Corona688,
Thanks for the info.

Quote:
The && will cause the shell to wait before running the command after it, and should any of them fail, none of the ones after it will run. && is a conditional, it's not a background statement. Also, is there any particular reason that string of commands is all in one line? And what is 'echo exec' for, did you mean for that to be without the echo?
I think my line wrapped here when I pasted it which made it a little confusing. I was echoing out that string of commands and piping them into at. I thought that because they were being piped into at that I needed to keep them in the same statement because otherwise the second echo command wouldn't know about the fd assigned to the pipe, but I pretty sure your right that I don't need a fd descriptor. Also, with how I want to do develop this I don't really need to send multiple lines to the fifo without reopening the reader.

Thanks again,


Chris.

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

       asadmin-export(1AS), asadmin-unset(1AS)
