This command will get a list of running processes, find lines containing "bash" and save them into filename.txt

ps aux | grep bash > filename.txt

This command will get a list of running processes, find lines containing "bash", sort them alphabetically and save them into filename.txt

ps aux | grep bash | sort > filename.txt

If results of both commands are the same, maybe your lines do not require sorting.
