stripping a variable down
I have a variable that has an absolute path for a file on my computer. This dynamically changes. Is there a way I can assign two new variables from that one?
variable: /Users/keith/Desktop/test/file.mov
1) filename - no path or extention ....so just....file
2) path no filename or extention...so just.../Users/keith/Desktop/test
Thanks.

SCAPIN(1) CAO-VLSI Reference Manual SCAPIN(1)
NAME
scapin - Scan path insertion
ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
Paris, France.
Web : http://asim.lip6.fr/recherche/alliance/
E-mail : alliance-users@asim.lip6.fr
SYNOPSIS
scapin [-VRB] [-P file] Input_name Path_name Output_name
DESCRIPTION
SCAPIN is an automatic scan path generator for gate level netlists. SCAPIN inserts a scan path in the netlist Input_name and drives a new
netlist Output_name. This scan path contains all registers specified in the file Path_name.path (see below for the exact syntax). SCAPIN
adds also 3 new connectors in the netlist: scan_in, scan_out and scan_test in order to control the scan path. Eventually SCAPIN adds an
output buffer before the output connector scan_out (option -B).
ENVIRONMENT VARIABLES
MBK_WORK_LIB(1)
indicates the path to the read/write directory for the session.
MBK_IN_LO(1)
indicates the input netlist file format.
MBK_OUT_LO(1)
indicates the output netlist file format.
SCAPIN_PARAM_NAME
indicates the location of a parameter file (with extention .scapin) containing the properties (ports name, models name etc ...)
of all cells needed for the scan path insertion. (see below for the exact syntax)
OPTIONS
-V Sets verbose mode on. Each step is displayed on the standard output.
-R All registers of the scan path are replaced by an equivalent scannable register cell (called reg-mux). (With the default option
a simple multiplexor is added just before all registers of the scan path).
-B Adds an output buffer before the output connector scan_out.
-P file Specifies a parameter file (with extention .scapin) containing the properties of all cells needed for the scan path insertion.
(see below for the exact syntax)

BUF_OUTPUT q
END_BUF
Path_name Specifies a parameter file (with extention .path) containing an ordered list of all instances (registers) of the scan path. It
contains also the name of the 3 connectors scan_in, scan_out and scan_test. (see below for the exact syntax)
# Example of .path file
BEGIN_PATH_REG
cs_0
cs_1
cs_2
END_PATH_REG
BEGIN_CONNECTOR
SCAN_IN scin
SCAN_OUT scout
SCAN_TEST test
END_CONNECTOR
