In the most popular shells, yes. You'd have to use backticks in tcsh.

"Fire command at many files" isn't exactly what xargs does.

It's really for filtering. 'xargs foo' may choose to execute foo many

all that matters is "I want on stdout the results of applying foo to
all those files, in sequence".
