How to hide files?

To hide files in a Unix-like operating system, you can rename the file to start with a dot (.). Here’s how to do it:

Using the mv command:
```
mv filename .filename
```
Replace filename with the name of the file you want to hide. This renames the file to .filename, making it hidden.
Creating a new hidden file: You can also create a new hidden file directly by prefixing the filename with a dot:
```
touch .hiddenfile
```

To view hidden files later, use the ls -a command.
