There you go.
Refer to this line:
Code:
+ grep -q /hd1/home/nick/test1.md5

The fact that the script stops there (and the fact that the command is incomplete) tells us that the error is in the previous command.
Replace the following line:
Code:
FMD5=md5sum $f

With
Code:
FMD5=$(md5sum $f)

The error resides in that the shell is not expanding the result of the md5sum command, therefore you lack one argument in the grep command that follows.
Please let me know how it goes.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
