不如看一下man
NAME
xargs -- construct argument list(s) and execute utility
SYNOPSIS
xargs [-0opt] [-E eofstr] [-I replstr [-R replacements]] [-J replstr]
[-L number] [-n number [-x]] [-s size] [utility [argument ...]]
DESCRIPTION
The xargs utility reads space, tab, newline and end-of-file delimited
strings from the standard input and executes utility with the strings as
arguments.
Any arguments specified on the command line are given to utility upon
each invocation, followed by some number of the arguments read from the
standard input of xargs. The utility is repeatedly executed until stan-
dard input is exhausted.
Spaces, tabs and newlines may be embedded in arguments using single
(`` ' '') or double (``"'') quotes or backslashes (``\''). Single quotes
escape all non-single quote characters, excluding newlines, up to the
matching single quote. Double quotes escape all non-double quote charac-
ters, excluding newlines, up to the matching double quote. Any single
character, including newlines, may be escaped by a backslash. |
