Full Discussion: Bash- Command run from script does not pass full parameters with spaces inside
Top Forums Shell Programming and Scripting Bash- Command run from script does not pass full parameters with spaces inside Post 302655811 by AcerAspirant on Wednesday 13th of June 2012 07:01:40 PM

That script is really just a reduced and obfuscated equivalent to what my full script is doing- it's building each part of that command piece by piece, including the parameter list, which is parsed elsewhere. When I run it in my shell script like

Code:
$RunDiag ${params[@]}

it fails because if any of the parameters are strings that are like 'string one', the spaces are overwritten sometime in the process into commas.

I've found a solution: change the default IFS temporarily when I run that command, and it works.

Edit: You're right, scrutinizer! It took me some time looking it up but that was the solution, yeah.

cmrunserv

cmrunserv(1m)															     cmrunserv(1m)

NAME

       cmrunserv - run a service from the high availability package run script

SYNOPSIS

       cmrunserv [-v] service_name service_command_string
       cmrunserv [-v] [-r restarts] service_name service_command_string
       cmrunserv [-v] [-R] service_name service_command_string

DESCRIPTION

       cmrunserv is used in the high availability package run script to run a service.

       To  start package's service, a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN allowed in the cluster configu-
       ration file. See access policy in cmquerycl(1m) or cmmakepkg(1m).

       If the service process dies, cmrunserv updates the status of the service to down.  The cluster software will recognize the change in status
       and  execute  the normal package recovery sequence.  This includes executing the package halt script, determining if the package can be run
       on a different node, and, if so, executing the package run script on the new node.

       Should the service_command be halted by the cmhaltserv command, a SIGTERM signal will be sent to the process.   This  executable  or  shell
       script  should be able to handle a SIGTERM signal and execute a graceful shutdown performing any cleanup necessary.  If the process ignores
       the SIGTERM, a SIGKILL will be sent to the process.  If a SIGKILL is sent, the process will die immediately and will be unable  to  perform
       any cleanup.

   Options
       cmrunserv supports the following options.

	      -v	Verbose output will be displayed.

	      -r restarts
			Indicates  that  the  service  should  be automatically restarted by the cluster software if it fails, without halting the
			package. restarts indicates how many times the service may fail before the package should be halted.

	      -R	Indicates the service should be restarted an unlimited number of times if it fails.

	      service_name
			Name of the service as it exists in the package configuration information.

	      service_command_string
			Process string to be started.  This includes the process name and any arguments necessary for the process  to  run.    The
			process name must be a full path, may be either a command name or a shell script, and must be executable.

RETURN VALUE

       cmrunserv returns the following values:

	       0   Successful completion.
	       1   Command failed.

EXAMPLES

       To run the service command string /var/opt/db/database1 under the service name db1, do the following:

	      # Run the process /var/opt/db/database1
	      cmrunserv db1 /var/opt/db/database1

       This line should only be executed within a package run script.

       cmrunserv was developed by HP.
