[SunHELP] dirname command pipe failure

[DAUBIGNE Sebastien - BOR]

Just give it a try :

> echo "my.file.with.lot.of.dots.before.extension" |sed
's/\(.*\)\.[^.]*$/\1/g'
my.file.with.lot.of.dots.before

Thought so, thanks for confirming that.

I don't know the sed command, so will this pipe take the extension off the
filename even if it contains .'s?

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

Try this :

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

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.

Thanks,
