timidity:tldr:44564
This command is invoking the Timidity software with a specific filename argument. Here is a breakdown of each component:
-
timidity
: This is the command used to launch the Timidity software. Timidity is a software synthesizer designed to play MIDI files. -
${filename-mid}
: This is a variable substitution using the format${variable-name}
. In this case, the variablefilename
is being used, and-mid
is appended to the value offilename
. The exact value offilename
should be set prior to running this command, and it is expected to be the name of a MIDI file.
The purpose of this command is to open a MIDI file with Timidity for playback or processing. The actual effect will depend on how Timidity is configured and what actions it performs when a MIDI file is provided as an argument.
