Unable to execute the comand on the remote Linux hosts
I have multiple hosts ( More than 20) and need to execute the command but it is not working as expected.
1. This snippet of the code runs on multiple hosts and gives me the process id on the host where i am running .
Code:
for hsts in `cat /a/b/c//hsts.txt` # hsts.txt file contains all the hosts
do
ssh ${id}@${hsts} "cat /z/y/x|tail -1" | awk '{print $30}'
done
2. I need to modify the above command where i need to see the process which is running based on the process id which i am getting from above snippet of the code.
The below snippet runs on individual hosts and it is displaying me the process but if i incorporate the above in the for loop it is not working . Appreciate your help

pvm_delhosts
DELHOSTS(3PVM) PVM Version 3.4 DELHOSTS(3PVM)NAME
pvm_delhosts - Deletes hosts from the virtual machine.
SYNOPSIS
C int info = pvm_delhosts( char **hosts, int nhost, int *infos )
Fortran call pvmfdelhost( host, info )
PARAMETERS
hosts An array of pointers to character strings containing the names of the machines to be deleted.
nhost Integer specifying the number of hosts to be deleted.
infos Integer array of length nhost which contains the status code returned by the routine for the individual hosts. Values less than
zero indicate an error.
host Character string containing the name of the machine to be deleted.
info Integer status code returned by the routine. Values less than nhost indicate partial failure, values less than 1 indicate total
failure.
DESCRIPTION
The routine pvm_delhosts deletes the computers pointed to in hosts from the existing configuration of computers making up the virtual
machine. All PVM processes and the pvmd running on these computers are killed as the computer is deleted. If pvm_delhosts is successful,
info will be nhost. Partial success is indicated by 1<= info < nhost, and total failure by info < 1. The array infos can be checked to
determine which host caused the error.
The Fortran routine pvmfdelhost deletes a single host from the configuration with each call.
If a host fails, the PVM system will continue to function and will automatically delete this host from the virtual machine. An application
can be notified of a host failure by calling pvm_notify. It is still the responsibility of the application developer to make his applica-
tion tolerant of host failure.
EXAMPLES
C:
static char *hosts[] = {
"sparky",
"thud.cs.utk.edu",
};
int status[2];
info = pvm_delhosts( hosts, 2, status );
Fortran:
CALL PVMFDELHOST( 'azure', INFO )
ERRORS
These error conditions can be returned by pvm_delhosts
PvmBadParam
giving an invalid argument value.
PvmSysErr
local pvmd not responding.
