Often you may want to use Bash to delete all files in a directory that do not have an extension.
You can use the following syntax to do so:
find . -type f ! -name "*.?*" -delete
This particular example will delete all files in the current directory that do not have an extension.
Here is what the various commands do:
- find .: Match all items in current directory
- -type f: Match only the files
- ! -name “*.?*”: Match only files that do not have an extension
- -delete: Delete all matched files
Note that you can also replace find . with find /some/directory/path to match all files in a specific directory.
Note: This syntax will also delete any files that end with a period ( . ) followed by no extension.
The following example shows how to use this syntax in practice.

- c:/users/bobbi/data2
We can use the ls command to first view all items in this directory:

We can see that this directory contains the following items:
- coaches.txt
- managers
- owners.txt
- players.txt
- rosters
Suppose that we would like to delete all of the files that do not have an extension.
We can use the following syntax to do so:
find . -type f ! -name "*.?*" -delete
The following screenshot shows how to use this syntax in practice:

Notice that when we use the ls command again to view the updated files in the directory we can see that all files that had no extension have been deleted.
