echo - echo arguments to standard output


     /usr/ucb/echo [-n] [argument]


     echo writes its arguments,  separated  by  BLANKs  and  ter-
     minated by a NEWLINE, to the standard output.

     echo is useful for producing diagnostics  in  command  files
     and  for  sending known data into a pipe, and for displaying
     the contents of environment variables.

     For example, you can use echo to  determine  how  many  sub-
     directories  below  the  root  directory (/) is your current
     directory, as follows:

        o  echo your current-working-directory's full pathname

        o  pipe the output through tr  to  translate  the  path's
           embedded slash-characters into space-characters

        o  pipe that output through wc -w  for  a  count  of  the
           names in your path.

           example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"

     See tr(1) and wc(1) for their functionality.

     The shells csh(1), ksh(1), and  sh(1),  each  have  an  echo
     built-in  command,  which, by default, will have precedence,
     and will be invoked if the user calls echo  without  a  full
     pathname.  /usr/ucb/echo and csh's echo() have an -n option,
     but do not understand back-slashed escape  characters.  sh's
     echo(),  ksh's echo(), and /usr/bin/echo, on the other hand,
     understand the black-slashed escape  characters,  and  ksh's
     echo()  also  understands  \a as the audible bell character;
     however, these commands do not have an -n option.


     -n    Do not add the NEWLINE to the output.

     The -n option is a transition aid for BSD applications,  and
     may not be supported in future  releases.
