you can redirect STDOUT to /dev/null this will prevent printing output and only prints STDERR to your terminal. You can use it like yourfavouriteprogram > /dev/null And yes, it is faster: time head -100000 large_file.txt real 0m16.570s user 0m0.009s sys 0m0.189s time head -100000 large_file.txt > /dev/null real 0m0.018s user ...

Like the asker, I too mainly used the Dash for opening applications. There are things (e.g. those mentioned above by others) that can speed up the Dash.
