Copies files from one location to another.cp [options] file1 file2 cp [options] files directory.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.
Preserve attributes of original files where possible. The same as -dpr.
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.
-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).
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.
man cp is always there.
Suppose some image is there in a pen drive named corn and you wanna copy an image named abc.png from it to home directory.First we become a super user by doing su – .Then we use the cp command followed by the path name and the source directory.
~]# cp /media/corn/abc.png /home/yevlempy
