/usr/bin/xargs

Usage: /usr/bin/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, split at newlines;
                                 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
  -o, --open-tty               Reopen standard input as /dev/tty in the child
                                 process before executing the command; useful to
                                 run an interactive application.
  -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

If COMMAND is omitted, the default is 'echo'.
