Scripting Syntax question

binkyd · 06-23-2020, 06:24 PM

Running this script to start the Pulseaudio Equalizer at startup and minimize it to the tray.
I need a switch to also turn it on, to lazily avoid doing it manually.

Code:

#!/bin/bash
#Equalizer-kdocker-tray
kdocker -d30 -i /usr/share/icons/Papirus-Dark/symbolic/apps/multimedia-equalizer-symbolic.svg /usr/bin/pulseaudio-equalizer-gtk

Couldn't find a man entry for this, and the plain pulseaudio switch of just

Code:

--start

doesn't work.

Any help for this? It's mostly just kinda neat to get it right, btw.

Your scripting syntax is not at question here. The documentation to check are the parameters for kdocker and pulseaudio. That, and to realize that you may be requesting behavior that was not what the maintainers had in mind.

Disclaimer: I do not use kdocker or puleaudio.

Yup.
binkyd, have you reviewed the man pages? I don’t use either package, either. I did glance at dockers man page, where start doesn’t have hyphens. I note that there’s a man page for each function.
The pulse audio man page says—start “implies —daemon” which would suggest checking the daemon config documentation.

I looked for man pages for the equalizer and couldn't find any - as I said.
Beg pardon for mistakenly thinking I was dealing with a syntax problem - but I didn't know what else to call it. How would I better have described my issue?
I checked the pulseaudio stuff - it doesn't seem to apply to the pulseaudio equalizer.

I know there are many program families that have these start-up switches, for example all chromium browsers; I hoped someone would know of some general one for this.

your problem description is incomplete. See for example: http://www.catb.org/~esr/faqs/smart-...html#beprecise

running as which user, from where (shell/gui/cron/whatever), when, ....

I do not really understand where should this switch be applied at all? Would it be a gui element or an option to an app?

what do you mean by "for this"? How did you try that --start at all? What's happened? What does "switch doesn't work" really mean?

please give us more details and you may get better answer[s].

There's no --start among common GTK+ options.

pulseaudio-equalizer-gtk is not the standard GUI 10-band equalizer frontend coming from the PulseAudio project (qpaeq), but the 15-band 3rd party frontend, now abandoned and unmaintained. It has an actively maintained fork though, pulse-audio-equalizer-ladspa. It doesn't seem to have any command line options. See here for how it can be started automatically. I guess you can also use pacmd list-sinks instead of pactl list sinks shown there.

Thank you, shruggy.

I thought this would be a simple little thing....
I guess I'll sign up with Github and try to contact the maintainers.
