You mean like this, without basename or dirname:


 breakname  "/home/test/with space/tail.e x t"
 
FNAME  (with extension)         = "tail.e x t"
FPATH  (sed)                = /home/test/with space
FNOEXT (without file extension) = tail
FEXT   (file extension alone)   = e x t
 
Reassembling our original CLI filename argument:
/home/test/with space/tail.e x t


================  breakname  ========================

#!/bin/bash
#
# breaks a filename into its path, basename-with-extension,
# basename-without-extension, file-extension alone
#

FN="$@"
echo " "

##################################################

FNAME=$(echo $FN | sed  "s/^.*\///g")
echo "FNAME  (with extension)         = $FNAME"


FPATH=$(echo $FN | sed "s/\/$FNAME//g")
echo "FPATH  (sed)                    = $FPATH"

FNOEXT=$(echo $FNAME | sed "s/\..*$//g" ) 
echo "FNOEXT (without file extension) = $FNOEXT"

#Note the filename and file extension can be extracted either with
# or without the '.' separator. Examples below we throw away the '.'

FEXT=$(echo $FNAME | sed "s/^.*\.//g")
echo "FEXT   (file extension alone)   = $FEXT"

#Note squiggly brackets purely to define a variable-name more clearly,
# as in was it '$FNOEXT' or '$FNOEXT.' that was specified?
 
#We reinsert our missing '.' and '/' if need be
echo " "
 echo "Reassembling our original CLI filename argument:"
echo $FPATH/${FNOEXT}.$FEXT
echo " "
