Sed, bash problems migrating from Cray to GNU/Linux

So, I have a series of ASCII files, all named something like mrkxxxxz.tmp (say, mrk1001z.tmp, mrk1002z.tmp, mrk1003z.tmp,...) -- these are .tmp files created by a large simulation program, and each different .tmp file represents a different parameter space used in the simulation). The simulations were originally run on a Cray, and on said platform, I would run the following shell script (which I call simbatch) to process them, and send them off to a FORTRAN application called 'mark':

Code:

# construct the mark command to run a set of mrkxxxxz.tmp files
echo $@
for i in $@ do
   #echo $i
   out=`echo $i | sed 's/z\./y\./'`
   #echo $out
   res=`echo $i | sed 's/z\./x\./'`
   #echo $res
   vc=`echo $i | sed 's/z\./v\./'`
   #echo $vc
   tmp=`echo $i | sed 's/z\./s\./'`
   #echo $tmp
   echo `date` >>'$tmp'
   nohup mark i='$i' o='$out' r='$res' v='$vc' >&'$tmp' &
done

Now, this works fine on the Cray, but under Linux, nada. I get all sorts of errors:

Code:

'/simbatch: line 5: syntax error near unexpected token `out=`echo $i | sed 's/z\./y\./'`

I'm *guessing* this is a problem with 'quoting' things, but I'll be darned if I've hit on the right combination.

Pointers to the obvious?

Thanks in advance!

bup-fuse

bup-fuse(1)						      General Commands Manual						       bup-fuse(1)

NAME

       bup-fuse - mount a bup repository as a filesystem

SYNOPSIS

       bup fuse [-d] [-f] [-o] <mountpoint>

DESCRIPTION

       bup fuse opens a bup repository and exports it as a fuse(7) userspace filesystem.

       This feature is only available on systems (such as Linux) which support FUSE.

       WARNING: bup fuse is still experimental and does not enforce any file permissions! All files will be readable by all users.

       When you're done accessing the mounted fuse filesystem, you should unmount it with umount(8).

OPTIONS

       -d, --debug
	      run in the foreground and print FUSE debug information for each request.

       -f, --foreground
	      run in the foreground and exit only when the filesystem is unmounted.

       -o, --allow-other
	      permit other users to access the filesystem.  Necessary for exporting the filesystem via Samba, for example.

EXAMPLE

	      rm -rf /tmp/buptest
	      mkdir /tmp/buptest
	      sudo bup fuse -d /tmp/buptest
	      ls /tmp/buptest/*/latest
	      ...
	      umount /tmp/buptest
