shell script problem on sed.

Hi all,
here is my shell script.

  if [ $ABSOLUTE = "1" ]; then
        FTarget="$BACKUPPATH/`date '+%Y%m%d'`"
	desDir = "`echo $FILEPATH | sed -e 's/\/.*/ /'`"
	TmpTarget = $FTarget/$desFir
	if [ ! -d $TmpTarget ]; then
             mkdir -p $TmpTarget
	cp $DATAPATH/$FSource $Tmptarget/.

        FTarget="$BACKUPPATH/`date '+%Y%m%d'`"
	TmpTarget = $FTarget/$FILEPATH
	TmpTrgt = "`cd $TmpTarget | cd .. | pwd`"
        if [ ! -d $TmpTrgt ]; then 
	     mkdir -p $TmpTrgt
	cp $FSource $TmpTrgt/.

what i want to do is :
let say the $FILEPATH = "/tmp/200/readme"
i want the desDir to capture only the "readme" by detect the last "/"
i write the statement like this:
desDir = "`echo $FILEPATH | sed -e 's/\/.*/ /'`"
But failed to get the value, it return empty.

Can anyone teach me how to use the sed or awk? thanks.

Well my suggestion would be not to use sed how awk. Since you seem to be using sh, here's something to try:

echo ${file##*/}

Dissecting ${file##*/} :

${file} : the var we work on

##*/ : replace from beginning of string, up to last occurence of /

The greatest bash doc around is this one:

this is exactly what the command basename does

basename $FILEPATH

this will return 'readme'

with just sed,

echo "/tmp/200/readme" | sed 's/^.*\///'
