Try this:

Code:
ls -1 Myfile_name*parameter | awk -F"[._]" '{ printf "mv Myfile_name.%d_parameter Myfile_name.%04d_parameter\n" ,$3,$3 }' | sh

If there are many files and wild char cannot able to expand , use find

ie, instead of ls -1 Myfile_name*parameter , use find . -name "Myfile_name*parameter"

If you are concerned about performance, try using direct syscall to execute a temp script contain the commands

Code:
ls -1 Myfile_name*parameter | awk -F"[._]" '{ printf "mv Myfile_name.%d_parameter Myfile_name.%04d_parameter\n" ,$3,$3 >>"file_out"} END { system("sh file_out") } '
