How to Use the 'unfile' Command in Linux

`unfile` is a command-line utility in Linux that allows you to remove the file name and extension from a file, while keeping the file's contents intact. It is similar to the `rename` command, but with more advanced features.

Here are some examples of how you can use `unfile`:

1. Remove the file name and extension from all files in a directory:
```
find . -type f -exec unfile {} +
```
This command will remove the file name and extension from all files in the current directory and its subdirectories.

2. Remove the file name and extension from a specific file:
```
unfile myfile.txt
```
This command will remove the file name and extension from the file `myfile.txt`, leaving only the file contents.

3. Remove the file name and extension from all files in a directory, but keep the file's original name:
```
find . -type f -exec unfile {} + --keep-name
```
This command will remove the file name and extension from all files in the current directory and its subdirectories, but keep the file's original name.

4. Remove the file name and extension from a specific file, but keep the file's original name:
```
unfile myfile.txt --keep-name
```
This command will remove the file name and extension from the file `myfile.txt`, but keep the file's original name.

Note that `unfile` only works on files, not directories. If you try to use it on a directory, it will give an error message. Also, be careful when using `unfile` on important files, as it can cause data loss if used incorrectly.
