Just as a follow-on from this, here's a quick n dirty bit of script

---------------------------------------------------- breakname -------

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

FN="$1"
echo " "

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

FPATH=$(dirname $FN)
echo "FPATH  (dirname)                = $FPATH"

FNAME=$(basename $FN)
echo "FNAME  (with extension)         = $FNAME"

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?
 
echo " "
echo "Getting filename without an extension using 'basename'"
FNOEXT=$(basename $FNAME .${FEXT})
echo "FNOEXT (using 'basename')       = $FNOEXT"

#We reinsert our missing '.' and '/' if need be
echo " "
 echo "Reassembling our original CLI filename argument:"
echo $FPATH/${FNOEXT}.$FEXT
echo " "

------------------------------------------------------------------------

In use:

    breakname /home/fred/tmp/murgatroyd.jones
 

FPATH  (dirname)                = /home/fred/tmp
FNAME  (with extension)         = murgatroyd.jones
FNOEXT (without file extension) = murgatroyd
FEXT   (file extension alone)   = jones
 
Getting filename without an extension using 'basename'
FNOEXT (using 'basename')       = murgatroyd
 
Reassembling our original CLI filename argument:
/home/fred/tmp/murgatroyd.jones
