org.apache.hadoop.fs.shell.WowCopyCommands.Cp

Modifier and Type	Constant Field	Value
public static final String	DESCRIPTION	"Copy files that match the file pattern <src> to a destination. When copying multiple files, the destination must be a directory. Passing -p preserves status [topax] (timestamps, ownership, permission, ACLs, XAttr). If -p is specified with no <arg>, then preserves timestamps, ownership, permission. If -pa is specified, then preserves permission also because ACL is a super-set of permission. Passing -f overwrites the destination if it already exists. raw namespace extended attributes are preserved if (1) they are supported (HDFS only) and, (2) all of the source and target pathnames are in the /.reserved/raw hierarchy. raw namespace xattr preservation is determined solely by the presence (or absence) of the /.reserved/raw prefix and not by the -p option.\n"
public static final String	NAME	"cp"
public static final String	USAGE	"[-f] [-p | -p[topax]] <src> ... <dst>"

org.apache.hadoop.fs.shell.WowCopyCommands.Merge

Modifier and Type	Constant Field	Value
public static final String	DESCRIPTION	"Get all the files in the directories that match the source file pattern and merge and sort them to only one file on local fs. <src> is kept.\n-nl: Add a newline character at the end of each file."
public static final String	NAME	"getmerge"
public static final String	USAGE	"[-nl] <src> <localdst>"

org.apache.hadoop.fs.shell.WowCount

Modifier and Type	Constant Field	Value
public static final String	DESCRIPTION	"Count the number of directories, files and bytes under the paths\nthat match the specified file pattern. The output columns are:\nDIR_COUNT FILE_COUNT CONTENT_SIZE FILE_NAME or\nQUOTA REMAINING_QUOTA SPACE_QUOTA REMAINING_SPACE_QUOTA \n DIR_COUNT FILE_COUNT CONTENT_SIZE FILE_NAME\nThe -h option shows file sizes in human readable format."

org.apache.hadoop.fs.shell.WowDelete.Rm

Modifier and Type	Constant Field	Value
public static final String	DESCRIPTION	"Delete all files that match the specified file pattern. Equivalent to the Unix command \"rm <src>\"\n-skipTrash: option bypasses trash, if enabled, and immediately deletes <src>\n-f: If the file does not exist, do not display a diagnostic message or modify the exit status to reflect an error.\n-[rR]: Recursively deletes directories"
