cp
cp [options] file1 file2 cp [options] files directory
Description :
Copy file1 to file2, or copy one or more files to the same names under directory. If the destination is an existing file, the file is overwritten; if the destination is an existing directory, the file is copied into the directory (the directory is not overwritten).Options
-a, --archivePreserve attributes of original files where possible. The same as -dpr.
-b, --backup
Back up files that would otherwise be overwritten.
-d, --no-dereference
Do not dereference symbolic links; preserve hard-link relationships between source and copy.
-f, --force
Remove existing files in the destination.
-i, --interactive
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.
-l, --link
Make hard links, not copies, of nondirectories.
-p, --preserve
Preserve all information, including owner, group, permissions, and timestamps.
-P, --parents
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.
-r, -R, --recursive
Copy directories recursively.
-S backup-suffix, --suffix=backup-suffix
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).
-s, --symbolic-link
Make symbolic links instead of copying. Source filenames must be absolute.
--sparse=[always|auto|never]
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.
-u, --update
Do not copy a file to an existing destination with the same or newer modification time.
-v, --verbose
Before copying, print the name of each file.
-V type, --version-control=type
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.
Example
Copy the contents of the guest directory recursively into the /archives/guest/ directory, and display a message for each file copied:cd /archives
cp -av /home/guest guest
cp /home/guest guest
