if I use this code, it works fine.
Code:
ssh batch@192.168.3.222 'if [ -f /home/batch/sample.txt ]; then echo "exist" ; else echo "not exist" ; fi'

it will print out "Exist"



But if I use this code, it display "0".
Code:
a=0
ssh batch@192.168.3.222 'if [ -f /home/batch/sample.txt ]; then a=1 ; else a=2 ; fi'
echo $a

It seems that the value is not assigned to the variable inside the if-else statement.

ecaccess-queue-list

ECACCESS-QUEUE-LIST(1p) 				User Contributed Perl Documentation				   ECACCESS-QUEUE-LIST(1p)

NAME

       ecaccess-queue-list - List available queues

SYNOPSIS

       ecaccess-queue-list -version|-help|-manual

       ecaccess-queue-list [-debug] [queue-name]

DESCRIPTION

       Two different types of queues are in use with ECaccess:

       1 - The ECaccess batch queues, which correspond to one system at ECMWF with its specific batch environment, e.g. ecgate will be the
       ECaccess queue, which will redirect jobs to ecgate at ECMWF, running LoadLeveler. This ECaccess queue will be given as argument when
       submitting a batch job.

       2 - The batch queues (or classes) on the systems at ECMWF will be given in the batch job with #@ class = for LoadLeveler.

       The names of the ECaccess queues and associated batch queues at ECMWF can be seen with this command. When an ECaccess queue-name is
       specified then the details for this queue are displayed (including the list of classes).

       The first ECaccess batch queue in the list is the default queue when submitting a batch job with the ecaccess-job-submit command.

ARGUMENTS

       queue-name (optional)
	       The name of the ECaccess queue to retrieve the details.

OPTIONS

       -version
	       Display version number and exits.

       -help   Print a brief help message and exits.

       -manual Prints the manual page and exits.

       -debug  Display the SOAP messages exchanged.

EXAMPLES

       ecaccess-queue-list

       List all the ECaccess batch queues (or systems supporting job submission at ECMWF).

       ecaccess-queue-list ecgate

       List all the batch queues (or classes) on the ECMWF system ecgate.
