   Sometimes, unexpectedly simple solutions exist :   
      
   prompt>type FFF.TXT | ZZZ-PICK camel barnes camel   
      
   in which FFF.TXT is a readily-constructed file of thousands of lines each   
   containing a single letter F (finishing with a line not starting with F, and   
   not using D).   
      
      
      
   But I have a further problem.  I use MiniTrue to select the desired lines from   
   the main text,   
   with -o meaning 'send the matching lines to Standard Output' -   
   pseudocode:    MINITRUE -o XXX.HTM targets > ZZZ\ZZZZ.TXT   
   and it appears that, in a Windows 10 MS-DOS window and in Windows 10 Windows   
   Terminal,   
   the redirection operation in this case fails to preserve the order of what it   
   transmits   
   (here, that would be regrettable but not disastrous).   
   Perhaps MiniTrue needs an update.  But possibly I can copy the original input   
   file to ZZZ\ZZZZ.TXT   
   and then use -   
   pseudocode:    MINITRUE  ZZZ\ZZZZ.TXT lines-without-targets = ""   ??   
      
   N.B. MiniTrue treats the 'targets' and a row of RegExps, so I can search for   
   'cow' without finding 'Moscow'.   
      
   The question is : what might I use instead of MiniTrue : AWK / GREP / SED   
   /Another ?- I ask to be guided to read about the best one first - and where to   
   get it from.   
      
   Briefly, I need to remove the lines I don't want from a file
