Linux find files by mask

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.

Get list of all files by mask in terminal

I want to find all *.h , *.cpp files in folders with defined mask, like */trunk/src* . So, I can find separately *.h and *.cpp files:

find . -path "*/trunk/src/*.h" find . -path "*/trunk/src/*.cpp" 

What is the best way to get the file-list both of types ( *.h and *.cpp )? PS I’d like to pipe the list to grep .

find . -path '*/trunk/src/*.h' -o -path '*/trunk/src/*.cpp' 

find . -path '*/trunk/src/*' \( -name '*.h' -o -name '*.cpp' \) 

If you want to run grep on these files:

find . \( -path '*/trunk/src/*.h' -o -path '*/trunk/src/*.cpp' \) -exec grep PATTERN <> + 

find . -path '*/trunk/src/*' \( -name '*.h' -o -name '*.cpp' \) -exec grep PATTERN <> + 

In bash, turn on the globstar option so that ** matches any level of subdirectories. You can do this from your ~/.bashrc . Also turn on the extglob options to activate ksh extended patterns.

grep PATTERN **/trunk/src/**/*.@(h|cpp) 

Beware that bash versions up to 4.2 follow symlinks to directories when you use ** .

Zsh makes this easier, you don’t need to set any options and can just type

grep PATTERN **/trunk/src/**/*.(h|cpp) 

If the command line is too long, and you’re on Linux or other platform with GNU grep, you can make grep recurse instead of the shell to save on the command line length.

grep -R --include='*.cpp' --include='*.h' PATTERN **/trunk/src
