syncdir (수정 #1)

\syncdir
	Synchronizes two directories.
Syntax
	\syncdir [-i] [-I] [-n] [-p] [-u] SOURCE DESTINATION
Description
	\syncdir synchronizes the DESTINATION directory with files and sub-directories as defined in the SOURCE directory. Files or directories found in the DESTINATION directory that do not exist in the SOURCE directory will be removed after synchronization
Options
	-i Prompt before overwrite.
	-I Prompt before removal.
	-n Do not remove those files and directories that are found in DESTINATION but do not exist in SOURCE.
	-p Preserve the last-modified time of the file.
	-u Copy only when the source file is newer than the destination file, or when the destination file is missing.
Notes	If both -I and -n are specified, -n will take precedence.
Examples
	To sync a directory foo with contents of another directory named tariq: \syncdir tariq foo
	To sync a directory and not to remove files/directories in DESTINATION but do not exist in SOURCE. \syncdir -n tariq foo
	To prompt before syncing an existing file, use the -i option: \syncdir -i /home/tariq/sahil /home/foo
