Where can I find information about hidden Synaptic commands such as synaptic --hide-main-window --non-interactive --parent-window-id --set-selections-file --progress-str --finish-str and also internal options like -o Synaptic::closeZvt=true etc? I see these commands called in programs like AptURL or MintInstall but I cannot find documentation for them.

  • What is your Ubuntu version? LinuxMint is off-topic here.

  • I have Ubuntu MATE Focal and Mint 20. I have synaptic installed in both.

You are right: these arguments are not documented in man synaptic and in builtin help (synaptic --help) either.

So the only possible way to know what these options really do is to read the source code of Synaptic application - check gtk/gsynaptic.cc to get some details.

    Thank you! The link you gave is very useful: it even contains additional commands I wasn't aware of. I guess you are right: the only way to understand how they work is to study the source. I'm reading it now.
