echo(1)

     NAME
          echo - display a line of text

     SYNOPSIS
          echo [-ne] [string ...]
          echo {--help,--version}

     DESCRIPTION
          This documentation is no longer being maintained and may be
          inaccurate or incomplete.  The Texinfo documentation is now
          the authoritative source.

          This manual page documents the GNU version of echo.  Note
          that most shells have a built-in command by the same name
          and with similar functionality.

          echo writes each given string to the standard output, with a
          space between them and a newline after the last one.

        OPTIONS
          -n   Do not output the trailing newline.

          -e   Enable interpretation of the following backslash-
               escaped characters in the strings:
               \a   alert (bell)
               \b   backspace
               \c   suppress trailing newline
               \f   form feed
               \n   new line
               \r   carriage return
               \t   horizontal tab
               \v   vertical tab
               \\   backslash
               \nnn the character whose ASCII code is nnn (octal)

        OPTIONS
          When GNU echo is invoked with exactly one argument, the
          following options are recognized:

          --help
               Print a usage message on standard output and exit
               successfully.

          --version
               Print version information on standard output then exit
               successfully.
