How to copy with progress?

To copy files with progress displayed in the terminal, you can use the pv (Pipe Viewer) command in combination with cp. Here's how you can do it:

Install pv (if it's not already installed):
- On Debian/Ubuntu:
```
sudo apt-get install pv
```
- On Red Hat/CentOS:
```
sudo yum install pv
```
Use pv with cp:
You can use the following command to copy a file while showing the progress:
```
pv source_file > destination_file
```
For example:
```
pv largefile.zip > copy_of_largefile.zip
```
Copying a directory:
If you want to copy a directory and show progress, you can use tar in combination with pv:
```
tar cf - source_directory | pv | tar xf - -C destination_directory
```

This will display the progress of the copy operation in the terminal.
