Have you tried quoting it?

ie: ssh userid@sol8 'fuser blah'

jpiszcz@slack91:~$ ssh -p 22 localhost 'ls -l test'
jpiszcz@localhost's password:
total 4
drwxr-xr-x  2 jpiszcz wheel 4096 Aug 10 13:11 a
-rw-r--r--  1 jpiszcz wheel    0 Aug 10 13:11 b

Subject: ssh remote command fuser does not work

Cannot get remote command fuser to work (although other commands ok) -
keep getting select: Bad file number'

I've set up public/private key authentication between a 
Solaris 9 system running SSH Version Sun_SSH_1.0, protocol versions
1.5/2.0.  and a 
Soalris 8 system running OpenSSH_3.8p1, SSH protocols 1.5/2.0, OpenSSL
0.9.7d 17 Mar 2004

I've got ssh and sftp and scp finally to work, but I am left with one
problem, I can use ssh from sol9 to sol8 to start a remote session. I
can ssh from sol9 to sol8 to execute some remote commands, but not fuser
i.e.  all from the solaris 9 system
ssh userid@anothersol9 ls       works fine
ssh userid@anothersol9 fuser afile      works fine
ssh userid@sol8 ls              works fine
ssh userid@sol8 fuser afile  fails, I get 
select: Bad file number

Having seen this type of message before when it was to do with paths, I
have tried the following...
created a logical link from /usr/bin/fuser to the /usr/sbin/bin/fuser ,
still got the same 'select: Bad file number'
created a test file in the home directory of the userid on the sol8
(server) system and tried 
ssh userid@sol8 ./test          and it worked ok, so I tried creating a
logical link from the home directory of         
                                        userid on sol8 called fuser
poining to /usr/sbin/fuser and tried again
ssh userid@sol8 ./fuser a file  and it still failed with 'select: Bad
file number' . I even tried copying fuser to 
                                        home directory of userid on sol8
, and even though ssh userid@sol8 ./test 
                                        works , ssh userid@sol8 ./fuser
afile   still fails


I'm really stuck , any help/hints  gratefully received
