.SH DESCRIPTION
|
||
|
|
xargs reads space, tab, newline and EOF delimited strings from stdin
|
||
|
|
and executes the specified cmd with the strings as arguments.
|
||
|
|
|
||
|
|
Any arguments specified on the command line are given to the command upon
|
||
|
|
each invocation, followed by some number of the arguments read from
|
||
|
|
stdin. The command is repeatedly executed one or more times until stdin
|
||
|
|
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 characters, excluding
|
||
|
|
newlines, up to the matching double quote. Any single character, including
|
||
|
|
newlines, may be escaped by a backslash.
