Re: [Bug-tar] --auto-compress command line option

[Denis Excoffier]

I'm not sure i understand all the implications of what Helmut has  
written. I can add:
- of course the configure options would not be mandatory, and if not  
set, the
  behaviour is like now
- at individual level, to use a compress program of your own, you  
always can take
  benefit of the --use-compress-program command line option
- at site level, the selection of which versions of the compress/gzip/ 
bzip2/lzma
  programs to be used is done by the same people as those that  
select (and
  configure, build, install) the version of tar
- with the --auto-compress option, you don't know in advance which  
compress
  program will be used, therefore in my opinion you cannot use
  --use-compress-program in this case
- yes perhaps my proposal would also need the addition of a bypass  
option, in
  order to the PATH to be used instead of the full path selected at  
configure time
- i only wish to get the same mechanism as with the tar program  
itself. You can say:
  (PATH=/site/local/bin; tar etc.)
  but you can also say
  (/site/local/bin/tar etc.)
  that is: not relying on the PATH if you don't want to
  If you need to enforce a specific set of compress programs, you  
have to wrap tar
  into a subshell like the one Helmut proposes, this is too heavy in  
my opinion, or...
  please Helmut show us your login shell!!!
