We suppose that we want to duplicate to the /home/usuario/public_html/img directory and all their content. We accede to the directory public_html and we duplicated to the directory img and all their content maintaining its respective permissions in a new called directory imgcopia. He is importande to emphasize that the duplication will work as we waited for if the directory imgcopia does not exist. If he were created previously, a called directory would be created img within the directory imgcopia.
cp - to img imgcopia
To copy all the content of a directory in another directory who already exists
cp - to img/* imgcopia
Dividing of the previous example the commando img in the directory will copy all the content of the directory imgcopia. If in the copy process the origin directory contains archives that already exist in the destiny directory, confirmation for sobreescribirlo will be asked for. So that the system does not ask before sobrewriting an existing file adds option - f.
cp - high frequency img/* imgcopia
The possibility that fits cp exists an alias for the commando so that by defect is executed with the option - i (to ask before sobrewriting, alias cp='cp - i') and the commando - f does not provide effect. In that case you can omit temporarily alias adding one contrabarra or backslash \ before the commando.
\ cp - high frequency img/* imgcopia
