run optistruct via bash file

Hello, 

im trying to do an optimisation on optistruct on Linux

i generatred my fem File with hypermesh on linux,

i did some changes on the fem File via Matlab on linux

i create a new fem File as output and  run the first Iteration manually, the generated, sh file will be placed where the second iteration should be executed 

now my goal is to send a command from matlab to optistruct to run the 2 nd 3rd, n th iteration, the command in matlab look like this 

      system([Argument_1,Argument_2 ,Argument_3]); where Arg_1 is  the Bash file, Arg_2 the fem File, and Arg_3 is the sh file.

my goal is to generate the ouput of the optimization automatically 

the problem here im  new in linux and i dont know what to write as a bash file to run this command.

can you please help me in this topic ??

thx in advance
