Usage: xargs [OPTION]... COMMAND [INITIAL-ARGS]...
Run COMMAND with arguments INITIAL-ARGS and more arguments read from input.

Mandatory and optional arguments to long options are also
mandatory or optional for the corresponding short option.
-0, --null items are separated by a null, not whitespace; disables quote and backslash processing and logical EOF processing
-a, --arg-file=FILE read arguments from FILE, not standard input
-d, --delimiter=CHARACTER items in input stream are separated by CHARACTER, not by whitespace; disables quote and backslash processing and logical EOF processing
-E END set logical EOF string; if END occurs as a line of input, the rest of the input is ignored (ignored if -0 or -d was specified)
-e, --eof[=END] equivalent to -E END if END is specified; otherwise, there is no end-of-file string
-I R same as --replace=R
-i, --replace[=R] replace R in INITIAL-ARGS with names read from standard input; if R is unspecified, assume {}
-L, --max-lines=MAX-LINES use at most MAX-LINES non-blank input lines per command line
-l[MAX-LINES] similar to -L but defaults to at most one non- blank input line if MAX-LINES is not specified
-n, --max-args=MAX-ARGS use at most MAX-ARGS arguments per command line
-P, --max-procs=MAX-PROCS run at most MAX-PROCS processes at a time
-p, --interactive prompt before running commands
--process-slot-var=VAR set environment variable VAR in child processes
-r, --no-run-if-empty 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=MAX-CHARS limit length of command line to MAX-CHARS --show-limits show limits on command-line length
-t, --verbose print commands before executing them
-x, --exit exit if the size (see -s) is exceeded --help display this help and exit --version output version information and exit
