Depends on which shell. For Kshell, and probably bash, this will work:

Code:
# assume original filename in ofile
filename=${ofile##*/}            # basename -- delete all to the last slant
path=${ofile%$filename}         # delete the filename from the original path/file

Yes, you could use the basename and dirname commands, but those, or any other external command, are much less efficient than using shell built-in variable manipulation.

This does leave path with a trailing /. If you want it removed, add one more line:
Code:
path=${path%/}

Path will of course be empty if the original filename did not have a path component.

gather

GATHER(1)						      General Commands Manual							 GATHER(1)

NAME

       gather - gather up the files in a directory for transmission

SYNOPSIS

       gather [-s] source_dir [-d] dest_dir [-b] bytes [-f] file

OPTIONS

       -b     Desired number of bytes per output file

       -d     Destination directory

       -f     Base name of output files

       -s     Source directory

EXAMPLES

       gather		   # Collect files in current dir into 60K archives

       gather -d dir	   # Put the archives in dir

       gather -b 90000	   # Try to produce 90K archives

       gather -s .. -d targ -b 5000
			   # Try to produce 5K archives

DESCRIPTION

       It  is  often useful to collect all the files in a directory into one or more archives for transmission by mail.  This program collects all
       the files in the source directory (default: current directory) and puts them into a shar archive.  The shar archive is then compressed  and
       uuencoded.   An	attempt is made to have the final .uue file be about the given size (default: 60K), but since gather cannot really predict
       how much shar will add to the file, how much compress will reduce the file, and how much uue will add again, the sizes can  fluctuate.	If
       the  -f	file flag is given, the archives will be given the names file_00.uue, file_01.uue etc.	If -f is not given, the name of the source
       directory is used as the base name.  Since 7 characters of suffix are appended, the base name should not exceed 7 characters.
