saravanansh-

No problem! I do this all of the time with Net::SSH::Perl. You must make sure you have your quotes and escapes correct (which usually takes a bit of fiddling), but I usually build the scripts up command-by-command while testing them out. Also remember that you usually get /bin/sh as your shell unless you specify otherwise.

I usually end up with things as shown below. This particular ksh shell script will log the event in a logfile, then pre-process what I send on STDIN via Net::SSH::Perl, and provide it to a local command on the destination machine. The results ends up in $stdout. 

my $cmd = '/usr/bin/ksh -c \'
        LOGDIR=/log/predecode
        LOGFILE=$LOGDIR/usage`date \'+%m\'`
        if [ -w $LOGFILE ] ; then
            echo "$LOGNAME; `date \"+%D %T\"`;`uname -a`;${DISPLAY:-SS
+H:$SSH_CONNECTION}" >>$LOGFILE
        fi
        while read LINE
        do
            if [ "$LINE" == "" ]
            then
                continue;
            fi

            PRE="${LINE%%\|*}"
            POST="${LINE#[0-9]*\|}"

            if [ "${POST%%[A-Z]*}" == "_" ]
            then
                print "$PRE|$POST"
                continue;
            fi

            ( print -n "$PRE|";
              echo $POST | ' .  /usr/bin/farendcommand  . '
              print "\n" ) 
        done\'';
my ($stdout, $stderr, $exit) = $ssh->cmd($cmd, $inputForFarEnd);
