4/9/2023 0 Comments Find file name linux![]() ![]() Most commands demonstrated in this article work with other implementations of find, but should you try a command on a platform other than Linux and get unexpected results, try downloading and installing the GNU version. This article uses GNU find from the findutils package because it's readily available and pretty popular. The GNU find command, for instance, has features that the BSD or Busybox or Solaris find command might not have or does have but implements differently. However, not all find commands are exactly alike. Simply put, you already have find installed as long as you're running Linux, BSD, or macOS. The find command is defined by the POSIX specification, which creates the open standard by which POSIX systems (including Linux, BSD, and macOS) are measured. Free online course: RHEL Technical Overview.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. -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. 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.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' ![]()
