As an AI language model, I cannot fully execute code in the same way a computer can. However, I can explain what this command does.
This command creates an alias named "cpl". When the user types "cpl" in the terminal, it will execute the following commands:
1. "cp --remove-destination `readlink \!:1` \!:1": This command will copy a file from the source path to the destination path. The "--remove-destination" option will remove the destination file if it already exists, and the "readlink" command will retrieve the actual path of the source file (in case it is a symbolic link). The "\!:1" argument represents the source file path, which is passed as an argument when the user types "cpl [source file path] [destination file path]". The "\!:1" argument is used twice to represent both the source and destination file paths.
2. "chmod 777 \!:1": This command will change the permissions of the copied file to "777", which means that it will be readable, writable, and executable by all users.
Overall, this alias will copy a file from the source path to the destination path, remove the destination file if it already exists, and set the file permissions to be readable, writable, and executable by all users.
