I'm trying to force commands following each other in a script to execute one at a time once the preceding command has finished. I applied the command nice with the options to a list of commands and didn't get the results I was seeking. I'm aware that pidof, grep, sed, and a few others can do the job, but not without a loop. I'm looking for a command that has all the processing built-in without "reinventing-the-wheel."
