UsersOzzeshtemp. This is how one should use this script./sniff.py path pattern_to_search 56 I want to search for a string of text in all files in a directory (and not its subdirectories I know the -r option does that, but that is not what I want). I wrote a Python script which does something similar. -print0 and -null on the other side of the | (pipe) are the crucial ones, passing the filename from the find to the grep embedded in the xargs, allowing for the passing of filenames WITH spaces in the filenames, allowing grep to treat the path and filename as one string, and not break it up on each space.-type f specifies that you are looking for files.( -name " *.pas" -o -name " *.dfm" ) : Only the *.pas OR *.dfm files, OR specified with -o in the find specifies from the current directory. Are there directories within that directory Or just files It looks like xxd only operates on one file at a time so youll need a loop (which is likely true if you want to be able to report which file matched easily). type f \( -name "*.pas" -o -name "*.dfm" \) -print0 | xargs -null grep -with-filename -line-number -no-messages -color -ignore-case "searchtext" 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.Ä®xpanding 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. To find a file in Linux based on its content using grep, we can follow the syntax: grep -rnw ââ -e ââ.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. grep mystring /.html for recursive search (excluding any file in current dir). \ 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. If you want to get the line numbers, you may want to look into the enumerate function. def grep (filepath, regex): regObj re.compile (regex) res with open (filepath) as f: for line in f: if regObj.match (line): res.append (line) return res. -e is the pattern used during the searchĪlong with these, -exclude, -include, -exclude-dir flags could be used for efficient searching: Now for the grep part, you can loop over the file with the open function.print0 tells find to print a null character after each file it finds xargs -0 reads from standard input and runs the. You have to escape the first so that the shell does not interpret it. -l (lower-case L) can be added to just give the file name of matching files. eml.gz files in the current directory, you can use: find.Don't forget there is always a man page from find.Do the following: grep -rnw '/path/to/somewhere/' -e 'pattern' If you don't do this last -exec you don't know what file he grep the text from. Sorry, I will try to make things a bit more clear :įind /tmp -name \*ipt -exec grep pall \ " has the same syntax and executes the ls -l command for the current result. ![]()
