cat file | xclip
Here is what the above code is Doing:
1. The first line is a shebang. It tells the computer that this file is a Python script and that it should be run with Python.
2. The second line imports the sys module. This module contains functions and variables that allow you to work with things like the files and command line arguments.
3. The third line imports the pyperclip module. This module contains functions for copying and pasting text to the clipboard.
4. The fourth line defines a main() function. This function is the main part of the program.
5. The fifth line gets the filename from the command line arguments. The sys.argv variable is a list of the command line arguments. The first item in this list is always the name of the program, and the second item is the first command line argument.
6. The sixth line opens the file in read mode.
7. The seventh line reads the contents of the file.
8. The eighth line calls the pyperclip.copy() function to copy the text to the clipboard.
9. The ninth line calls the main() function.
