print [ -nrslzpNDPoOicm ] [ -un ] [ -R [ -en ]] [ arg ...
       ]
       With  no  flags or with flag `-', the arguments are
       printed on the  standard  output  as  described  by
       echo,  with  the  following differences: the escape
       sequence `\M-x' metafies the character x (sets  the
       highest  bit),  `\C-x' produces a control character
       (`\C-@' and `\C-?'  give  the  characters  NUL  and
       delete),  and `\E' is a synonym for `\e'.  Finally,
       if not in an escape sequence, `\' escapes the  fol-
       lowing character and is not printed.

       -r     Ignore the escape conventions of echo.

       -R     Emulate the BSD echo command, which does not
              process escape sequences unless the -e  flag
              is given.  The -n flag suppresses the trail-
              ing newline.  Only the -e and -n  flags  are
              recognized after -R; all other arguments and
              options are printed.

       -m     Take the first argument as a pattern (should
              be  quoted), and remove it from the argument
              list together with subsequent arguments that
              do not match this pattern.

       -s     Place   the  results  in  the  history  list
              instead of on the standard output.

       -n     Do not add a newline to the output.

       -l     Print the arguments  separated  by  newlines
              instead of spaces.

       -N     Print the arguments separated and terminated
              by nulls.

       -o     Print  the  arguments  sorted  in  ascending
              order.

       -O     Print  the  arguments  sorted  in descending
              order.

       -i     If given together with -o or -O, makes  them
              work case independently.

       -c     Print the arguments in columns.

       -un    Print the arguments to file descriptor n.

       -p     Print  the  arguments  to  the  input of the
              coprocess.

       -z     Push the arguments onto the  editing  buffer
              stack,   separated   by  spaces;  no  escape
              sequences are recognized.

       -D     Treat  the  arguments  as  directory  names,
              replacing  prefixes  with  ~ expressions, as
              appropriate.

       -P     Perform prompt expansion  (see  the  section
              `Prompt Expansion').

pushln [ arg ... ]
       Equivalent to print -nz.
