By the linked question and answer I see that you are using the mpg123
, in the form of:
mpg123 <arquivo_de_som>
If you notice the help of this utility you will see that it has an option to run silently, the -q
. Just change the command to:
mpg123 -q <arquivo_de_som>
In which the q
comes from quiet
.
The help of utility for reference:
