try on your machine

This command is used to set the volume level of an audio sink in PulseAudio, a sound server used in Linux-based operating systems. Here is what each part of the command means:

pactl: This is the command-line tool used to control PulseAudio.
set-sink-volume: This part of the command instructs pactl to set the volume of an audio sink.
${1}: This represents the first argument passed to the command. In shell scripting, this typically refers to a variable or parameter. In this case, it could represent the name or index of the audio sink you want to adjust the volume for.
${0-75}: This represents the volume level to be set for the audio sink. The ${0-75} syntax denotes a range from 0 to 75, meaning the volume can be set anywhere in that range.

So, in summary, this command would be used to set the volume level of a specific audio sink in PulseAudio, with the target audio sink specified by "${1}" and the desired volume level within the range of 0 to 75 specified by "${0-75}".
