strip suffix from full path filename

hello,
as far as I know command  basename can strip directory and suffix from filename.
But I want to strip only suffix from filename but keep leading directory components. Is it possible? How?
Thanks

basename strips off the full path leaving only the filename.

dirname strips off the filename leaving only the path

If you are using ksh, you can use the following feature:
You can strip any suffix sequence from a variable called myname with the syntax like ${myname#abc} where abc is the suffix you want to get rid of.  You can use wildcards here, like '.*' to strip any trailing sequence after (and including) the dot.
So:
  myname=/a/b/c/file.ext
  echo ${myname#.*}
will print out the string "/a/b/c/file".
The feature is more general, you can use ## to match and strip the largest match, or use % or %% to strip prefix sequences.

dirname is just what I'm looking for.
I have tried  
         #!/usr/bin/ksh  
         myname=/a/b/c/file.ext
         echo ${myname#.*}
but it does not work.

assuming you're using any kind of shell with myname=/aaa.b/b/c/file.d.ext :

csh#   echo $myname:r
sh#    csh -f -c "set m=$myname; echo \$m:r"
sh#    echo $myname|sed  -e  's/\(.*\)\..*$/\1/'
sh#    echo $myname|gawk -F. '{for (i=1;i<NF-1;i++) {printf("%s.",$i);} print $i}'
ksh#   echo ${myname%.*}

Sorry, I seem to have reversed the % and # signification  (Even worse, I seem to be doing this all the time).  Still, remember the syntax exists because it can be very useful in shell programming.
FYI: bash (popular on Linux systems) also supports this syntax.
