Type the command, with no options or arguments, that reads items from standard input and builds command lines from them so that another program receives them as arguments.
LPIC-1 Exam 101-500, objective 103. GNU and Unix commands easy
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.

xargs/usr/bin/xargs
Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
xargs is the bridge between a pipe, which delivers text on standard input, and commands such as rm, kill or chmod that expect their operands on the command line. It reads items separated by blanks and newlines, packs as many as fit within the system's argument-length limit, and repeats the command until the input is exhausted. With no command named it defaults to echo.
