Help with awk adding spaces.
I have a file that contains...

Code:
    
  elm,mail
  elm,lisp,composer,cd,ls,cd,ls,cd,ls,zcat,|,tar,-xvf,ls,cd,ls,cd,ls,vi,ls,cd,ls,vi,elm,-f,ls,rm,ls,cd,ls,vi,vi,ls,vi,ls,cd,ls,elm,cd,ls,cd,ls,vi,vi,vi,ls,vi,ls,i,vi,ls,cp,cd,fg,ls,rm,cd,ls,-l,exit
  elm,mail,biff,elm,biff,elm,elm
  elm,ls
  elm,grep,mail,man,man,-k,fg,look,fg,elm,finger,elm,finger,cd,ls,cd,cd,ls,cd,ls,cd,ls,-l,date,more,ls,-l,more,ls,more,ls,rm,ls,cd,ls,mail,elm,look,fg,fg,cd,cd,ls,cd,ls,cd,ls,cd,ls,vi,man,ls,cd,cd,ls,vi,echo,man,-k,man,ls,cd,ls,biff,ls,elm,fg,exit
  elm,biff,biff,mail,elm,date,rlogin,-l,fg,elm,ls,biff,elm,mesg,finger,finger,talk,logout
  elm,ls,finger,finger,|,more,biff,matlab,clear,elm,rn,ls,matlab,mail,fg,elm,ls,exit
  elm,fk
  matlab
  elm,finger,finger,elm
  cd,ls,cd,ls,ls,-l,sccs,vi,vi,vi,vi,sccs,clear,fg,vi,sccs,ls,ls,-l,vi,vi,vi,vi,clear,sccs,vi,sccs,exit
  elm,mail,exit
  elm,fk,date,mail,exit

I want to print out only the lines that have three words. I use....

Code:
cat workeditf.txt | awk -F"," '{if (NF = 3) print }' > 1.txt

The answer I get...

Code:
  elm mail 
  elm lisp composer
  elm mail biff
  elm ls 
  elm grep mail
  elm biff biff
  elm ls finger
  elm fk 
  matlab  
  elm finger finger
  cd ls cd
  elm mail exit
  elm fk date

The answer I should get...

Code:
  
  elm mail exit

I delete all spaces after each line before I use the awk script. But after the awk script it has blank spaces added on the end of the wrong answers, which I think is causing me to get the wrong answer.

Any suggestions or what other code can I use?

fntsample

fntsample(1)						      General Commands Manual						      fntsample(1)

NAME

       fntsample - PDF and PostScript font samples generator

SYNOPSIS

       fntsample [ OPTIONS ] -f FONT-FILE -o OUTPUT-FILE
       fntsample -h

DESCRIPTION

       fntsample  program  can	be  used  to generate font samples that show Unicode coverage of the font and are similar in appearance to Unicode
       charts. Samples can be saved into PDF (default) or PostScript file.

OPTIONS

       fntsample supports the following options.

       --font-file, -f FONT-FILE
	      Make samples of FONT-FILE.

       --font-index, -n IDX
	      Font index for FONT-FILE specified using --font-file option.  Useful for files that contain multiple fonts,  like  TrueType  Collec-
	      tions (.ttc).  By default font with index 0 is used.

       --output-file, -o OUTPUT-FILE
	      Write output to OUTPUT-FILE.

       --other-font-file, -d OTHER-FONT
	      Compare FONT-FILE with OTHER-FONT.  Glyphs added to FONT-FILE will be highlighted.

       --other-index, -m IDX
	      Font index for OTHER-FONT specified using --other-font-file option.

       --postscript-output, -s
	      Use PostScript format for output instead of PDF.

       --svg, -g
	      Use SVG format for output.  The generated document contains one page.  Use range selection options to specify which.

       --print-outline, -l
	      Print  document  outlines data to standard output.  This data can be used to add outlines (aka bookmarks) to resulting PDF file with
	      pdfoutline program.

       --include-range, -i RANGE
	      Show characters in RANGE.

       --exclude-range, -x RANGE
	      Do not show characters in RANGE.

       --style, -t "STYLE: VAL"
	      Set STYLE to value VAL.  Run fntsample with option --help to see list of styles and default values.

       --help, -h
	      Display help text and exit.

       Parameter RANGE for -i and -x can be given as one integer or a pair of integers delimited by minus sign (-).  Integers can be specified	in
       decimal,  hexadecimal  (0x...) or octal (0...) format.  One integer of a pair can be missing (-N can be used to specify all characters with
       codes less or equal to N, and N- for all characters with codes greather or equal to N).	Multiple -i and -x options can be used.

EXAMPLES

       Make PDF samples for font.ttf and write them to file samples.pdf:
	      fntsample -f font.ttf -o samples.pdf

       Make PDF samples for font.ttf, compare it with oldfont.ttf and highlight new glyphs. Write output to file samples.pdf:
	      fntsample -f font.ttf -d oldfont.ttf -o samples.pdf

       Make PostScript samples for font.ttf and write output to file samples.ps.  Show only glyphs for characters with	codes  less  or  equal	to
       U+04FF but exclude U+0370-U+03FF:
	      fntsample -f font.ttf -s -o samples.ps -i -0x04FF -x 0x0370-0x03FF

       Make PDF samples for font.ttf and save output to file samples.pdf adding outlines to it:
	      fntsample -f font.ttf -o temp.pdf -l > outlines.txt
	      pdfoutline temp.pdf outlines.txt samples.pdf
