                             output in this column may contain spaces.  A
                             process marked <defunct> is partly dead, waiting
                             to be fully destroyed by its parent.  Sometimes
                             the process args will be unavailable; when this
                             happens, ps will instead print the executable
                             name in brackets.  (alias cmd, command).  See
                             also the comm format keyword, the -f option, and
                             the c option.
                             When specified last, this column will extend to
                             the edge of the display.  If ps can not determine
                             display width, as when output is redirected
                             (piped) into a file or another command, the
                             output width is undefined (it may be 80,
                             unlimited, determined by the TERM variable, and
                             so on).  The COLUMNS environment variable or
                             --cols option may be used to exactly determine
                             the width in this case.  The w or -w option may
                             be also be used to adjust width.

So if ps isn't abiding by your terminal width, be sure the COLUMNS variable is set to a sane value in the user environment and exported, etc.


Thanks but its not working, changed the COLUMNS variable. One thing which works is command line option of --cols which is not desirable as already stated by me in my original question. The value of COLUMNS is 168 but I see that ps command is showing output of much higher width.

dadadodo(1)						      General Commands Manual						       dadadodo(1)

NAME

       dadadodo - exterminate all rational thought

SYNOPSIS

       dadadodo [ options ] [ input-files ]

DESCRIPTION

       dadadodo is a program that analyses texts for Markov chains of word probabilities and then generates random sentences based on those proba-
       bilities.  Sometimes these sentences are nonsense, but sometimes they cut right through to the heart of the matter and reveal hidden  mean-
       ings.

OPTIONS

       dadadodo accepts the following options:

       -c, -count n
	      Generate n sentences.

       -h, -help
	      Show summary of options and exit.

       -html  Output HTML instead of plain text.

       -l, -load file
	      Load compiled data from file ('-' for standard input).

       -o, -output file
	      Save compiled data in file ('-' for standard output).

       -p, -pause s
	      Delay s seconds between paragraphs.

       -w, -columns columns
	      Format  output  for  a  device columns character cells in width.	If not specified, the value of the environment variable COLUMNS is
	      used to determine the width.  If that variable is not defined, a width of 72 is assumed.

NOTES

       Non-option arguments are input files.  These should be text files, but may be mail folders or HTML.  MIME messages  are	handled  sensibly.
       When  no  output  file is specified, sentences will be generated from the input data directly.  However, loading a saved file is far faster
       than re-parsing the text files each time.

ENVIRONMENT

       COLUMNS
	      Determines the width (in character cells) of the output if the -w, -columns option is not used.  If  not	set,  a  width	of  72	is
	      assumed.
