Copying files

The cp command copies files. To copy a file, type cp, the name of the file you want to copy, and the name you want to call the copy, then press <Enter>. Unlike DOS, a UNIX system does not tell you that the copy succeeded, but it shows you an error message if it did not. You can use a pathname (a directory) for the name of the copy to put a copy of a file in a particular directory. In this case, unless you specify otherwise, the copied file will be given the same name as the original but in a different directory.

cp mydir/afile /tmp

Try putting a copy of the message of the day file in your home directory:

1. Type cp /etc/motd $HOME and press <Enter>.

2. Check if the copy was successful by typing l $HOME/motd and pressing <Enter>. The computer shows you a copy of motd in your home directory if the copy worked.

   $ cp /etc/motd $HOME
   $ l $HOME/motd
