Yes, I am using the bash, but should I use something else to run the commands?
I did run your script, but it didn't do anything.
Didn't get an error and no output files.
Seems like it didn't do anything.

Apologies, your command does work.
thx very much !!
but is it also possible to echo which command is going to run and date in front of every command in the log file?
I can't tell you what interpreter you should use to run your commands other than to say that the interpreter used has to be an interpreter that recognizes the commands it is being asked to run. You are the one who knows what is in the cmd* files. You are the one who knows if those files have a first line of the form #!interpreter. You are the one who knows if the cmd* files have been marked executable or are just readable. Without this information, I don't know what you should do. It just seemed strange that you were writing this script using bash, but using a Bourne shell to run the cmd* files. (Of course, you haven't said what system you're using; so sh and bash may be the same shell.)

Do you want all of the output from all of the cmd* files in one output file? Do you want the standard output from all of the cmd* files in one output file and standard error output from all of the cmd* files in a different output file? Or, do you want the standard output and standard error output for each cmd* file in separate output files (like the script I gave you currently does)?

Do you want the output showing which cmd* file is being started and the timestamp written to the same file as the standard output for the cmd* file that is about to run, to the standard output of the entire script, or to a different log file?

mdm-run

MDM-RUN(1)							   User Commands							MDM-RUN(1)

NAME

       mdm-run - run a command in parallel with mdm-master

SYNOPSIS

       mdm-run command
       mdm-sync command

DESCRIPTION

       mdm-run	annotates  command  as	a  candidate  for parallel execution.  If an mdm-master process is present (i.e., the environment variable
       MDM_CMD_SOCK is defined), mdm-run submits command to the mdm-master, and it exits when the  master  issues  the	command  to  an  mdm-slave
       process	(which may be connected to another terminal) for execution.  mdm-sync runs command in place, but it coordinates with mdm-master to
       ensure that executing command does not interfere with commands that are currently executing in parallel.

       If there is no mdm-master process present (i.e., the environment variable MDM_CMD_SOCK is not defined), both mdm-run  and  mdm-sync  simply
       run command as if you entered command all by itself.

       These programs are a part of the Middleman System (mdm).

OPTIONS

       Neither mdm-run nor mdm-sync accepts any options.

EXIT STATUS

       If  there is no mdm-master process present, the exit status of mdm-run is the exit status of command.  If an mdm-master process is present,
       the exit status is 0 if and only if command is successfully issued to an mdm-slave process for execution.

       The exit status of mdm-sync is always the exit status of command.

ENVIRONMENT

       The mdm system uses the following environment variable for internal communication, and thus you should not try to set them yourself.

       MDM_CMD_SOCK
	      mdm-run uses this environment variable to decide whether a mdm-master process is present.

EXAMPLE

       See mdm.screen(1) for an example use of mdm-run.
