nextfile

nextfile {E}

Stop processing the current input file and start new cycle through

pattern/procedures statements, beginning with the first record of

the next file.

or

or(expr1, expr2) {G}

Return the bitwise OR of expr1 and expr2, which should be values

that fit in a C unsigned long.

print

print [ output-expr[, ...]] [ dest-expr ]

Evaluate the output-expr and direct it to standard output followed

by the value of ORS. Each comma-separated output-expr is sepa-

rated in the output by the value of OFS. With no output-expr, print

$0. The output may be redirected to a file or pipe via the dest-expr,

which is described in “Output Redirections,” later in this chapter.

printf

printf(format [, expr-list ]) [ dest-expr ]

An alternative output statement borrowed from the C language. It

has the ability to produce formatted output. It can also be used to

output data without automatically producing a newline. format is a

string of format specifications and constants. expr-list is a list of

arguments corresponding to format specifiers. As for print, output

may be redirected to a file or pipe. See “printf Formats,” later in

this chapter, for a description of allowed format specifiers.

Like any string, format can also contain embedded escape

sequences: \n (newline) ...
