[SunHELP] dirname command pipe failure

[Jopson, Andy]

Blown away. The simplest solution is always the best solution. I'd
appreciate it if you'd answer my other email aswell. It's here now, you can
read minds too?!!!

As you wish. I thought the same about my Masters aswell, redundant rubbish.

" From: "Jopson, Andy" <Andrew.Jopson at Rolls-Royce.com>
" 
" Does anybody know why I can't write the following code as a pipe?
" 
" 	temp=`echo $1 | tr '.' '/'`
" 	temp=`dirname $temp`
" 	echo $temp | tr '/' '.'
" 
" Like this:  echo $1 | tr '.' '/'` | dirname | tr '/' '.'
" 
" It just returns a . rather than the body of a filename (I wrote the code
to
" get whatever comes before the final dot in a filename i.e. it separates
the
" filename from it's extension). It appears that dirname (or basename for
that
" matter) doesn't function in a pipe command.

simplest answer:  use ksh.

echo ${1%.*}
does it right off.  if you want the extension alone,
echo ${1##*.}
instead.

i use ${0##*/} all the time in shell scripts to get the script name.

and could you please trim all the redundant rubbish from the tail of
your replies?  your last answer was over 200 lines!  most of which
were sig after sig after sig...
