I added this to the script:

$MPOST $1.mp
  for file in file.*  do
   $GS -dNOPAUSE -dBATCH -sDEVICE=epswrite -sOutputFile=$file.eps $file
  end

But I get error in line 16:

$ ./mpost-eps webfig
./mpost-eps: 16: Syntax error: word unexpected

File follows here:  mpost-eps:

=======================
$ cat mpost-eps
#!/bin/sh

MPOST=/usr/bin/kertex/mpost
GS=/usr/bin/gs

ERROR="Too few arguments : no file name specified"
[ $# -eq 0 ] && echo $ERROR && exit # no args? ... print error and exit

# check that the file exists
if [ -f $1.mp ]
then
# if it exists then metapost it,then convert with ghostscript, then
remove all the unneeded files

$MPOST $1.mp
  for file in file.*  do
   $GS -dNOPAUSE -dBATCH -sDEVICE=epswrite -sOutputFile=$file.eps $file
  end

#$MPOST $1.mp
#$GS -dNOPAUSE -dBATCH -sDEVICE=epswrite -sOutputFile=$1.eps $1.1

# these lines can be appended to delete other files, such as *.out
if [ -f $1.log ]
then
	rm *.log
fi
else
# otherwise give this output line with a list of available metapost
files echo the file doesnt exist butthead! Choose one of these:
ls *.mp
fi

=======================

It would probably be better if insead of
file.1.eps, file.2.eps, file.3.eps , ... , fileN.eps to write to
file-1.eps, file-2.eps, file-3.eps, ..., file-N.eps.

Some friends tell me that the file generated by metapost is already an
eps file, that I am only making things difficult :(

Thanks for your help & suggestions.
