How to execute multiple unix commands in one session from java
Hi,
Iam trying to code in java and wanted to run the commands in the Unix remote servers. I have the following code to run multiple GREP commands in a single session.
But when i execute this, the first command executes successfully, whereas from the next line it says
"Exception Occured
java.io.IOException: A remote execution has already started."
Following is my code snippet :
FileReader fr =
new FileReader("grepcommands.txt");
BufferedReader br = new BufferedReader(fr);
String inputscript="";
sess= conn.openSession();
while((inputscript=br.readLine())!=null){
sess.execCommand(inputscript);
}
sess.close();
It would be great if anyone can provide me the solution for this.

asadmin-multimode
asadmin-multimode(1AS) asadmin-multimode(1AS)
NAME
asadmin-multimode, multimode - allows you to execute multiple commands while preserving environment settings and remaining in the asadmin
utility
SYNOPSIS
multimode [--file filename] [--printprompt=true] [--encoding encode] [--terse=false] [--echo=false]
Use multimode to process the asadmin commands. The command-line interface will prompt you for a command, execute that command, display the
results of the command, and then prompt you for the next command. Additionally, all the asadmin option names set in this mode are used for
all the subsequent commands. You can set your environment and run commands until you exit multimode by typing "exit" or "quit." You can
also provide commands by passing a previously prepared list of commands from a file or standard input (pipe). You can invoke multimode from
within a multimode session; once you exit the second multimode environment, you return to your original multimode environment.
This command is supported in local mode only.
--file reads the commands as defined in the file.
--printprompt allows the printing of asadmin prompt after each command is executed. Set this option to false when the commands
are piped or redirected from the standard input or file. By default the option is set to true.
--encoding specifies the locale for the file to be decoded.
--terse indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-
formatted data for consumption by a script. Default is false.
--echo setting to true will echo the command line statement on to the standard output. Default is false.
Example 1: Using multimode to execute multiple commands
example% asadmin multimode --file commands_file.txt
Where: example% is the system prompt. The multimode settings are executed from the commands_file.txt file.
EXIT STATUS
0 command executed successfully
1 error in executing the command
