# Globbing¶

Globbing is the process of matching paths according to the rules used by the Unix shell.

Generally speaking, you can think of a glob pattern as a path containing one or more wildcard patterns, separated by forward slashes.

## Matching Files and Directories¶

In a glob pattern, A * means match anything text in a filename. A ? matches any single character. A ** matches any number of subdirectories, making the glob recusrive. If the glob pattern ends in a /, it will only match directory paths, otherwise it will match files and directories.

Note

A recursive glob requires that PyFilesystem scan a lot of files, and can potentially be slow for large (or network based) filesystems.

Here’s a summary of glob patterns:

*
Matches all files in the current directory.
*.py
Matches all .py file in the current directory.
*.py?
Matches all .py files and .pyi, .pyc etc in the currenct directory.
project/*.py
Matches all .py files in a directory called project.
*/*.py
Matches all .py files in any sub directory.
**/*.py
Recursively matches all .py files.
**/.git/
Recursively matches all the git directories.

## Interface¶

PyFilesystem supports globbing via the glob attribute on every FS instance, which is an instance of BoundGlobber. Here’s how you might use it to find all the Python files in your filesystem:

for match in my_fs.glob("**/*.py"):
print(f"{match.path} is {match.info.size} bytes long")


Calling .glob with a pattern will return an iterator of GlobMatch named tuples for each matching file or directory. A glob match contains two attributes; path which is the full path in the filesystem, and info which is an fs.info.Info info object for the matched resource.

## Batch Methods¶

In addition to iterating over the results, you can also call methods on the Globber which apply to every matched path.

For instance, here is how you can use glob to remove all .pyc files from a project directory:

>>> import fs
>>> fs.open_fs('~/projects/my_project').glob('**/*.pyc').remove()
