sed or awk delete after last slash
 

Hello,
How can I delete everything after the last slash of a line. For example
form:
/tmp/dir/test
to:
/tmp/dir

Or from:
/dir/tmp/dir/test
To:
/dir/tmp/dir

I know how to delete everything before the last slash:
sed 's!.*/!!'

But how to do it after last the slash?

use the "dirname" command instead, purpose made for exactly that.

sed 's%/[^/]*$%/%'

(Find "/", followed by any number of characters that are NOT "/", at the end of the line; Replace with "/")
