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
