so what i tried here is i have created multiple text files with different arguments, during ssh i tried to copy these text files to file "args" and tried to execute "executable 2". But i am receving an error saying "Cannot fork into background without a command to execute.".

Can anybody suggest me the solution for this???

Thanks,

Well, case2 appears to be (1) a copy and (2) a command to run. You can do this as if the entire set of commands were passed to "sh -c" as a single argument. That is, put the set of commands, separated by semi-colons (Smilie in double (or single) quotes:
Code:
ssh root@fwlb2 "echo 1; echo 2"

The -f option makes no difference here.
