    The cat utility reads files sequentially, writing them to the standard output. The file operands are processed in command-line order. If file is a single dash (`-‘) or absent, cat reads from the standard input.<\/p>\n

    The echo utility writes any specified operands, separated by single blank (` ‘) characters and followed by a newline (`n’) character, to the standard output. <\/p><\/div>\n<\/p><\/div>\n<\/li>\n
