38 .TH XARGS 1 "June 27, 1991"
41 xargs \- construct argument list(s) and execute utility.
51 .RI [ argument " ...]]"
55 utility reads space, tab, newline and end-of-file delimited arguments
56 from the standard input and executes the specified
58 with them as arguments.
60 The utility and any arguments specified on the command line are given
63 upon each invocation, followed by some number of the arguments read
67 is repeatedly executed until standard input is exhausted.
69 Spaces, tabs and newlines may be embedded in arguments using single (`` ' '')
70 or double (``"'') quotes or backslashes (``\e'').
71 Single quotes escape all non-single quote characters, excluding newlines,
72 up to the matching single quote.
73 Double quotes escape all non-double quote characters, excluding newlines,
74 up to the matching double quote.
75 Any single character, including newlines, may be escaped by a backslash.
77 The options are as follows:
80 Set the maximum number of arguments taken from standard input for each
81 invocation of the utility.
86 standard input arguments if the number of bytes accumulated (see the
88 option) exceeds the specified
90 or there are fewer than
92 arguments remaining for the last invocation of
94 The current default value for
99 Set the maximum number of bytes for the command line length provided to
101 The sum of the length of the utility name and the arguments passed to
103 (including NULL terminators) will be less than or equal to this number.
104 The current default value for
109 Echo the command to be executed to standard error immediately before it
115 to terminate immediately if a command line containing
117 arguments will not fit in the specified (or default) command line length.
120 Read null-byte terminated pathnames from standard input as may have been
125 This is a MINIX 3 specific extension to
134 Undefined behavior may occur if
136 reads from the standard input.
139 exits with an exit status of 0 if no error occurs.
142 cannot be invoked, is terminated by a signal or terminates without
146 exits with an exit status of 127.
149 exits with an exit status other than 0,
151 exits with that exit status.
154 exits with an exit status of 1.
161 utility is expected to be POSIX 1003.2 compliant.
