[SYNOPSIS] xargs OPTION COMMAND
OPTION
-a FILE read arguments from FILE, not standard input

-n MAX-ARGS use at most MAX-ARGS arguments per command line
-P MAX-PROCS run at most MAX-PROCS processes at a time
-p prompt before running commands
-r if there are no arguments, then do not run COMMAND; if this option is not given, COMMAND will be run at least once
-s MAX-CHARS limit length of command line to MAX-CHARS
-t print commands before executing them
