Invoking `xargs'
================
xargs [OPTION...] [COMMAND [INITIAL-ARGUMENTS]]
`xargs' exits with the following status:
0
if it succeeds
123
if any invocation of the command exited with status 1-125
124
if the command exited with status 255
125
if the command is killed by a signal
126
if the command cannot be run
127
if the command is not found
1
if some other error occurred.
`--null'
`-0'
Input filenames are terminated by a null character instead of by
whitespace, and the quotes and backslash are not special (every
character is taken literally). Disables the end of file string,
which is treated like any other argument.
`--eof[=EOF-STR]'
`-e[EOF-STR]'
Set the end of file string to EOF-STR. If the end of file string
occurs as a line of input, the rest of the input is ignored. If
EOF-STR is omitted, there is no end of file string. If this
option is not given, the end of file string defaults to `_'.
`--help'
Print a summary of the options to `xargs' and exit.
`--replace[=REPLACE-STR]'
`-i[REPLACE-STR]'
Replace occurrences of REPLACE-STR in the initial arguments with
names read from standard input. Also, unquoted blanks do not
terminate arguments. If REPLACE-STR is omitted, it defaults to
`{}' (like for `find -exec'). Implies `-x' and `-l 1'.
`--max-lines[=MAX-LINES]'
`-l[MAX-LINES]'
Use at most MAX-LINES nonblank input lines per command line;
MAX-LINES defaults to 1 if omitted. Trailing blanks cause an
input line to be logically continued on the next input line, for
the purpose of counting the lines. Implies `-x'.
`--max-args=MAX-ARGS'
`-n MAX-ARGS'
Use at most MAX-ARGS arguments per command line. Fewer than
MAX-ARGS arguments will be used if the size (see the `-s' option)
is exceeded, unless the `-x' option is given, in which case
`xargs' will exit.
`--interactive'
`-p'
Prompt the user about whether to run each command line and read a
line from the terminal. Only run the command line if the response
starts with `y' or `Y'. Implies `-t'.
`--no-run-if-empty'
`-r'
If the standard input does not contain any nonblanks, do not run
the command. By default, the command is run once even if there is
no input.
`--max-chars=MAX-CHARS'
`-s MAX-CHARS'
Use at most MAX-CHARS characters per command line, including the
command and initial arguments and the terminating nulls at the
ends of the argument strings.
`--verbose'
`-t'
Print the command line on the standard error output before
executing it.
`--version'
Print the version number of `xargs' and exit.
`--exit'
`-x'
Exit if the size (see the `-s' option) is exceeded.
`--max-procs=MAX-PROCS'
`-P MAX-PROCS'
Run up to MAX-PROCS processes at a time; the default is 1. If
MAX-PROCS is 0, `xargs' will run as many processes as possible at
a time.
