Komenda/polecenie: Jak użyć cp

Back up files that would otherwise be overwritten.

Do not dereference symbolic links; preserve hard-link relationships between source and copy.

Remove existing files in the destination.

Prompt before overwriting destination files. On most systems, this flag is turned off by default except for the root user, who is normally prompted before overwriting files.

Make hard links, not copies, of nondirectories.

Preserve all information, including owner, group, permissions, and timestamps.

Preserve intermediate directories in source. The last argument must be the name of an existing directory. For example, the command:

cp --parents jphekman/book/ch1 newdir

copies the file jphekman/book/ch1 to the file newdir/jphekman/book/ch1, creating intermediate directories as necessary.

Copy directories recursively.

Set suffix to be appended to backup files. This may also be set with the SIMPLE_BACKUP_SUFFIX environment variable. The default is ~. You need to explicitly include a period if you want one before the suffix (for example, specify .bak, not bak).

Make symbolic links instead of copying. Source filenames must be absolute.

Handle files that have "holes" (are defined as a certain size but have less data). always creates a sparse file, auto creates one if the input file is sparse, and never creates a non-sparse file without holes.

Do not copy a file to an existing destination with the same or newer modification time.

Before copying, print the name of each file.

Set the type of backups made. You may also use the VERSION_CONTROL environment variable. The default is existing. Valid arguments are:

t, numbered

Always make numbered backups.

nil, existing

Make numbered backups of files that already have them; otherwise, make simple backups.

never, simple

Always make simple backups.

-x, --one-file-system

Ignore subdirectories on other filesystems.
