SED: Removing Filenames From Paths
I'm using a script with a lot of SED commands, in conjunction with grep, cut, etc. I've come up against a wall with a particular road block:

I output a file from an SVN registry that gives me a list of files. The list consists of a variable number of lines that contain a path/file. The paths are not a consistent length, hence a variable number of /'s in them. I pipe this output to a file and manipulate that file to create a list of source files for a copy routine I'm writing.

I'd like to be able to read the path line(s) from this file and remove the file name itself thus replicating just the path that I can feed to an rcp command. But I've been hitting a wall as to how to detect the last slash in the line.

from

/u/dir1/dir2/dir3/file
/u/dir1/dir2/file
/u/dir1/file

to

/u/dir1/dir2/dir3/.
/u/dir1/dir2/.
/u/dir1/.

Or blank instead of periods.

I can show you my work / first tries if need be, but it resides in a lab that is cut off from public access, ie: the internet, so I'd have to retype it and thus, why I don't have my first examples here to look at.

Any sort of help would be appreciated, whether it be pointing me to another link (I've been searching this site for quite some time) I haven't found yet or what not.

Thanks folks! -Bruce

raidfile-config

RAIDFILE-CONFIG(8)						    Box Backup							RAIDFILE-CONFIG(8)

NAME

       raidfile-config - Configure Box Backup's RAID files

SYNOPSIS

       raidfile-config config-dir blocksize dir1 [dir2 [dir3]]

DESCRIPTION

       raidfile-config creates a raidfile.conf file for Box Backup. This file holds information about the directories used to store backups in.
       Box Backup supports userland RAID, in a restricted RAID5 configuration, where 3 and only 3 'drives' are supported. You can read more about
       RAID5 (and other RAID-levels) here[1].

   Parameters
       The parameters are as follows:

       config-dir
	   The directory path where configuration files are located. Usually this is /etc/box.	raidfile.conf will be written in this directory.

       blocksize
	   The block size used for file storage in the system, in bytes. Using a multiple of the file system block size is a good strategy.
	   Depending on the size of the files you will be backing up, this multiple varies. Of course it also depends on the native block size of
	   your file system.

       dir1
	   The first directory in the built-in RAID array.

       dir2
	   The second directory in the built-in RAID array. If you are not using the built-in RAID functionality, this field should be ignored.
	   You should not use the built-in RAID if you have a hardware RAID solution or if you're using another type of software RAID (like md on
	   Linux).

       dir3
	   The third directory in the built-in RAID array. The same notes that apply to dir2 also apply to dir3.

       Note that there are currently no way to add multiple disk sets to the raidfile.conf file using command line tools, etc. See
       raidfile.conf(5) for details on adding more disks.
