[SunHELP] dirname command pipe failure

'dirname' will not read standard input, it justs takes args on the command

Try this :

echo $1 | sed 's/\(.*\)\.[^.]*$/\1/g'

Objet:	[SunHELP] dirname command pipe failure

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.
