3>cp command.
SUMMARY
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.
SYNTAX:
-a, –archive
Preserve 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.
-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.
man cp is always there.
EXAMPLES:
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
