How to find file in linux recursive

How can I recursively find all files in current and subfolders based on wildcard matching?

find needs a starting point, so the . (dot) points to the current directory.

I know this is tagged as linux but this is worth mentioning: the path is required for on other *nix variants that aren’t linux. On linux, the path is optional if you want to use dot.

@Seatter «foo*» tells find to look for all files that start with «foo». It is just his example. You could use «gpio*» to find all files who’s names start with gpio, or just «gpio1» to find all files named gpio1.

note that the «foo*» is in quotes so the shell doesn’t expand it before passing it to find. if you just did find . foo* , the foo* would be expanded AND THEN passed to find.

Also useful: If you don’t want to be notified about directories you don’t have permission to (or other errors), you can do find . -name «foo*» 2>/dev/null

Piping find into grep is often more convenient; it gives you the full power of regular expressions for arbitrary wildcard matching.

For example, to find all files with case insensitive string «foo» in the filename:

find also has the -iname , -regex , and -iregex flags for case-insensitive wildcard, regex, and case-insensitive regex matching, so piping to grep is unnecessary.

However, piping to grep -v can allow you to use simple strings or regexes to remove entries you don’t want.

@iobender — Sadly, I can tell you from experience that not all systems come with a find command that supports those options. Sometimes grep becomes the only option.

One important caveat here is that if you’re using find on a directory that contains A LOT of files (eg; «) then this can be quite slow.

find will find all files that match a pattern:

However, if you want a picture:

fd

In case find is too slow, try the fd utility — a simple and fast alternative to find written in Rust.

In a few cases, I have needed the -L parameter to handle symbolic directory links. By default symbolic links are ignored. In those cases it was quite confusing as I would change directory to a sub-directory and see the file matching the pattern but find would not return the filename. Using -L solves that issue. The symbolic link options for find are -P -L -H

L switch is very helpful. Many times user do not have any idea about underlying directories, whether they are softlinked or are normal directories. So in case of doubt, it always good to use L option. At least, it has always helped me.

In the wildcard-match you can provide the string you wish to match, e.g., *.c (for all C files).

Your answer is the first most correct here as it only searches files as specified. The others not specifying type will return directories.

By default, find detect symbolic file links (but not the ones in symbolic directory links). -type f will cause find to not detect symbolic file links. If you also want to include symlinks that point to a file, use -L : find -L -type f . Don’t use -type f,l since it will also include symbolic directory links.

If your shell supports a new globbing option (can be enabled by: shopt -s globstar ), you can use:

to find any files or folders recursively. This is supported by Bash 4, zsh and similar shells.

Personally I’ve got this shell function defined:

Note: Above line can be pasted directly to shell or added into your user’s ~/.bashrc file.

Then I can look for any files by typing:

Alternatively you can use a fd utility with a simple syntax, e.g. fd pattern .

@Broncha Because you need to activate the extended globbing by shopt -s globstar command. This is supported in Bash, zsh and similar shells.

find path/to/dir -name "*.ext1" -o -name "*.ext2" 

Explanation

1. The first parameter is the directory you want to search.
2. By default find does recursion.
3. The -o stands for -or . So above means search for this wildcard OR this one. If you have only one pattern then no need for -o .
4. The quotes around the wildcard pattern are required.

find . -type f -name 'text_for_search' 

If you want use a regular expression, use -iname :

find . -type f -iname 'text_for_search' 

The default way to search for files recursively, and available in most cases is

It starts recursively traversing for filename or pattern from within the current directory where you are positioned. With the find command, you can use wildcards, and various switches. To see the full list of options, type

Or if man pages aren’t available at your system:

However, there are more modern and faster tools than find, which are traversing your whole filesystem and indexing your files. One such common tool is locate or slocate/mlocate. You should check the manual of your OS on how to install it, and once it’s installed, it needs to initiate the database. If the install script doesn’t do it for you, it can be done manually by typing

And, to use it to look for some particular file, type:

Or, to look for a filename or pattern from within the current directory, you can type:

pwd | xargs -n 1 -I <> locate "filepattern" 

It will look through its database of files and quickly print out path names that match the pattern that you have typed. To see the full list of locate’s options, type: locate —help or man locate

Additionally, you can configure locate to update its database on scheduled times via a cron job, so a sample cron which updates the database at 1 AM would look like:

These cron jobs need to be configured by root, since updatedb needs root privileges to traverse the whole filesystem.

How do I use grep to find a file in Linux?

3. -user userName – The file’s owner is userName.

Is grep recursive by default?

For instance, it’s recursive by default and automatically ignores files and directories listed in . gitignore , so you don’t have to keep passing the same cumbersome exclude options to grep or find. but grep -r is a better answer. Recurse in directories only searching file matching PATTERN .

How do I see all files in Linux?

Linux Find Recursive

Recursive directory listing allows you to view and find files that are nested inside other subdirectories.

One of the commands that are built for that purpose is the tree command. A tree is a simple and powerful directory listing utility. You can specify the level of depth that you wish to show in a single command.

Tree, as the name suggests, allows you to show files in nested directories in a tree-like format. It also gives you details about the specified path, including the total number of files and directories, etc.

To install it, use your system package manager:

You can then use the tree command followed by the path to the target directory.

For example, the command below shows all the files and directories inside the /var/logs directory:

To find all the files and directories, including hidden files, you can use the -a flag with the tree command:

Using Find

You can also use the find command followed by the target directory and the file you wish to locate.

For example, to locate the file access.logs in the root directory, use the command:

The command will start in the root directory and recursively search all the subdirectories and locate any file with the specified name.

To find any files ending with a specific extension, run the command:

The command will start in the current working directory as specified by the period and recursively search for all files ending with the .txt extension.

Using fd Command

The fd command is a free, open-source utility that is developed as an alternative to the find command.

It is very fast and user-friendly and has incredible functionality. It’s a great tool when you need to locate a file that is nested inside a series of subdirectories.

To install it, run the commands:
